4TB Synology Plus HDD Key Features!

The 4TB Synology Plus (HAT3300-4T) hard disk drive is designed for the light-to-intermediate usage requirements of personal and SMB (small and medium business) NAS systems. Here are its key features:

Manufactured By Seagate

Synology does not make this hard disk drive, which was manufactured by Seagate. Think of this as a Seagate IronWolf hard disk drive that was customised to Synology’s requirements, and with custom firmware for Synology.

Under The PCB

In the following video, we took a look under its PCB, and here was what we found:

The 4TB Synology Plus (HAT3300-4T) comes with a large 256 MB SDRAM cache, courtesy of a Samsung K4B2G1646F memory chip. This is a DDR3-1866 SDRAM chip with 16 memory banks, and a peak transfer rate of about 466 MB/s.

It also uses a Seagate Dillon motor drive controller, which features ST Microelectronics’ proprietary Smooth Drive pseudo-sinusoidal digital drive technology. The drive controller itself has a thermal pad to help keep cool, by transferring heat to the drive chassis.

Finally, this NAS drive has two sensors on its PCB, which allow it to better detect shock and vibration events, and dynamically adjust the flying height of the read/write heads to avoid head crashes.

Always-On Operation

The 4TB Synology Plus is backed by a million hour MTBF (Mean Time Before Failure) rating, and is rated for a workload of 180 TB per year.

That works out to 15 terabytes per month, and is about par for the course for consumer-grade NAS drives.

Easy Firmware Updates

Unlike third-party NAS drives from Western Digital or Seagate, you can easily update the firmware of the 4TB Synology Plus hard disk drive using DiskStation Manager (DSM) in Synology NAS systems.

This is a convenient feature for those who use Synology NAS systems – you won’t need to remove the drive, or use a separate computer, to update its firmware.

Low Power Consumption

Power consumption is pretty low, at just under 5 watts. Even if you run this drive 24/7, it will only consume 42.5 kW per year.

Real world usage will be significantly lower, since NAS systems are designed to power down drives during periods of inactivity.

 

4TB Synology Plus Operating Temperature

We monitored the surface temperature of the three hard disk drives while idle, and during their benchmarks. The following chart shows their operating temperature range, from idle to maximum load.

Please note that instead of giving you the absolute numbers, we are showing the temperature delta, which is the difference between the actual temperature and the ambient room temperature.

The 4TB Synology Plus (HAT3300-4T) appears to run slightly hotter than the 4TB WD Red, but significantly cooler than the 6TB WD Red. This is good news, because it can get really hot inside the NAS enclosure!

WD NAS Can’t Be Seen In Windows? Here Are The Solutions!

You may be wondering why your WD NAS is no longer visible in Windows 10.

Where did it go? How do you get it back?

Find out why your WD NAS cannot no longer be seen in Windows, and what are the solutions!

 

WD NAS Can’t Be Seen In Windows : What Happened?

You may have been using your WD NAS for some time, but one day, its network share – the “drive” that you directly access – can no longer be seen in Windows 10.

The NAS links in Windows File Explorer will only lead you to the login page for the WD NAS management page, not the actual drive where you can directly read, copy, write or edit your files.

All these NAS issues are happening because Microsoft disabled the Network Browse function from Windows 10 v1709 onwards.

The problems started after Windows 10 Fall Creators Update 1709, which :

The Computer Browser service relies on the SMB 1.0 protocol to discover network devices and display them in the Windows Network Neighbourhood.

Disabling SMB 1.0 breaks the Computer Browser service, so it is automatically uninstalled and your NAS drives “disappear” from Network Neighbourhood.

Disabling guest access prevents guest or public access to your NAS drives, even to folders you specifically set to allow for public access. Hence, the Public folder they had access to earlier “disappears”.

 

Why Did Microsoft Disable Those Network Features?

The SMB1 network protocol was first implemented in Windows back in 1992, so it’s old… very old.

It’s so old that it lacks encryption. Everything transmitted via SMB1 can be captured and read, and even modified, by any attacker who gains access to the network.

Guest logins even on SMB2 do not support standard security features like signing and encryption. This makes them vulnerable to man-in-the-middle attacks.

That’s why Microsoft (finally) disabled them both, starting with the Windows 10 Fall Creators Update 1709.

 

WD NAS Can’t Be Seen In Windows : Before We Start…

Preliminary Step #1 : Update Your NAS

Before you do anything, you should log into your WD NAS management system and update its firmware, in case it’s not already set to automatically update.

Updating its firmware will ensure that your NAS supports at least SMB 2, if not SMB 3 as well.

WD NAS Windows URL macOS URL
My Cloud EX2100 http://wdmycloudex2100 http://wdmycloudex2100.local
My Cloud DL2100 http://wdmyclouddl2100 http://wdmyclouddl2100.local
My Cloud EX4100 http://wdmycloudex4100 http://wdmycloudex4100.local
My Cloud DL4100 http://wdmyclouddl4100 http://wdmyclouddl4100.local

Preliminary Step #2 : Use A Higher SMB Protocol

Then, enable the highest SMB protocol your WD NAS supports (Settings > Network). Set it to SMB 3 if possible.

This will ensure that both your WD NAS and your network support the most secure network protocol possible, for your security.

 

WD NAS Can’t Be Seen In Windows : The Solutions!

Best Solution : Map Your WD NAS By Device Name

The best way is to manually map your WD NAS by its device name. This lets you use the more secure SMB2 or SMB3 network protocols, with direct access to your files as usual.

  1. Determine your WD NAS network path, which is based on the device name.If you changed your WD NAS device name to TechARPCloud (for example), the network name will be \\TechARPCloudHere is a list of default network paths for different WD NAS :
WD NAS Default Network Path
My Cloud Home \\MYCLOUD-last 6 digits of serial number
Example : \\MYCLOUD-123456
My Cloud Home Duo
My Cloud \\WDMYCLOUD
My Cloud Mirror \\WDMYCLOUDMIRROR
My Cloud Mirror Gen 2
My Cloud EX2 \\WDMYCLOUDEX2
My Cloud EX2 Ultra \\MYCLOUDEX2ULTRA
My Cloud EX4 \\WDMYCLOUDEX4
My Cloud EX2100 \\WDMYCLOUDEX2100
My Cloud EX4100 \\WDMYCLOUDEX4100
My Cloud DL2100 \\WDMYCLOUDDL2100
My Cloud DL4100 \\WDMYCLOUDDL4100
My Cloud PR2100 \\MYCLOUDPR2100
My Cloud PR4100 \\MYCLOUDPR2100
  1. Open Windows File Explorer and click on Network on the left pane.
  2. Key in the network path of the WD NAS, which is based on its device name. Make sure you include \\ before the network path.

  1. You will be asked to key in a user name and password.
    This can be the administrator’s login, or the login of any registered user of your WD NAS.
    Remember – Windows 10 no longer allows guest logins or public access. So you will need to create a password-protected account even for guests to use.

  1. Once you successfully authenticate your user name and password, the network shares of your WD NAS will become visible in File Explorer under Network!You can stop here, but you will need to keep keying in the network path and login to access your NAS every time you boot into Windows.

  1. For more convenience, you can create a password-protected Private Share.Start by right-clicking on a network share from your WD NAS and select Map network drive…

  1. Select a drive letter for the network share.
    Check Reconnect at sign-in if you don’t want to automatically log into the drive.
    Then click Finish to map the drive.

That’s it! If you expand This PC in Windows File Explorer, you should now see that the WD NAS network drive has now been mapped by its device name!

 

Alternate Solution : Enable Network Discovery Without SMB1

This Windows 10 workaround can be used if your WD NAS supports SMB2 or SMB3 and you prefer not to map the network drives.

  1. Go to Windows Services.
  2. Start these two services :
    Function Discovery Provider Host
    Function Discovery Resource Publication
  3. Set the Startup type for both those services to Automatic (Delayed Start).
  4. Open Windows File Explorer and go to Network.
  5. When prompted, enable Network Discovery.

Your WD NAS shares should now be visible in Windows File Explorer.

 

Worst Case Solution : Enable Network Discovery Without SMB1

This should only be attempted if your WD NAS simply cannot support SMB2 or SMB3, and can only use SMB1.

  1. Go to Control Panel > Programs.
  2. Click on Turn Windows features on or off.
  3. Expand the SMB 1.0/CIFS File Sharing Support option.
  4. Check the SMB 1.0/CIFS Client option.
  5. Click the OK button.
  6. Restart Windows 10

After Windows 10 restarts, your WD NAS shares should now be visible in Windows File Explorer.

How To Create An 8TB SSD As Fast As DDR4 Memory!

The highlight of the WD Black NVMe SSD showcase at Computex 2018 was the massive 8TB SSD RAID array that is as fast as DDR4-2400 memory! Wonder how they accomplished this? Read on and find out!

Updated at 2018-06-22 : Our sincere apologies. We mixed up the system specifications for this SSD RAID Array. It’s actually an AMD Ryzen Threadripper system. We have since corrected the article to reflect this.

 

This 8TB SSD Is As Fast As DDR4 Memory!

As you can see here, Western Digital hit a throughput of 19 GB/s with the Western Digital Black NVMe SSDs (Price Check)! That is as fast as single-channel DDR4-2400 memory!

 

How To Create This Super-Fast 8TB SSD

The secret? Andrew Vo explains how they created this super-fast 8TB SSD RAID array using the Western Digital Black NVMe SSDs (Price Check) in this video.

This is what you will need, if you plan to replicate their project :

Each WD Black NVMe SSD is capable of a peak transfer rate of 2.8 GB/s (write) to 3.4 GB/s (read), so eight of them would have a theoretical throughput limit of 22.4 to 27.2 GB/s!

To hit 19 GB/s, you need to create a RAID 0 array of those eight 1 TB WD Black NVMe SSDs (Price Check), but you can’t use the motherboard’s RAID feature because you would be limited by the 32 Gbps / 4 GB/s DMI bottleneck.

Intel VROC

The ASUS Hyper M.2 X16 Card (Price Check) supports Intel Virtual RAID on CPU (VROC), which reassigns unused PCIe lanes of an Intel Skylake or Coffee Lake processor to boost transfer rates up to 128 Gbps or 16 GB/s.

Of course, those are the theoretical limits, and the actual throughput will be considerably lower than 16 GB/s. To go beyond that, you will need two ASUS Hyper M.2 X16 Cards (Price Check).

AMD Ryzen Threadripper

However, Western Digital used an AMD Ryzen Threadripper system instead. The Threadripper processor has 64 PCIe lanes – plenty for two Hyper M.2 X16 Card (Price Check).

In the end, Western Digital only hit 19 GB/s with two of these cards. This is 30% lower than the theoretical capability of a perfect RAID 0 array of eight 1 TB WD Black NVMe SSDs (Price Check), and 40% lower than the theoretical capability of two ASUS Hyper M.2 X16 Cards (Price Check).

However, without resorting to this method, a motherboard-based RAID 0 array of eight 1 TB WD Black NVMe SSDs (Price Check) would only deliver a maximum transfer rate of just 4 GB/s. Even that’s in a perfect world.

 

How Much Does This Super-Fast SSD RAID Array Cost?

Each 1 TB WD Black NVMe SSDs (Price Check) currently costs $399.99. So the eight SSDs alone cost a princely US$ 3,192 / € 2,765 / RM 12,779.

The ASUS Hyper M.2 X16 Card (Price Check) is much cheaper at just $59 each. That’s an additional US$ 118 / € 102 / RM 472.

All in, this 8 TB SSD RAID array will set you back US$ 3,247 / € 2,812 / RM 12,999. And that does not include the AMD Ryzen Threadripper system=.

No doubt, this is a very expensive project. But think about it – you now have a massive 8 TB SSD RAID 0 array that is as fast as DDR4-2400 memory!

The 1TB WD Blue 3D NAND SSD Up Close!

The 1TB WD Blue 3D NAND SSD (Price Check) comes in a deceptively light cardboard box. Let’s unbox it and take a closer look!

The 1TB WD Blue 3D NAND SSD (Price Check) is a low-profile 2.5″ drive, with a thickness of only 7 mm. This is thinner than the regular 9.5 mm drives, making it suitable for all 2.5″ drive bays, even in thin laptops.

The WD 3D NAND Technology

Western Digital first announced their 64-layer 3D NAND technology, also known as BiCS3, last year. However, it was only slated for commercial volume production in the first half of 2017.

BiCS3 was developed jointly with their technology and manufacturing partner, Toshiba. It not only uses 64-layers, but also 3-bits-per-cell technology to achieve high capacity (256 to 512 gigabits per chip) and performance at a much lower cost.

 

SanDisk nCache 2.0 Technology

SanDisk nCache 2.0 is a proprietary pseudo-SLC caching technology that greatly increases the write performance of the solid state drive. Here is an old infographic (from their Ultra II SSD) that shows how it works :

A small portion (about 4%) of the NAND memory blocks are set to run in the SLC mode, which allows for a much higher write speed. This SLC portion serves as a fast write cache for all writes to the drive, allowing for write speeds of up to 530 MB/s.

The data is later transferred to the TLC portion using the special On Chip Copy feature. This proprietary feature allows the transfer to occur internally on-die without affecting any other transfers.

In a 1TB drive, about 40 GB is reserved for use as the nCache 2.0 write cache. That translates into an effective write cache size of about 13 GB.

The Marvell 88SS1074 SSD Controller

The 1TB WD Blue 3D NAND SSD (Price Check) uses the Marvell 88SS1074 SSD controller, which boasts the following key features :

  • Supports up to 4 NAND channels, with up to 8 NAND chips per channel
  • Features Marvell’s third-generation NANDEdge low-density parity check (LDPC) technology
  • Supports SATA 3.2 (6.0 Gbps)
  • Toggle 2 and ONFI2 support at up to 400 MT/s
  • Integrated DEVSLP (Device Sleep) mode for low power support
  • Supports 256-bit AES hardware encryption
  • Built on 28 nm CMOS process

The Marvell NANDEdge LDPC technology allows for reliable on-the-fly error correction of the 3-bit TLC flash memory, with minimal impact on latency, performance and power consumption.

However, the Marvell 88SS1074 is likely to fall short in sustained throughput, because it only supports 4 NAND channels. Competing controllers like the Phison S10, for example, boast 8 NAND channels, allowing twice as many NAND chips to be accessed simultaneously.

 

SATA 6 Gb/s Interface

The 1TB WD Blue 3D NAND SSD (Price Check) is a Serial ATA drive, with native support for SATA 6 Gb/s interface. It is backward-compatible, so you will have no problem using it with older SATA 3 Gb/s controllers. However, the faster SATA 6 Gb/s interface is necessary for optimal performance because this SSD is capable of a peak transfer rate of 560 MB/s.

Like all Serial ATA drives, it comes with the standard SATA data (left) and power (right) connectors, and is hot-pluggable. That means you can connect and disconnect this solid state drive while the PC is still running. There is no jumper block, because there’s really nothing for you to set. It’s just plug and play!

SSD Endurance

The 1TB WD Blue 3D NAND SSD (Price Check) is rated for a lifetime write lifespan of 400 TBW (Terabytes Written). That does not seem like a lot (equal to overwriting the drive just 400 times), but it is considered enterprise-grade endurance. Many consumer-grade SSDs of equivalent capacity are rated at around 75-100 TBW.

Based on a typical consumer DWPD (Drive Writes Per Day) of 20 GB per day, this 1TB WD Blue 3D NAND SSD (Price Check) will last at least 54 years.

Please note that this long lifespan is due to the large capacity. The 500 GB and 250 GB SanDisk Ultra 3D SSDs are rated at 200 TBW and 100 TBW respectively. That corresponds to an estimated lifespan of 27 years and 13.5 years respectively.

Like all other current SSDs, the 1TB WD Blue 3D NAND SSD (Price Check) comes with certain features to help extend its lifespan :

Wear Levelling

Unlike hard disk drives, flash-based SSDs write and overwrite data in large blocks of 512 KB to 1 MB in size. Even if you only need to write one byte of data, it has to erase and overwrite an entire block. This causes a lot of wear on the memory cells and greatly reduces their lifespan.

To help extend the lifespan of the drive, SSDs perform wear levelling by spreading the writes, so that the flash memory cells have equal wear. The lifespan of the memory cells remain unchanged, but it prevents some of them from failing earlier due to excessive wear.

Write Combine Cache

SSDs also use a write buffer to temporarily store and combine the writes before they are actually written to the flash memory. This reduces the number of block erases required, and consequently, extends the lifespan of the flash memory cells.

The 1TB WD Blue 3D NAND SSD (Price Check) uses the aforementioned nCache 2.0 technology instead of a dedicated SDRAM write combine cache. It reserves about 4% of the NAND blocks and uses them in the SLC mode.

The resulting nCache 2.0 write cache may not be as fast as an SDRAM cache, but it is much larger in size. The 1TB WD Blue SSD, for example, boasts a large 1 GB DDR3L memory cache, but that is nothing compared to the 13 GB (or so) SLC cache in the 1TB WD Blue 3D SSD.

TRIM

Current SSDs support the TRIM command, otherwise known as the ATA8-ACS-2 DATA SET MANAGEMENT command. Operating systems that support TRIM (e.g. Microsoft Windows 7) will notify the SSD when data blocks are deleted in the file system. This allows the SSD to perform garbage collection in the background – internally erasing the affected blocks so that they are ready to be written to.

Without the TRIM command, the SSD will not know when a block of data has been deleted by the operating system. When new data is written to the same block of data, it will force the SSD to perform the time-consuming read-erase-modify-write cycle, which not only cripples performance but also increases wear on the affected memory cells.

Multi-Stream

This is a new SSD technology that was introduced in May 2015, as part of the T10 SCSI Standard. Multi-stream greatly improves performance and extends lifespan by reducing or even eliminating garbage collection.

It achieves this by marking data writes that are associated with one another, or have a similar lifetime, with a unique stream ID. This allows the SSD controller to pack all data writes with the same stream ID into the same block.

When the operating system deletes data, it is likely that they are all packed into the same block. If the block has not been written to the SSD, then this eliminates the pending write operation completely. If the block has been written to the SSD, then this would only require that single block to be erased, instead of multiple blocks (which would happen if the data was not all packed into the same block).

 

SSD Maintenance

First of all, you should never, ever defragment solid state drives. Spatial fragmentation of data on the SSD has no effect on its performance. Fragmented data are accessed as quickly as nicely-packed blocks, so it’s pointless to defragment the data blocks. Doing so will only reduce the lifespan of the flash memory cells by putting them under additional wear.

3D NAND flash memory will only last about 1,000 erase/write cycles – about the same as TLC NAND memory. You will want to minimise the number of times each flash memory cell is erased.

[adrotate group=”2″]

You should also use an operating system that supports the TRIM command. If you are using one of the following operating systems, then you have nothing to worry about :

  • Microsoft Windows 7, or better
  • Microsoft Windows Server 2008 R2, or better
  • Linux 2.6.33, or better
  • FreeBSD 8.2, or better
  • Mac OS X Snow Leopard, or better

If not, you should consider upgrading your operating system. Otherwise, you will need to perform manual garbage collection on a regular basis, either using a manufacturer utility, or newer defragmentation software that specifically supports solid state drives.

Basically, these utilities will retrieve the list of free blocks from the operating system’s file system and pass it to the SSD in the form of TRIM commands, so that it will know which blocks to erase internally. Again, these utilities are not necessary if you are using an operating system that supports TRIM.

Testing Methodology

 

Over-Provisioning & Usable Capacity

This 1TB WD Blue 3D NAND SSD (Price Check) has a maximum storage capacity of 1,024 GB, courtesy of eight 128 GB SanDisk 3D NAND chips. Of that, a mere 24 GB has been set aside for garbage collection, wear levelling and replacement of failing blocks.

Ordinarily, the limited 2.4% over-provisioning may impact long-term performance and lifespan. However, Western Digital mitigated that using a large 13 GB pseudo-SLC write cache they call nCache 2.0.

After it is formatted in NTFS, the actual formatted capacity is 1,000,202,039,296 bytes. This is slightly (202 MB) more than the official formatted capacity of 1,000 GB.

With about 124 MB of space allocated to the NTFS file system, the actual usable capacity is just above 1,000 GB.

Transfer Rate Range

This chart shows you the range of memory cell-to-controller transfer rates for SSDs, or the range of platter-to-buffer transfer rates from the innermost track to the outermost track in HDDs.

Despite boasting an official peak read speed of 560 MB/s, the 1TB WD Blue 3D NAND SSD (Price Check) could only hit 386 MB/s. That is impressive in its own right, but puts it below the 256 GB OCZ Vector and the 240 GB HyperX Savage SSDs.

ATTO Disk Benchmark

ATTO Disk Benchmark is a free benchmark that allows you to compare the performance of solid state drives using a variety of transfer sizes. It also allows us to determine if the SSD performs data compression to improve performance, and extend lifespan.

 

I/O Comparison

Results Compressible Data Non-Compressible Data
Minimum Maximum Minimum Maximum
Read Speed 6.5 MB/s 145.1 MB/s 5.8 MB/s 143.6 MB/s
Write Speed 5.6 MB/s 137.2 MB/s 6.1 MB/s 134.2 MB/s

The Marvell 88SS1074 controller does not perform any data compression, which is why the performance results are the same for both compressible and non-compressible data. The 1TB WD Blue 3D NAND SSD (Price Check) reached its peak transfer rate with a block size of 1 MB.

 

Multiple I/O Comparison

Results Compressible Data Non-Compressible Data
Minimum Maximum Minimum Maximum
Read Speed 8.8 MB/s 147 2 MB/s 10.2 MB/s 147.5 MB/s
Write Speed 8.3 MB/s 139.6 MB/s 9.0 MB/s 136.5 MB/s

With just 8 simultaneous transactions, the 1TB WD Blue 3D NAND SSD (Price Check) reached its peak transfer rate with a block size of 128 KB.

 

Our Verdict & Award

The first 1 terabyte solid state drive we tested was the 1TB WD Blue (WDS100T1B0A) SSD. While it had a large storage capacity, high endurance and a affordable price point, it was not particularly fast.

That changed with the introduction of the 64-layer 3D NAND technology, which not only increases storage capacity and performance, but also reduces cost and power consumption. Now we can have our cake and eat it too.

The 1TB WD Blue 3D SSD (Price Check) is the first Western Digital solid state drive to make use of the 64-layer 3D NAND technology and it sure impressed us with its performance.

Despite using the same SSD controller as the 1TB WD Blue, the 1TB WD Blue 3D NAND SSD (Price Check) was twice as fast in large reads and writes. It accomplished this without using any SDRAM cache, thanks to nCache 2.0 technology.

[adrotate group=”2″]

The 1TB WD Blue 3D NAND SSD (Price Check) will work well as a boot drive, thanks to its excellent small random performance. It will be particularly attractive as an upgrade option for laptops still running on hard disk drives, or smaller SSDs.

Just note that its high performance requires a significant amount of CPU performance. So make sure you pair it with a fast processor.

We like its combination of great performance, large storage capacity and lower cost so much, we think it deserves our Editor’s Choice Award. Great work, Western Digital!

How To Choose The Best Drive For Your PC

Western Digital colour-codes their hard disk drives not to make the drives look sexier, or to help sell more hard disk drives. They created the WD drive colours to help users understand the distinct advantages or use of each drive family. In this article, Western Digital will help us show you how to choose the best drive for your PC.

 

Every Drive Has A Purpose

There is no better person than Albert Chang, Senior Manager of Product Marketing at WD Asia Pacific, to explain why every drive has a purpose. He also points out a key point that users often forget to factor when consumers purchase a drive – the TCO (Total Cost of Ownership).

That’s right. The TCO is often overlooked, because that is ultimately the price you are paying over the lifetime of a drive. So make sure you don’t just buy the cheapest possible drive, because that may result in a high TCO… including the loss of priceless data.

 

Introducing The Five WD Drive Colours

Here is a quick primer on the five WD drive colours, and how they can help you determine the best drive for your PC.

Now, let’s take a closer look at each WD drive colour, and find out what advantages each drive colour boasts!

[adrotate group=”1″]

 

WD Blue For Mainstream PCs

The WD Blue (Price Check) family are focused on offering highly-affordable drives with large storage capacities.

The WD Blue family does not just consist of hard disk drives. Western Digital also offers WD Blue SSHDs (solid state hybrid drives) and WD Blue SSDs (solid state drives).

For more information, you can read these WD Blue articles :

 

WD Black For High Performance PCs

The WD Black family (Price Check) is targeted at power users and gamers who want the fastest possible hard disk drives for their PCs.

The WD Black drives offer a much higher spindle speed, a very large cache, and a fast processor. For more information, you can read these WD Black articles :

 

WD Red For NAS Storage

The WD Red (Price Check) family of NAS drives is specifically designed for the “always on” environment of a NAS enclosure. They run cooler and vibrate less, greatly increasing their reliability and lifespan in NAS enclosures.

The WD Red drives are also optimised for NAS usage patterns (80% reads, 20% writes), so you will be able to access your files faster than with a regular hard disk drive.

For more information, you can read these WD Red articles :

 

WD Purple For Surveillance

WD Purple drives (Price Check) are designed to handle the high-temperature, “always-on” environment of the CCTV and DVR systems. Regular drives will fail quickly under such conditions.

They are also designed to handle multiple video streams without dropped frames, or gaps in recorded footage… and do this 24/7 without rest!

For more information on the WD Purple, and why it is the best drive for surveillance and CCTV systems, please read :

 

WD Gold For Datacenters

Qualified for nearline storage use in datacenters, datacenter hard disk drives like WD Gold (Price Check) are designed to offer high storage capacities at maximum performance and reliability while operating continuously 24 hours a day in large drive arrays.

So if you want nothing but the best drive to secure your company’s data, there can be no doubt that the WD Gold (Price Check) is the ultimate storage solution.

For more information, you can read these WD Gold articles :

 

What Is The Best Drive For YOU?

The WD drive colours make it extremely simple for you to choose the best drive for the job.

If you want the best hard disk drive for your gaming PC or laptop, the WD Black drives are your best options.

If you just need to store a large amount of data at very low cost, the WD Blue drives are your best bet.

If you have a NAS enclosure, you will not want to use any other drives but WD Red drives for better performance and reliability.

If you have a CCTV system, you will not want to use any other drives but WD Purple drives for stutter-free recording and a long lifespan.

If you are running a server, you will want the high performance and exceptional reliability of the WD Gold drives.

See? The WD drive colours make it extremely easy for you to find the best drive for the job!

The WD 3D NAND Technology

Western Digital first announced their 64-layer 3D NAND technology, also known as BiCS3, last year. However, it was only slated for commercial volume production in the first half of 2017.

BiCS3 was developed jointly with their technology and manufacturing partner, Toshiba. It not only uses 64-layers, but also 3-bits-per-cell technology to achieve high capacity (256 to 512 gigabits per chip) and performance at a much lower cost.

 

SanDisk nCache 2.0 Technology

SanDisk nCache 2.0 is a proprietary pseudo-SLC caching technology that greatly increases the write performance of the solid state drive. Here is an old infographic (from their Ultra II SSD) that shows how it works :

A small portion (about 4%) of the NAND memory blocks are set to run in the SLC mode, which allows for a much higher write speed. This SLC portion serves as a fast write cache for all writes to the drive, allowing for write speeds of up to 530 MB/s.

The data is later transferred to the TLC portion using the special On Chip Copy feature. This proprietary feature allows the transfer to occur internally on-die without affecting any other transfers.

In a 1TB drive, about 40 GB is reserved for use as the nCache 2.0 write cache. That translates into an effective write cache size of about 13 GB.

The Marvell 88SS1074 SSD Controller

The 1TB SanDisk Ultra 3D SSD (Price Check) uses the Marvell 88SS1074 SSD controller, which boasts the following key features :

  • Supports up to 4 NAND channels, with up to 8 NAND chips per channel
  • Features Marvell’s third-generation NANDEdge low-density parity check (LDPC) technology
  • Supports SATA 3.2 (6.0 Gbps)
  • Toggle 2 and ONFI2 support at up to 400 MT/s
  • Integrated DEVSLP (Device Sleep) mode for low power support
  • Supports 256-bit AES hardware encryption
  • Built on 28 nm CMOS process

The Marvell NANDEdge LDPC technology allows for reliable on-the-fly error correction of the 3-bit TLC flash memory, with minimal impact on latency, performance and power consumption.

However, the Marvell 88SS1074 is likely to fall short in sustained throughput, because it only supports 4 NAND channels. Competing controllers like the Phison S10, for example, boast 8 NAND channels, allowing twice as many NAND chips to be accessed simultaneously.

 

SATA 6 Gb/s Interface

The 1TB SanDisk Ultra 3D SSD (Price Check) is a Serial ATA drive, with native support for SATA 6 Gb/s interface. It is backward-compatible, so you will have no problem using it with older SATA 3 Gb/s controllers. However, the faster SATA 6 Gb/s interface is necessary for optimal performance because this SSD is capable of a peak transfer rate of 560 MB/s.

Like all Serial ATA drives, it comes with the standard SATA data (left) and power (right) connectors, and is hot-pluggable. That means you can connect and disconnect this solid state drive while the PC is still running. There is no jumper block, because there’s really nothing for you to set. It’s just plug and play!

SSD Endurance

The 1TB SanDisk Ultra 3D SSD (Price Check) is rated for a lifetime write lifespan of 400 TBW (Terabytes Written). That does not seem like a lot (equal to overwriting the drive just 400 times), but it is considered enterprise-grade endurance. Many consumer-grade SSDs of equivalent capacity are rated at around 75-100 TBW.

Based on a typical consumer DWPD (Drive Writes Per Day) of 20 GB per day, this 1TB SanDisk Ultra 3D SSD (Price Check) will last at least 54 years.

Please note that this long lifespan is due to the large capacity. The 500 GB and 250 GB SanDisk Ultra 3D SSDs are rated at 200 TBW and 100 TBW respectively. That corresponds to an estimated lifespan of 27 years and 13.5 years respectively.

Like all other current SSDs, the 1TB SanDisk Ultra 3D SSD (Price Check) comes with certain features to help extend its lifespan :

Wear Levelling

Unlike hard disk drives, flash-based SSDs write and overwrite data in large blocks of 512 KB to 1 MB in size. Even if you only need to write one byte of data, it has to erase and overwrite an entire block. This causes a lot of wear on the memory cells and greatly reduces their lifespan.

To help extend the lifespan of the drive, SSDs perform wear levelling by spreading the writes, so that the flash memory cells have equal wear. The lifespan of the memory cells remain unchanged, but it prevents some of them from failing earlier due to excessive wear.

Write Combine Cache

SSDs also use a write buffer to temporarily store and combine the writes before they are actually written to the flash memory. This reduces the number of block erases required, and consequently, extends the lifespan of the flash memory cells.

The 1TB SanDisk Ultra 3D SSD (Price Check) uses the aforementioned nCache 2.0 technology instead of a dedicated SDRAM write combine cache. It reserves about 4% of the NAND blocks and uses them in the SLC mode.

The resulting nCache 2.0 write cache may not be as fast as an SDRAM cache, but it is much larger in size. The 1TB WD Blue SSD, for example, boasts a large 1 GB DDR3L memory cache, but that is nothing compared to the 13 GB (or so) SLC cache in the 1TB SanDisk Ultra 3D SSD.

TRIM

Current SSDs support the TRIM command, otherwise known as the ATA8-ACS-2 DATA SET MANAGEMENT command. Operating systems that support TRIM (e.g. Microsoft Windows 7) will notify the SSD when data blocks are deleted in the file system. This allows the SSD to perform garbage collection in the background – internally erasing the affected blocks so that they are ready to be written to.

Without the TRIM command, the SSD will not know when a block of data has been deleted by the operating system. When new data is written to the same block of data, it will force the SSD to perform the time-consuming read-erase-modify-write cycle, which not only cripples performance but also increases wear on the affected memory cells.

Multi-Stream

This is a new SSD technology that was introduced in May 2015, as part of the T10 SCSI Standard. Multi-stream greatly improves performance and extends lifespan by reducing or even eliminating garbage collection.

It achieves this by marking data writes that are associated with one another, or have a similar lifetime, with a unique stream ID. This allows the SSD controller to pack all data writes with the same stream ID into the same block.

When the operating system deletes data, it is likely that they are all packed into the same block. If the block has not been written to the SSD, then this eliminates the pending write operation completely. If the block has been written to the SSD, then this would only require that single block to be erased, instead of multiple blocks (which would happen if the data was not all packed into the same block).

 

SSD Maintenance

First of all, you should never, ever defragment solid state drives. Spatial fragmentation of data on the SSD has no effect on its performance. Fragmented data are accessed as quickly as nicely-packed blocks, so it’s pointless to defragment the data blocks. Doing so will only reduce the lifespan of the flash memory cells by putting them under additional wear.

3D NAND flash memory will only last about 1,000 erase/write cycles – about the same as TLC NAND memory. You will want to minimise the number of times each flash memory cell is erased.

[adrotate group=”2″]

You should also use an operating system that supports the TRIM command. If you are using one of the following operating systems, then you have nothing to worry about :

  • Microsoft Windows 7, or better
  • Microsoft Windows Server 2008 R2, or better
  • Linux 2.6.33, or better
  • FreeBSD 8.2, or better
  • Mac OS X Snow Leopard, or better

If not, you should consider upgrading your operating system. Otherwise, you will need to perform manual garbage collection on a regular basis, either using a manufacturer utility, or newer defragmentation software that specifically supports solid state drives.

Basically, these utilities will retrieve the list of free blocks from the operating system’s file system and pass it to the SSD in the form of TRIM commands, so that it will know which blocks to erase internally. Again, these utilities are not necessary if you are using an operating system that supports TRIM.

Testing Methodology

 

Over-Provisioning & Usable Capacity

This 1TB SanDisk Ultra 3D SSD (Price Check) has a maximum storage capacity of 1,024 GB, courtesy of eight 128 GB SanDisk 3D NAND chips. Of that, a mere 24 GB has been set aside for garbage collection, wear levelling and replacement of failing blocks.

Ordinarily, the limited 2.4% over-provisioning may impact long-term performance and lifespan. However, SanDisk mitigated that using a large 13 GB pseudo-SLC write cache they call nCache 2.0.

After it is formatted in NTFS, the actual formatted capacity is 1,000,202,039,296 bytes. This is slightly (202 MB) more than the official formatted capacity of 1,000 GB.

With about 124 MB of space allocated to the NTFS file system, the actual usable capacity is just above 1,000 GB.

 

Transfer Rate Profile

We compared the 1TB SanDisk Ultra 3D SSD (Price Check) to the 1TB WD Blue SSD. As you can see, it has a sustained throughput of about 410 MB/s, which makes it almost twice as fast as the 1TB WD Blue SSD, which uses TLC NAND memory.

Transfer Rate Range

This chart shows you the range of memory cell-to-controller transfer rates for SSDs, or the range of platter-to-buffer transfer rates from the innermost track to the outermost track in HDDs.

Despite boasting an official peak read speed of 560 MB/s, the 1TB SanDisk Ultra 3D SSD (Price Check) could only hit 411 MB/s. That is impressive in its own right, but puts it below the 256 GB OCZ Vector and the 240 GB HyperX Savage SSDs.

ATTO Disk Benchmark

ATTO Disk Benchmark is a free benchmark that allows you to compare the performance of solid state drives using a variety of transfer sizes. It also allows us to determine if the SSD performs data compression to improve performance, and extend lifespan.

 

I/O Comparison

Results Compressible Data Non-Compressible Data
Minimum Maximum Minimum Maximum
Read Speed 11.6 MB/s 426.1 MB/s 11.6 MB/s 427.1 MB/s
Write Speed 7.6 MB/s 526.3 MB/s 7.6 MB/s 525.1 MB/s

The Marvell 88SS1074 controller does not perform any data compression, which is why the performance results are the same for both compressible and non-compressible data. The 1TB SanDisk Ultra 3D SSD (Price Check) reached its peak transfer rate with a block size of 1 MB.

 

Multiple I/O Comparison

Results Compressible Data Non-Compressible Data
Minimum Maximum Minimum Maximum
Read Speed 25.8 MB/s 559 2 MB/s 26.7 MB/s 580.5 MB/s
Write Speed 16.2 MB/s 538.1 MB/s 16.1 MB/s 538.1 MB/s

With just 8 simultaneous transactions, the 1TB SanDisk Ultra 3D SSD (Price Check) reached its peak transfer rate with a block size of 128 KB.

 

Our Verdict & Award

The first 1 terabyte solid state drive we tested was the 1TB WD Blue (WDS100T1B0A) SSD. While it had a large storage capacity, high endurance and a affordable price point, it was not particularly fast.

That changed with the introduction of the 64-layer 3D NAND technology, which not only increases storage capacity and performance, but also reduces cost and power consumption. Now we can have our cake and eat it too.

The 1TB SanDisk Ultra 3D SSD (Price Check) is the first SanDisk solid state drive to make use of the 64-layer 3D NAND technology and it sure impressed us with its performance.

Despite using the same SSD controller as the 1TB WD Blue, the 1TB SanDisk Ultra 3D SSD (Price Check) was twice as fast in large reads and writes. It accomplished this without using any SDRAM cache, thanks to nCache 2.0 technology.

[adrotate group=”2″]

The 1TB SanDisk Ultra 3D SSD (Price Check) will work well as a boot drive, thanks to its excellent small random performance. It will be particularly attractive as an upgrade option for laptops still running on hard disk drives, or smaller SSDs.

Just note that its high performance requires a significant amount of CPU performance. So make sure you pair it with a decent processor.

We like its combination of great performance, large storage capacity and lower cost so much, we think it deserves our Editor’s Choice Award. Great work, SanDisk!

 

SanDisk Ultra 3D SSD Price Check

The SanDisk Ultra 3D SSDs are available in storage capacities from 250 GB to 2 TB in the 2.5-inch / 7mm cased drive form factor.

WD Introduces MAMR Technology For 40TB & Beyond!

October 13, 2017 — Western Digital just announced a breakthrough innovation for delivering ultra-high capacity hard disk drives (HDDs) to meet the future demands of Big Data with proven data center-level reliability. They also demonstrated world’s first microwave-assisted magnetic recording (MAMR) HDD and presentations from company executives and the inventor of MAMR technology, Professor Jimmy Zhu from Carnegie Mellon University.

Western Digital also showcased advancements in micro actuation and Damascene recording head technology. Western Digital expects to begin shipping ultra-high capacity MAMR HDDs in 2019 for use in data centers that support Big Data applications across a full range of industries.

 

The MAMR Technology

MAMR is one of two energy-assisted technologies that Western Digital has been developing for years. They recently innovated a breakthrough in material and process that provides the required reliable and predictable performance, as well as the manufacturability to accelerate areal density and cost improvements to an estimated average of 15% per year.

Developments in the other energy-assisted technology, specifically, heat-assisted magnetic recording (HAMR), present new material science and reliability challenges that are not a factor in MAMR. Only MAMR demonstrates the reliability and cost profile that meets the demands of data center operators.

At the heart of the company’s innovation breakthrough is the “spin torque oscillator” used to generate a microwave field that increases the ability to record data at ultra-high density without sacrificing reliability. Western Digital’s innovative MAMR technology is expected to offer over 4 terabits-per-square-inch over time. With sustained improvements in recording density, MAMR promises to enable hard drives with 40TB of capacity and beyond by 2025, and continued expansion beyond that timeframe.

[adrotate group=”2″]

Western Digital’s MAMR technology is the latest innovation to significantly improve areal densities. It builds upon a number of other leading innovations from the company. In addition to HelioSeal helium-filled drive technology, MAMR also builds upon the company’s micro actuation and recording head manufacturing technologies.

Western Digital’s advanced micro actuation technology for data center applications enables hard drives to accurately and reliably position magnetic heads for writing and reading at ultra-high densities. Their head manufacturing operations are the only internal supplier to utilize Damascene processing to manufacture heads with the precise tolerances and complex structures required for reliable and cost-effective recording at ultra-high densities.

The Damascene process also provides the capability to embed the spin torque oscillator that enables the manufacturing of MAMR heads. The combination of these technologies deliver superior total cost of ownership (TCO) across all sizes of cloud and enterprise data centers.

10TB WD Red (WD100EFAX) Hard Disk Drive Review

In this review, we are going to look at the first helium-filled WD Red model – the 10TB WD Red (Lowest Price) NAS drive!

 

The WD Red Family

The popularity of Network-Attached Storage (NAS) systems has fuelled a surge in demand for large capacity hard disk drives. This interest led Western Digital to create the WD Red NAS-optimised family of hard disk drives.

The WD Red family of NAS-optimised hard disk drives, with storage capacities from 750 GB all the way to 10 TB. Here is a specification comparison of the five key models:

They all share the following common features :

  • NAS Compatibility – Advanced firmware technology built into every WD Red drive, enables seamless integration, robust data protection and optimal performance for systems operating in NAS and RAID environments.
  • Exclusive NASware 3.0 Technology – WD’s exclusive NASware 3.0 technology further optimizes the WD Red for the NAS environment, allowing the WD Red to support small NAS systems with up to 8 bays!
  • 3D Active Balance Plus – This enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multidrive system, reduce the hard drive lifespan, and degrade the performance over time.[adrotate group=”2″]
  • Enhanced Reliability – With a 35% MTBF improvement over standard desktop drives, the WD Red drive is designed and manufactured to be a more reliable and robust solution.
  • Energy Efficient – Innovative technology reduces power consumption and lowers the operating temperature, resulting in a more reliable and affordable solution for always on 24×7 NAS environments.
  • Premium Support – Exclusively for WD Red drive customers, a free dedicated 24/7 support line is available in English. Other regional support hours vary.
  • Longer Warranty Coverage – The WD Red drive is backed by a 3-year limited warranty for greater peace of mind.

Now, let’s check out the 10TB WD Red (Lowest Price) hard disk drive!

 

A Quick Look At The 10TB WD Red

The 10 TB WD Red (Lowest Price) hard disk drive came in a sealed antistatic plastic pack. Notably, it lacked the usual sachet of desiccants. That’s because the drive is hermetically-sealed in the factory, and filled with helium. Also notable is their use of two gold-coloured screws to lock the PCB in place.

To remove the drive, just tear off the top or cut it open, and slide out the drive. Be sure to ground yourself before removing and handling the hard disk drive as static can damage it. In particular, you should try to avoid touching the exposed PCB located on the lower underside of the drive.

The 10TB WD Red NAS Drive

Despite featuring a hermetically-sealed chassis, the 10 TB WD Red (WD100EFAX) drive looks deceptively like any other 3.5″ hard disk drive. In fact, it even sports the same printed label on the top plate, with an uncovered PCB on the underside.

The label has a lot of important information, like the hard disk drive model, storage capacity as well as its date and place of manufacture. This particular drive was manufactured in Thailand on the 1st of April, 2017. You can also see that the drive uses the Advanced Format Technology to achieve its high storage density.

 

HelioSeal Technology

The 10 TB WD Red (WD100EFAX) NAS-optimised drive is one of the few hard disk drives in the market to feature the revolutionary HGST HelioSeal technology. It is hermetically sealed at the factory, and filled with helium.

Instead of a breather hole that is present in all “air-filled” hard disk drives, it has two sealed ports that are used to extract air from inside the chassis, and replacing it with helium.

Because helium is only 1/7th the density of “regular air”, it allows for less friction conferring the following benefits :

[adrotate group=”2″]
  • The lower friction reduces the amount of power required to spin the platters, reducing both energy costs and thermal output.
  • Internal turbulence is greatly reduced, which makes tracking more precise and reliable. This indirectly allows for greater areal density.
  • The lower power requirement and internal turbulence allow more platters and heads to be added in the same volume of space.
  • The completely sealed environment eliminates reliability issues that can occur if breather filters get clogged up with dirt.

The only things stopping helium-filled drives from becoming mainstream are the relatively high cost of helium, and the difficulty in sealing the drive.

 

SATA 6 Gb/s

This is a Serial ATA drive, with native support for SATA 6 Gb/s. However, it is backward-compatible so you will have no problem using it with older SATA 3 Gb/s controllers.

The SATA 6 Gb/s interface is necessary for optimal performance since the 10 TB WD Red (Lowest Price) NAS drive boasts a maximum sustained internal (platter-to-buffer) transfer rate of 210 MB/s, and a large and fast DDR3 SDRAM cache.

Like all Serial ATA drives, it comes the standard SATA data (left) and power (right) connectors and is hot-pluggable. That means you can connect and disconnect this hard disk drive to the server, computer or NAS while it’s still running.

What’s Under The PCB?

Western Digital has a penchant for keeping all surface-mounted components on the reverse side of the PCB – to prevent static damage and to allow for better cooling. The PCB is protected by a thin foam cutout on the chassis side, with a thermal pad to help transfer heat from the HDD controller to the hard disk drive chassis.

Unfortunately, we can’t make out the hard disk drive controller Western Digital used, but we can see that it uses the ST Microelectronics L7232 motor drive controller, which features their proprietary Smooth Drive pseudo-sinusoidal digital drive technology.

The 10 TB WD Red (Lowest Price) NAS drive boasts a large 256 MB SDRAM cache, courtesy of an EtronTech EM6GD16EWXC-12H chip. This is a DDR3-1600 SDRAM chip with 8 memory banks and timings of 11-11-11. This gives it a peak transfer rate of 400 MB/s.

Finally, the 10 TB WD Red (Lowest Price) NAS drive has two shock sensors that allow it to better detect shock and vibration events, and dynamically adjust the flying height of the read/write heads to avoid head crashes.

10 TB WD Red Usable Capacity

The 10 TB WD Red (WD100EFAX) NAS drive has an official formatted capacity of 10 terabytes. We checked that out by formatting it in NTFS using Microsoft Windows 7.

The actual formatted capacity was 10,000,695,029,760 bytes, which is about 695 MB higher than the official storage capacity. With about 494 MB allocated to the NTFS file system, the actual usable capacity was slightly above 10 TB.

 

10 TB WD Red Platter Profile

The platter profile of the 10 TB WD Red (WD100EFAX) NAS drive was pretty good. There appeared to be some use of replacement sectors, but nothing particularly significant.

We also compared its platter profile to that of the 6TB WD Red, which was the last WD Red drive we reviewed. We can see right away that the 10 TB WD Red (Lowest Price) uses higher density platters, which gave it a very high throughput.

In fact, the outermost tracks of the 6 TB WD Red only equalised the 10 TB WD Red at the 6.5 TB point. Even at its slowest tracks, the 10 TB WD Red was as fast as the 6 TB WD Red at its 5 GB point.

[adrotate group=”1″]

 

Maximum Surface Temperature

We monitored the surface temperature of seven hard disk drives during their benchmarks. The following chart shows their operating temperature range, from idle to maximum load. Please note that instead of giving you the absolute numbers, we are showing the temperature delta, which is the difference between the actual temperature and the ambient room temperature.

Despite packing 2 additional platters than the 6 TB WD Black, the 10 TB WD Red (Lowest Price) drive was significantly cooler at full load. It ran a little warmer than the 8 TB WD Gold – another helium-filled drive, but was cooler at idle.

This reduced thermal output (and power consumption) is a key advantage of helium-filled hard disk drives like the 10 TB WD Red drive. When used in large NAS systems with up to 8 drives running non-stop, the lower energy costs of running them, and keeping them cool, will be very significant.

Transfer Rate Range

This chart shows you the range of platter-to-buffer transfer rates from the innermost track to the outermost track. In other words, it shows you the range of disk transfer rates of the hard disk drives (from minimum to maximum).

The 10 TB WD Red NAS drive has an official peak throughput of 210 MB/s, which was confirmed by our tests. In fact, it actually peaked at 217 MB/s. While it was still slightly slower than the 6 TB WD Black, that puts it ahead of most of its competitors.

Both the 8 TB WD Gold and the 10 TB WD Red have 7 platters. The 10 TB WD Red (Lowest Price) use higher density 1.43 GB platters to compensate for the 8 TB WD Gold‘s higher 7200 RPM spindle speed. This proves yet again that HDD performance is not always about the spindle speed… 😉

 

Business Disk WinBench 99

Even though it’s not optimised for desktop applications, the 10 TB WD Red (WD100EFAX) NAS drive did very well in this benchmark, coming in faster than even the 6 TB WD Black.

Random Throughput

The small random reads and writes are the most important tests for applications that make a lot of random accesses, so those would be key performance indicators for drives that are used as boot or system drives, but not very important for NAS systems.

With the exception of small reads, the 10TB WD Red (Lowest Price) was far superior than the 6 TB WD Red in all other aspects. Most impressively, it was 3X faster at small writes, most likely due to its large, fast cache.

We are not sure what HDD controller Western Digital used for the 10TB WD Red (Lowest Price) NAS drive, but they appeared to have decided to focus on performance at the expense of CPU utilisation. This is not a problem for NAS systems because they have a processor that is dedicated to such operations. Such high CPU utilisation though means the 10 TB WD Red (WD100EFAX) would not make for a very good desktop drive.

Even in sequential accesses, the 10 TB WD Red (WD100EFAX) took up an excessive amount of CPU utilisation. Again, this is not a problem for NAS systems, but will be an issue for those who choose to use this drive in their desktop systems.

Our Verdict & Award

This is our second review of a helium-filled hard disk drive (after the 8 TB WD Gold), and we continue to be impressed. Even from its specifications alone, we can already see a significant reduction in power consumption and noise levels. These are not minor either.

The 10 TB WD Red (WD100EFAX) boasts 11% lower power consumption than the air-filled WD Red models at peak loads, and an astounding 46% lower power consumption during idle! It accomplished this despite packing 2-4 more platters than the other WD Red drives.

The platters of the 10 TB WD Red (WD100EFAX) still spin at a relatively sedate 5400 RPM, but they have a very high areal density, boasting a storage capacity of 1.43 GB per platter. This high areal density gave it a very high throughput, allowing it to beat even the 8 TB WD Gold, which has a spindle speed of 7200 RPM.

Our benchmarks show that it is one of the fastest hard disk drives in the market, beating even high-performance drives like the 6 TB WD Black. This is very impressive performance for a 5400 RPM drive that is optimised for NAS systems.

The downside though is its high CPU utilisation. This is not a problem if you intend to use it in a relatively new NAS system, but it may be a problem if you pack more than two of them in an old NAS system with a slow processor. The high CPU utilisation will also be an issue if you intend to use this drive in your desktop PC.

Despite the high CPU utilisation, its stellar performance deserves our Reviewer’s Choice Award. Congratulations, Western Digital!

The 8TB WD Gold Datacenter Drive (WD8002FRYZ) Review

WD Gold Datacenter Drives

On April 20, 2016, Western Digital launched the new WD Gold family of hard disk drives. These hard disk drives are designed for maximum performance and reliability in the highly demanding conditions of a datacenter. In fact, they are rated to handle workloads of up to 550 TB per year (1.5 TB per day), with a MTBF rating of up to 2.5 million hours!

Today, we are going to take a look at the 8TB Western Digital Gold hard disk drive. This is one of the two helium-filled WD Gold models to feature a hermetically-sealed chassis with an internal helium environment. That’s not what’s different though. For your convenience, we created a specification comparison of the WD Gold family of datacenter drives :

Unboxing The 8TB WD Gold Drive

The 8TB WD Gold (WD8002FRYZ) hard disk drive came in a sealed antistatic plastic pack. Notably, it lacked the usual sachet of desiccants. That’s because the drive is hermetically-sealed in the factory, and filled with helium. Also notable is their use of two gold-coloured screws to lock the PCB in place.

To remove the drive, just tear off the top or cut it open, and slide out the drive. Be sure to ground yourself before removing and handling the hard disk drive as static can damage it. In particular, you should try to avoid touching the exposed PCB located on the lower underside of the drive.

The 8TB WD Gold Datacenter Drive

Despite featuring a hermetically-sealed chassis, the 8TB WD Gold (WD8002FRYZ) datacenter drive looks deceptively like any other 3.5″ desktop hard disk drive. In fact, it has the same label on the top plate, with an uncovered PCB on the underside.

The label has a lot of important information, like the hard drive model, storage capacity as well as its date and place of manufacture. This particular drive was manufactured in Thailand on the 26th of March, 2016. You can also see that the drive uses the Advanced Format Technology to achieve its high storage density.

 

HelioSeal Technology

The 8TB WD Gold datacenter drive is one of the few hard disk drives in the market to feature the revolutionary HGST HelioSeal technology. It is hermetically sealed at the factory, and filled with helium. The hole, which normally serves as the breather hole in a normal “air-filled” hard disk drive, is likely the port through which the air is extracted and replaced with helium.

Because helium is only 1/7th the density of “regular air”, it allows for less friction conferring the following benefits :

  • The lower friction reduces the amount of power required to spin the platters, reducing both energy costs and thermal output.
  • Internal turbulence is greatly reduced, which makes tracking more precise and reliable. This indirectly allows for greater areal density.
  • The lower power requirement and internal turbulence allow more platters and heads to be added in the same volume of space.
  • The completely sealed environment eliminates reliability issues that can occur if breather filters get clogged up with dirt.

The only things stopping helium-filled drives from becoming mainstream are the relatively high cost of helium, and the difficulty in sealing the drive.

 

Media Caching Technology

This feature was mentioned only perfunctorily in the Western Digital press release, which led many writers to assume that they added a NAND flash cache, like the ones used in SSHDs (examples : 4TB WD Blue SSHD, 1TB WD Blue SSHD). Unfortunately, that’s not true.

The media caching technology used in the WD Gold datacenter drives are also a HGST technology, like HelioSeal. It doesn’t use any additional components, just the existing SDRAM cache and the hard disk drive platters. This is how it works :

[adrotate group=”2″]
  • Small media cache areas are created in regular intervals across the platters. These are only visible to the drive controller, and are hidden to the computer and operating system.
  • Data written to the SDRAM cache are combined and regularly written down to the nearest media cache areas at a higher internal queue depth.
  • These dispersed media cache areas boost write performance by greatly reducing head movements as data is written to the drive.
  • The write data is simultaneously de-staged, which eliminates burst activity and their impact on reads from the platters.
  • In the event of a sudden power-off event, the media cache areas is used to quickly restore the SDRAM cache.

Generally, the media caching technology increases random write performance with a slight boost in read performance.

SATA 6 Gb/s

This is a Serial ATA drive, with native support for SATA 6 Gb/s. However, it is backward-compatible so you will have no problem using it with older SATA 3 Gb/s controllers.

The SATA 6 Gb/s interface is necessary for optimal performance since the 8TB WD Gold datacenter drive boasts a maximum sustained internal (platter-to-buffer) transfer rate of 205 MB/s, and a large and fast DDR3 SDRAM cache.

Like all Serial ATA drives, it comes the standard SATA data (left) and power (right) connectors and is hot-pluggable. That means you can connect and disconnect this hard disk drive to the server, computer or NAS while it’s still running.

 

What’s Under The PCB?

Western Digital has a penchant for keeping all surface-mounted components on the reverse side of the PCB – to prevent static damage and to allow for better cooling. The PCB is protected by a thin foam cutout on the chassis side, with a thermal pad to help transfer heat from the HDD controller to the hard disk drive chassis.

The 8TB WD Gold datacenter drive uses the LSI 7101B hard disk drive controller, and the ST Microelectronics L7229 motor drive controller, which features their proprietary Smooth Drive pseudo-sinusoidal digital drive technology.

[adrotate group=”1″]

The 8TB WD Gold datacenter drive boasts a large 128 MB SDRAM cache, courtesy of a Samsung K4B1G1646G-BCK0 chip. This is a DDR3-1600 SDRAM chip with 8 memory banks and timings of 11-11-11. This gives it a peak transfer rate of 400 MB/s.

Finally, the 8TB WD Gold datacenter drive has two shock sensors that allow it to better detect shock and vibration events, and dynamically adjust the flying height of the read/write heads to avoid head crashes.

Testing Methodology

 

Usable Capacity

The WD Gold 8TB datacenter drive has an official formatted capacity of 8,001,563,222,016 bytes. We checked that out by formatting it in NTFS using Microsoft Windows 7.

The actual formatted capacity was 8,001,427,599,360 bytes, which is about 136 MB lower than the official storage capacity. With about 338 MB allocated to the NTFS file system, the actual usable capacity remained slightly above 8 TB.

 

Platter Profile

As expected from a premium, datacenter-grade hard disk drive, the platter profile of the WD Gold 8TB datacenter drive was phenomenal. There were absolutely zero dips in throughput that would signify a significant use of replacement sectors. Lots of them would be evidence of poor platter quality.

We also compared its platter profile to that of the 6TB WD Black – Western Digital’s top-of-the-line desktop hard disk drive. We can see that the denser platters allow the 6TB WD Black to achieve a higher throughput initially, but the 8TB WD Gold equalised it at around the 3.5TB point.

Thereafter, the 8TB WD Gold was faster. In fact, at the 6TB point, the 8TB WD Gold was about 36% faster than the 6TB WD Black.

[adrotate group=”1″]

 

Maximum Surface Temperature

We monitored the surface temperature of seven hard disk drives during their benchmarks. The following chart shows their operating temperature range, from idle to maximum load. Please note that instead of giving you the absolute numbers, we are showing the temperature delta, which is the difference between the actual temperature and the ambient room temperature.

Despite packing 2 additional platters than the 6TB WD Black, the 8TB WD Gold drive was significantly cooler at full load. In fact, it ran cooler than the 4 TB WD Black Gen. 2, and the 4 TB WD Red Pro drives!

This reduced thermal output (and power consumption) is a key advantage of helium-filled hard disk drives like the 8TB WD Gold drive. When deployed in the hundreds or thousands in a datacenter, the lower energy costs of running them, and keeping them cool, will be very significant.

Transfer Rate Range

This chart shows you the range of platter-to-buffer transfer rates from the innermost track to the outermost track. In other words, it shows you the range of disk transfer rates of the hard disk drives (from minimum to maximum).

The 8TB WD Gold drive has an official peak throughput of 205 MB/s, which was confirmed by our tests. In fact, it actually peaked at 209 MB/s. While that puts it ahead of most of the competition, it was still slower than the 6TB WD Black.

This is because the 8TB WD Gold uses platters with slightly lower areal density (about 1,142 GB per platter) than the 6TB WD Black, which boasts 1,200 GB per platter.

 

Business Disk WinBench 99

The 8TB WD Gold datacenter drive is not optimised for desktop applications, so it’s no wonder that it isn’t the fastest drive in this test. Even so, the 8TB Gold datacenter drive did reasonably well, coming within 12% of the 6TB WD Black.

Check out the incredible boost in the random write speed, especially for small random writes. The 8TB WD Gold delivered almost double the performance of the 6TB WD Black drive in small random writes, and a 10% boost in performance in large random writes.

This is the key advantage of the HGST media caching technology that Western Digital included into the 8TB WD Gold. This is a tremendous performance advantage in file storage servers that serve hundreds or thousands of users.

4 KB Write 53.91 MB/s 84.54 MB/s – 36.2%

The WD Gold 8TB datacenter drive uses less dense platters, so its sequential throughput is understandably lower than that of the 6TB Western Digital Black. That would account for about a 5% deficit in performance, with the rest due to the drive being optimised for random writes.

In fact, we can see here that the HGST media caching technology actually results in a large drop in small sequential write performance.

IOPS Scaling (Sequential)

In these tests, we tested the drive’s ability to tackle multiple input/output operations. Again, we compared the 8 TB Western Digital Gold to the 6 TB Western Digital Black – the fastest desktop-grade hard disk drive in Western Digital’s arsenal. For more performance comparisons, please take a look at The Hard Disk Drive Performance Comparison Guide.

It is obvious that the “price” for almost doubling the small random write performance is poorer sequential read and write performance.

Our Verdict & Award

This is our first review of a helium-filled hard disk drive, and we are very impressed. Even from its specifications alone, we can already see a significant reduction in power consumption and noise levels. These are not minor either.

The helium-filled 8TB WD Gold (WD8002FRYZ) datacenter drive boasts 22% lower power consumption, and is half as loud as the air-filled WD Gold models when they are not seeking. We confirmed these claims during our tests, noting how quiet it was, and how it ran almost as cool as 5400 RPM hard disk drives despite packing 3-4 additional platters than the drives we compared it to!

The 8TB WD Gold datacenter drive achieves its tremendous storage capacity, not by increasing areal density, but by packing 2 additional platters. This is only made possible by filling it with helium, reducing turbulence and friction.

While this allows Western Digital to quickly increase storage capacity, it doesn’t help with its performance. That’s why it was slightly slower than top-of-the-line desktop drives like the 6TB Western Digital Black. That doesn’t meant that the 8TB WD Gold datacenter drive is a slow drive. Far from it. It is a fast drive, but not in the way we expect.

The 8TB WD Gold datacenter drive is optimised for datacenter applications. Hence, it features the HGST media caching technology which trades sequential write performance for a big boost in its small random write performance. This is not a very useful trade-off for desktop users, but a big boon to servers that handle hundreds or thousands of users.

The 8TB WD Gold datacenter drive would be overkill for home or office users, even for NAS applications. But there is no doubt that it would offer a big boost in performance and a tremendous reduction in TCO (Total Cost of Ownership), considering its significantly lower power consumption and thermal output per TB of storage. In light of that, we think the WD Gold 8TB datacenter drive deserves no less than our Reviewer’s Choice Award! Congratulations, Western Digital!

The 1TB WD Blue SSD (WDS100T1B0A) Review

The new WD Blue and WD Green solid state drives are the first product of Western Digital’s acquisition of SanDisk in May 2016. However, it was not Western Digital’s first acquisition of a solid state manufacturer, or even their first solid state drive.

Western Digital acquired the SSD manufacturer, SiliconSystems and released the WD SiliconDrive family in 2009. However, the SiliconDrive family didn’t gain much traction. The SanDisk acquisition though was much larger and far more substantial. Western Digital not only gained access to a wide array of SSD and NAND intellectual property, they now have a substantial and stable NAND flash supply.

Today, we are going to take a look at their top-of-the-line solid state drive –  the 1TB WD Blue SSD (WDS100T1B0A), which features SanDisk’s second-generation 15 nm TLC NAND technology. Check it out!

 

The WD Blue SSD Family

The new WD Blue SSD family will offer 1 TB, 500 GB and 250 GB models, each available in either the 2.5″ or the M.2 form factor. Here is a specification comparison of the three main models :

The 1TB WD Blue SSD

The 1TB WD Blue SSD (WDS100T1B0A) looks like any other 2.5″ slim hard disk drive. It was, after all, built to conform to the 2.5″ form factor, allowing it to easily replace any 2.5″ hard disk drive with a height of 7 mm. But there’s no doubt about its solid state nature when you pick it up – it’s very light!

The label on the underside has a lot of important information, like the model and serial numbers in case you need to RMA it. The label also lists interesting details like the date and place of manufacture. This particular drive was manufactured in China on 9 September 2016.

As it only serves to protect the NAND chips, SSD controller and circuit board inside from static damage, the case is made from plastic. In fact, it will sound hollow when you tap on it because the SSD internally does not take up much space.

 

SATA 6 Gb/s Interface

The 1TB WD Blue SSD is a Serial ATA drive, with native support for SATA 6 Gb/s interface. It is backward-compatible, so you will have no problem using it with older SATA 3 Gb/s controllers. However, the faster SATA 6 Gb/s interface is necessary for optimal performance because this SSD is capable of a peak transfer rate of 545 MB/s.

Like all Serial ATA drives, it comes with the standard SATA data (left) and power (right) connectors, and is hot-pluggable. That means you can connect and disconnect this solid state drive while the PC is still running. There is no jumper block, because there’s really nothing for you to set. It’s just plug and play!

 

The Marvell 88SS1074 SSD Controller

The 1TB WD Blue SSD uses the Marvell 88SS1074 SSD controller, which boasts the following key features :

  • Supports up to 4 NAND channels, with up to 8 NAND chips per channel
  • Features Marvell’s third-generation NANDEdge low-density parity check (LDPC) technology
  • Supports SATA 3.2 (6.0 Gbps)
  • Toggle 2 and ONFI2 support at up to 400 MT/s
  • Integrated DEVSLP (Device Sleep) mode for low power support
  • Supports 256-bit AES hardware encryption
  • Built on 28 nm CMOS process

The Marvell NANDEdge LDPC technology allows for reliable on-the-fly error correction of the 3-bit TLC flash memory, with minimal impact on latency, performance and power consumption.

However, the Marvell 88SS1074 is likely to fall short in sustained throughput, because it only supports 4 NAND channels. Competing controllers like the Phison S10, for example, boast 8 NAND channels, allowing twice as many NAND chips to be accessed simultaneously.

 

The SanDisk TLC Flash Memory

To keep costs low, the 1TB WD Blue SSD uses TLC (Triple Level Cell) flash memory chips, where each cell holds 3-bits. These are SanDisk second-generation planar TLC chips, built on the 15 nm process. There are a total of eight of these TLC flash memory chips, each with a capacity of 128 GB.

 

The Micron DDR3L SDRAM Cache

The 1TB WD Blue SSD has a large 1 GB write combine cache, courtesy of two Micron MT41K512M8RG-107 chips. These are DDR3L SDRAM chips with an effective clock rate of 1866 MHz (DDR), a voltage of 1.35 V, and a storage capacity of 512 MB.

This large SDRAM cache allows the WD Blue SSD to mitigate the TLC flash memory’s inherently poor write performance. It also allows writes to the SSD to be combined, reducing wear on the flash memory cells and extending their lifespan.

SSD Endurance

The 1TB WD Blue SSD is rated for a lifetime write lifespan of 400 TBW (Terabytes Written). That does not seem like a lot (equal to overwriting the drive just 400 times), but it is considered enterprise-grade endurance. Many consumer-grade SSDs of equivalent capacity are rated at around 75-100 TBW.

Based on a typical consumer DWPD (Drive Writes Per Day) of 20 GB per day, this 1TB WD Blue will last at least 54 years. Please note that this long lifespan is due to the large capacity. The 500 GB and 250 GB WD Blue SSDs are rated at 200 TBW and 100 TBW respectively. That corresponds to an estimated lifespan of 27 years and 13.5 years respectively.

Like all other current SSDs, the 1TB WD Blue SSD comes with certain features to help extend its lifespan :

Wear Levelling

Unlike hard disk drives, flash-based SSDs write and overwrite data in large blocks of 512 KB to 1 MB in size. Even if you only need to write one byte of data, it has to erase and overwrite an entire block. This causes a lot of wear on the memory cells and greatly reduces their lifespan.

To help extend the lifespan of the drive, SSDs perform wear levelling by spreading the writes, so that the flash memory cells have equal wear. The lifespan of the memory cells remain unchanged, but it prevents some of them from failing earlier due to excessive wear.

Write Combine Cache

SSDs also use a write buffer to temporarily store and combine the writes before they are actually written to the flash memory. This reduces the number of block erases required, and consequently, extends the lifespan of the flash memory cells.

The 1TB WD Blue SSD boasts a large 1 GB DDR3L memory cache, which should help to really extend the limited lifespan of the TLC flash memory. This allows the 1TB WD Blue to get away with a very small amount of “over-provisioned” space.

TRIM

Current SSDs support the TRIM command, otherwise known as the ATA8-ACS-2 DATA SET MANAGEMENT command. Operating systems that support TRIM (e.g. Microsoft Windows 7) will notify the SSD when data blocks are deleted in the file system. This allows the SSD to perform garbage collection in the background – internally erasing the affected blocks so that they are ready to be written to.

Without the TRIM command, the SSD will not know when a block of data has been deleted by the operating system. When new data is written to the same block of data, it will force the SSD to perform the time-consuming read-erase-modify-write cycle, which not only cripples performance but also increases wear on the affected memory cells.

Multi-Stream

This is a new SSD technology that was introduced in May 2015, as part of the T10 SCSI Standard. Multi-stream greatly improves performance and extends lifespan by reducing or even eliminating garbage collection.

It achieves this by marking data writes that are associated with one another, or have a similar lifetime, with a unique stream ID. This allows the SSD controller to pack all data writes with the same stream ID into the same block.

When the operating system deletes data, it is likely that they are all packed into the same block. If the block has not been written to the SSD, then this eliminates the pending write operation completely. If the block has been written to the SSD, then this would only require that single block to be erased, instead of multiple blocks (which would happen if the data was not all packed into the same block).

 

SSD Maintenance

First of all, you should never, ever defragment solid state drives. Spatial fragmentation of data on the SSD has no effect on its performance. Fragmented data are accessed as quickly as nicely-packed blocks, so it’s pointless to defragment the data blocks. Doing so will only reduce the lifespan of the flash memory cells by putting them under additional wear.

Remember – TLC flash memory will only last about 1,000 erase/write cycles. You will want to minimise the number of times each flash memory cell is erased.

[adrotate banner=”4″]

You should also use an operating system that supports the TRIM command. If you are using one of the following operating systems, then you have nothing to worry about :

  • Microsoft Windows 7, or better
  • Microsoft Windows Server 2008 R2, or better
  • Linux 2.6.33, or better
  • FreeBSD 8.2, or better
  • Mac OS X Snow Leopard, or better

If not, you should consider upgrading your operating system. Otherwise, you will need to perform manual garbage collection on a regular basis, either using a manufacturer utility, or newer defragmentation software that specifically supports solid state drives. Basically, these utilities will retrieve the list of free blocks from the operating system’s file system and pass it to the SSD in the form of TRIM commands, so that it will know which blocks to erase internally.

Western Digital does not provide such a utility for their WD Blue SSDs, so if you are using an older operating system, you will need to use a third-party SSD optimisation software. Note that those software are not necessary if you are using an operating system that supports TRIM.

Testing Methodology

 

Over-Provisioning & Usable Capacity

This WD Blue SSD has a maximum storage capacity of 1,024 GB, courtesy of eight 128 GB Micron NAND chips. Of that, a mere 24 GB has been set aside for garbage collection, wear levelling and replacement of failing blocks.

Ordinarily, the limited 2.4% over-provisioning may impact long-term performance and lifespan. However, it appears that Western Digital has opted to mitigate that using a large 1 GB DDR3L SDRAM cache.

After it is formatted in NTFS, the actual formatted capacity is 1,000,202,039,296 bytes. This is slightly (202 MB) more than the official formatted capacity of 1,000 GB.

With about 124 MB of space allocated to the NTFS file system, the actual usable capacity is just above 1,000 GB.

Transfer Rate Range

This chart shows you the range of memory cell-to-controller transfer rates for SSDs, or the range of platter-to-buffer transfer rates from the innermost track to the outermost track in HDDs.

Despite boasting an official peak transfer rate of 545 MB/s, our tests show that the sustained transfer rate of the 1TB WD Blue SSD is much slower – between 230 and 249 MB/s. This makes it significantly slower than the other SSDs in this comparison. It is important to note though that the 1TB WD Blue SSD remains much faster than even top-of-the-line hard disk drives like the 1TB WD VelociRaptor.

4 KB Read 24.93 MB/s 27.57 MB/s – 9.6%
4 KB Write 53.31 MB/s 53.52 MB/s

The small random reads and writes are the most important tests for applications that make a lot of random accesses, so these would be key performance indicators for SSDs that are often used as boot drives.

The 1TB WD Blue SSD held up well in small reads and writes, matching the 240 GB HyperX Savage SSD in writes, and coming in just 10% slower in reads. The large SDRAM cache seems to be doing its job very well.

However, it was much slower when it came to large reads and writes. This is due to the TLC the Phison S10 controller used in the HyperX Savage has twice the NAND channels of the WD Blue’s Marvell 88SS1074 controller.

4 KB Read 63.35 MB/s 24.89 MB/s + 154.5%
4 KB Write 59.15 MB/s 53.65 MB/s + 10.3%

The sequential read and write performance indicators determine how fast you can copy and move files. This is also important in determining how fast you can launch an application or game.

The 1TB WD Blue SSD did very well when the sequential reads and writes were small. It was particular good at small sequential reads. However, when it came to large sequential accesses, the WD Blue’s limited NAND channels came into play… giving it half the throughput of the HyperX Savage SSD.

ATTO Disk Benchmark

ATTO Disk Benchmark is a free benchmark that allows you to compare the performance of solid state drives using a variety of transfer sizes. It also allows us to determine if the SSD performs data compression to improve performance, and extend lifespan.

 

I/O Comparison

Results Compressible Data Non-Compressible Data
Minimum Maximum Minimum Maximum
Read Speed 11.3 MB/s 246.8 MB/s 11.3 MB/s 249.7 MB/s
Write Speed 10.4 MB/s 269.5 MB/s 10.6 MB/s 269.5 MB/s

The Marvell 88SS1074 controller does not perform any data compression, which is why the performance results are the same for both compressible and non-compressible data. The 1TB WD Blue SSD reached its peak transfer rate with a block size of 1 MB.

Results Compressible Data Non-Compressible Data
Minimum Maximum Minimum Maximum
Read Speed 26.6 MB/s 286 2 MB/s 26.6 MB/s 285.6 MB/s
Write Speed 24.5 MB/s 273.9 MB/s 24.8 MB/s 274.5 MB/s

With just 8 simultaneous transactions, the 1TB WD Blue SSD reached its peak transfer rate with a block size of 64 KB.

 

Our Verdict

The 1TB WD Blue SSD offers extremely quick random access times like other modern solid state drives. But it is no race car. Due to its 4-channel design, it was half as fast as comparable SSDs at transferring large files. On the other hand, it offers a tremendous amount of space at an affordable price point, and boasts enterprise-class endurance levels. So what does this mean for you, the user?

 

If you are looking for the absolute fastest SSD in the market, then the 1TB WD Blue SSD is not for you. You can find much faster SSDs in the market, albeit at much higher price points.

But if you are looking for a decent solid state drive with a large storage capacity, and don’t want to sell an arm and a leg for it, the 1TB WD Blue SSD is worth considering. More so if you want something that will last you for many years to come.

The 1TB WD Blue SSD works well as a boot drive, booting up the operating system and applications much faster than any hard disk drive can. It may be much slower than comparable SSDs in certain benchmarks but in real life, it will only mean the operating system and applications start up a bit slower. In fact, you are unlikely to notice any difference unless you compare two systems side-by-side.

The WD Blue SSD‘s large storage capacity is a great boon to laptop users who cannot add a second hard disk drive for more storage. It would obviate the need to use a portable hard disk drive for extra storage. It also allows for an intriguing possibility – install it into a USB enclosure and you have a spacious portable drive that is impervious to shock and vibration!

WD Gold – The Gold Standard In HDD Technology

Hard disk drives have evolved into many distinct families to cater to different requirements – performance, low cost storageNAS, surveillance, etc. They often emphasise one attribute over others, to meet the requirements of their target market, while keeping costs low. But what if you wanted nothing but the best in hard disk drive technology? That’s where datacenter-grade hard disk drives like WD Gold come in.

Qualified for nearline storage use in datacenters, datacenter hard disk drives like WD Gold (Lowest Price) are designed to offer high storage capacities at maximum performance and reliability while operating continuously 24 hours a day. Virtually no expense is spared in making these drives the gold standard in HDD technology. That is likely why Western Digital gave their datacenter drives the WD Gold moniker.

Let’s take a quick look at why the WD Gold drives are the best hard disk drives in the industry.

 

Industry-Leading Storage Capacity

The WD Gold (lowest price on Amazon) is available in storage capacities from just 1 TB, all the way to the industry-leading storage capacity of 10 TB.

 

Constant Peak Performance

Unlike desktop-grade performance hard disk drives, the WD Gold (Lowest Price) is designed for peak performance at all times. While they may be classified as datacenter hard disk drives, the WD Gold drives can certainly be used in any desktop or consumer system.

On top of a 7,200 RPM spindle speed, the WD Gold also boasts a large (128 MB or 256 MB) SDRAM cache, and the HGST Media Caching Technology. They both help to sustain a high read and write throughput from the WD Gold drives.

 

Less Noise & Vibration, Lower Power Consumption

[adrotate banner=”4″]

The WD Gold (Lowest Price) is built around the revolutionary HGST HelioSeal technology, which seals the drive and fills it with helium. Because it is only 1/7th the density of “regular air”, helium imparts the following advantages to the WD Gold drives :

  • less friction for the spinning platters, reducing power consumption and thermal output
  • less internal turbulence, allowing for more reliable head-to-platter tracking
  • more capacity because more platters and drive heads can be fitted in the same volume of space
  • the completely sealed environment eliminates reliability issues from outside contaminants

 

24×7 Reliability

The WD Gold (Lowest Price) drives are designed to handle high workloads (up to 550 TB per year) continuously for years. They boast a phenomenal mean time before failure (MTBF) of 2.5 million hours. That is partly due to vibration control technologies like the Enhanced RAFF (Rotary Acceleration Feed Forward) technology, and extensive testing.

To ensure the best possible 24×7 reliability, the WD Gold (Lowest Price) drives undergo rigorous tests in the factory before they are certified for use. They are also extensively tested with a wide variety of systems, controllers and adapters to ensure maximum compatibility and ease-of-installation into any storage system.

 

Our Choice

The WD Gold (lowest price on Amazon) is designed for the most arduous and demanding conditions in the datacenter, but it doesn’t mean you can’t use it in a less-demanding desktop environment. In fact, tech enthusiasts who want nothing but the best hard disk drive and can afford to pay for the bespoke quality, can buy and use the WD Gold in their desktops or even NAS systems!

We tested the WD Gold extensively in our 10-page review, and came away very impressed with its performance. It was not just fast, it was also quiet and it ran really cool. That is why we awarded it our Reviewer’s Choice Award.

Now, the lower cost of ownership may not matter much for a desktop user with a couple of WD Gold drives, but it matters a great deal if you are running a datacenter with tens of thousands of servers. The WD Gold (Lowest Price) drives will not just reduce downtime from drive failures, they will greatly reduce the TCO (Total Cost of Ownership).

Mainstream Hard Disk Drives Keep Getting Better

Hard disk drives have become so commoditised that most users assume that one hard disk drive is no different from another. That’s not true, of course, because there are performance-grade drives, NAS-optimised drives, and even surveillance hard disk drives. Even mainstream hard disk drives have seen remarkable improvements in reliability and performance over the years.

 

Mainstream Hard Disk Drives In The Past

The hard disk drive industry is highly competitive, with many manufacturers competing for the same piece of pie. Hence, mainstream hard disk drives tend to be developed with cost in mind.

As a general rule, they tend to use older technologies, have lower storage capacities, lower performance, and shorter warranties.

 

Less Competition, But Better Drives

Over the years, hard disk drive manufacturers have fallen, merged, or been bought up by their rivals. Today, only three hard disk drive manufacturers remain – Western Digital, Seagate and Toshiba.

Paradoxically, the reduced competition was actually good for the consumer. There was less pressure to compete solely on price. This allowed better mainstream hard disk drives to be developed.

 

Mainstream Hard Disk Drives Today

Today, mainstream hard disk drives are at the forefront of hard disk drive technologies. Even the most basic models feature the latest interface, platter technology and come with large caches for higher performance.

The newer SSHD (Solid State Hybrid Drive) models integrate flash memory technology to offer SSD-like performance, with large storage capacities and much more affordable prices.

Mainstream hard disk drives are also more reliable, boasting the latest data protection features. That’s why manufacturers offer longer warranties today, with most offering 2 years warranty, instead of just 1 year.

 

WD Blue Mainstream Hard Disk Drives

The most popular mainstream hard disk drives in the market today are arguable the WD Blue hard disk drives from Western Digital. Designed for mainstream usage patterns, the WD Blue drives are highly affordable yet boast features like :

  • NoTouch Ramp Load Technology : The drive heads are kept off the disk surface when the drive is idle or not running, to prevent damage to the platters if the drive is dropped or knocked.
  • Data LifeGuard : Advanced algorithms in the firmware that monitor your drive continuously to alert you of any impending failures.
  • IntelliSeek : The drive automatically adjusts its optimum seek speeds to lower power consumption, noise and vibration.

Western Digital offers the WD Blue hard disk drives in a wide variety of storage capacities to suit every need and budget.

[adrotate banner=”4″]

For users who want a boost in performance without paying top dollar for a solid state drive, Western Digital even offers two WD Blue solid state hybrid drive (SSHD) models :

These WD Blue SSHDs are basically WD Blue hard disk drives enhanced with a flash memory cache :

  • NAND Flash Technology : WD Blue SSHDs come with 8 GB of NAND flash memory to perform up to 4-5X faster than traditional 5400 RPM hard disk drives.
  • Self-Learning Technology : Using an advanced set of algorithms, WD Blue SSHDs continuously track data usage to prioritise frequently-used data. It can adapt, learn and optimise itself as new applications and data requests change over time.

Thanks to the flash memory cache, the WD Blue SSHDs offer SSD-like performance, with a large storage capacity at much lower prices than solid state drives.
