Kingston DC500 SSDs Are Now Certified VMware Ready!

Kingston DC500 SSDs Are Now Certified VMware Ready!

Kingston Technology just announced that their DC500 enterprise-grade SSDs are now certified VMware Ready. Find out what this means!

 

Kingston DC500 SSDs Are Now Certified VMware Ready!

After the VMware Ready validation process, the Kingston DC500 family of enterprise SSDs are now certified for VMware vSAN and vSphere in production environments.

The Kingston DC500 family of enterprise SSDs had earlier been validated by NAS providers like QNAP and Synology, but this is their first enterprise-class validation.

This gives their enterprise clients assurance that the Kingston DC500 SSDs can be deployed in production environments without worry.

The Kingston DC500 drives have been tuned using comprehensive QoS test scripts developed in-house that measure IO and latency patterns at varying block sizes and queue depths. This allows them to deliver low latency out to six 9s (99.9999 percent) of consistency while delivering high throughput and predictable IO.

The VMware Ready program is a co-branding benefit of the VMware Technology Alliance Partner (TAP) program that makes it easy for customers to identify partner products certified to work with VMware cloud infrastructure.

 

The Kingston DC500 SSD Family

The Kingston DC500 SSD family consists of two models – DC500R and DC500M that are tuned for different use cases :

Kingston DC500R : Read-Centric SSD

The Kingston DC500R is highly optimised for read-centric workloads, delivering high I/O speeds and response times at lower price points than write-intensive SSDs.

Kingston DC500M : Mixed-Use SSD

The Kingston DC500M, on the other hand, is tuned for mixed-use workloads which demand a mix of read and write operations. It offers greater write endurance with strict performance consistency for datacenters.

Kingston DC500 Common Features

Both Kingston DC500R and DC500M SSDs incorporate end-to-end data path protection, which guarantee that all data will be written to the SSD and is protected against transient errors.

They also include on-board Power-Loss Protection (PLP) using tantalum capacitors. This ensures that data-in-flight is written to the flash memory in the event of unexpected power loss. The PLP also ensures that the drives’ mapping table (FTL) is updated before the drive powers down.

These safeguards reduce the risk of data loss, and ensure that the drive will initialise properly when the server powers up again.

Intel Optane Memory H10 With QLC 3D NAND Revealed!

Intel just revealed Optane Memory H10, which combines Optane Memory with QLC 3D NAND storage! Here is a quick primer on the new H10 storage solution!

 

Intel Optane Memory H10 With QLC 3D NAND Storage!

Intel Optane Memory H10 combines Optane Memory with QLC 3D NAND storage on a single M.2 module to produce better responsiveness and storage capacity.

This tight integration allows both Optane Memory and a solid state drive to be added into thin and light notebooks, as well as space-constrained desktop form factors such as All-in-One PCs and mini PCs.

This eliminates the need for a secondary storage device, while offering a higher level of performance, compared to traditional Triple Level Cell (TLC) 3D NAND SSDs.

 

Intel Optane Memory H10 Benefits

The Intel Optane Memory H10 allows space-constrained designs to benefit from the performance boost from Optane Memory while enjoying a large, affordable storage capacity courtesy of Intel QLC 3D NAND.

When compared to a standalone TLC 3D NAND SSD system, Intel claims the H10 will offer these benefits :

  • Documents will launch 2X faster while multitasking
  • Games will launch 60% faster while multitasking
  • Media files will open up to 90% faster while multitasking

 

Intel Optane Memory H10 Models

Intel will offer these H10 configurations :

  • 16 GB Optane Memory + 256 GB QLC 3D NAND storage
  • 32 GB Optane Memory + 512 GB QLC 3D NAND storage
  • 32 GB Optane Memory + 1 TB GB QLC 3D NAND storage

The first systems will be available through OEMs such as Dell, HP, ASUS, Acer and others.

The 512 GB GIGABYTE M.2 SSD Revealed!

GIGABYTE just revealed their 512 GB GIGABYTE M.2 SSD, an affordable solid state storage solution for the mainstream market. Learn more about GIGABYTE’s latest M.2 solid state drive!

 

The 512 GB GIGABYTE M.2 2280 SSD Revealed!

Based on the NVMe architecture, the 512 GB GIGABYTE M.2 SSD utilises PCIe Gen3 x2 lanes to deliver higher bandwidth and transfer speeds compared to the traditional SATA interface. Like the earlier 128 GB and 256 GB models, the 512 GB GIGABYTE M.2 SSD supports TRIM and S.M.A.R.T technologies.

The 512 GB GIGABYTE M.2 SSD is built around TLC flash memory, with Host Memory Buffer (HMB) to improve performance at a more affordable price point.

 

Why PCIe x2, Not PCIe x4?

With reduced SSD prices in recent years, many users have made the transition from SATA devices to M.2 devices. Despite the upgrade, storage performance from their M.2 SSDs is often bottlenecked by the utilization of SATA 6Gb/s lanes on their storage devices.

The SATA 6Gb/s interface cannot match the read/write speeds of the SSDs, holding back their storage devices. NVMe based storage devices that utilize PCIe Gen3 lanes circumvent this issue but these devices usually come with PCIe Gen3 x4 lanes which makes them significantly more expensive.

While users are looking for better performance, NVMe based PCIe Gen3 x4 solid state drives are expensive. GIGABYTE M.2 SSD is based on NVMe architecture but uses PCIe Gen3 x2 lanes to reduce cost, while using Host Buffer Memory (HMB) to maximise performance.

HMB technology uses system memory to cache and improve the SSD‘s performance. This eliminates the need for dedicated cache memory, allowing GIGABYTE to keep costs low.

 

GIGABYTE M.2 SSD Price + Availability

The GIGABYTE M.2 SSD series comes with a 3 year warranty, and three capacity sizes of 128GB, 256GB and the newly-announced 512GB. Here are some direct purchase links (with prices accurate as of 24 December 2018) :

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 Profile

We compared the 1TB WD Blue 3D NAND SSD (Price Check) to the 1TB WD Blue SSD. As you can see, it has a sustained throughput of about 378 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 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

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 1TB SanDisk Ultra 3D SSD (SDSSDH3-1T00) Review

The 1TB SanDisk Ultra 3D SSD is the first SanDisk solid state drive to feature their 64-layer 3D NAND technology that delivers higher storage capacities, performance and endurance, with lower power consumption. Let’s see if the 1TB SanDisk Ultra 3D SSD delivers on that promise!

 

The SanDisk Ultra 3D SSD Family

The SanDisk Ultra 3D SSD family consists of four models built upon the same technology. They mainly differ in storage capacities, with some performance characteristics. Here’s a table comparing their key specifications :

The 1TB SanDisk Ultra 3D SSD Up Close!

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

The 1TB SanDisk Ultra 3D 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 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.

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!

Fixed Disk Boot Sector – The BIOS Optimization Guide

Fixed Disk Boot Sector

Common Options : Normal, Write Protect

 

Quick Review

The Fixed Disk Boot Sector BIOS feature provides rudimentary anti-virus protection by write-protecting the boot sector.

If this feature is enabled, the BIOS will block any attempt to write to the boot sector and flash a warning message. This protects the system from boot sector viruses. Please note that it offers no protection against other types of viruses.

If this feature is disabled, the BIOS will not block any writes to the boot sector.

This feature can cause problems with software that need to write to the boot sector. One good example is the installation routine of all versions of Microsoft Windows, from Windows 95 onwards. When enabled, this feature causes the installation routine to fail.

Many hard drive diagnostic utilities that access the boot sector can also trigger the system halt and error message as well. Therefore, you should disable this feature before running such utilities, or when you intend to install a new operating system.

IDE Detect Time Out – The BIOS Optimization Guide

IDE Detect Time Out

Common Options : 0 to 15 or 0 to 30, in 1 second steps

 

Quick Review

Motherboards are capable of booting up much faster these days, with the initialization of IDE devices now take place much earlier. Unfortunately, this also means that some older IDE drives will not be able to spin up in time to be initialized! When this happens, the BIOS will not be able to detect those IDE drives and make them available to the operating system even though there’s nothing wrong with them.

This is where the IDE Detect Time Out BIOS feature comes in. It allows you to force the BIOS to delay the initialization of IDE devices for up to 30 seconds (although some BIOSes allow for even longer delays). The delay gives your IDE devices more time to spin up before the BIOS initializes them.

If you do not use old IDE drives and the BIOS has no problem initializing your IDE devices, it is recommended that you leave the delay at the default value of 0 for the shortest possible boot time. IDE devices manufactured in the last few years will have no problem spinning up in time for initialization. Only older IDE devices may have slower spin-up times.

However, if one or more of your IDE devices fail to initialize during the boot up process, start with a delay of 1 second. If that doesn’t help, gradually increase the delay until all your IDE devices initialize properly during the boot up process.

 

Details

Regardless of its shortcomings, the IDE standard is remarkably backward compatible. Every upgrade of the standard was designed to be fully compatible with older IDE devices, so you can actually use the old 40 MB hard disk drive that came with your ancient 386 system in your spanking new Intel Core i7 system! However, even backward compatibility cannot account for the slower motors used in the older drives.

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 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.

512 KB Read 239.84 MB/s 371.76 MB/s – 35.5%
512 KB Write 257.09 MB/s 488.15 MB/s – 47.3%
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 0.17 ms 0.15 ms – 11.8%
4 KB Write 0.08 ms 0.08 ms

The small random write access time of the 1TB WD Blue SSD was completely masked by the large SDRAM cache, allowing it to match the performance of the 240 GB HyperX Savage SSD. The small random read access time was also very good, coming within 12% of the HyperX Savage. However, due to the lack of NAND channels, its large access times were almost twice as long.

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.

 

Multiple I/O Comparison

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.

[adrotate banner=”4″]

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!

ADATA SC660H and SV620H External SSDs Updated

Taipei, 8 December 2016ADATA Technology today launched the updated SC660H and SV620H external SSDs.

Based on previous designs, the new models are part of the ADATA move to 3D NAND Flash in all new SSDs and in refreshes of existing models. The SC660H and SV620H feature 3D TLC NAND instead of traditional 2D NAND to provide increased reliability, durability, and efficiency.

The drives connect to host PCs via USB 3.1 Gen 1, and are presented in two distinct enclosure styles. Thanks to 3D NAND, the updated SSDs are available in 256GB and 512GB as opposed to 240GB and 480GB in the original SC660/SV620. Performance is 440MB/s read and 430MB/s write in both models.

ADATA SC660H : ultra-thin and tough elegance

The SC660H measures just 9.6mm tall. Its slim enclosure uses electroplated and textured titanium, ensuring a high degree of resistance against shocks, scratches, paint chipping, and fingerprints. The SC660H weighs a mere 73g, a fraction of the bulk of an external mechanical hard drive.

 

ADATA SV620H : elevating external SSD design

Also light and slender, the SV620H likewise employs a sandblasted titanium enclosure that makes it shock and scratch resistant. Its flat surfaces are raised 0.75mm, so that even when moved across a desk or other area the risk of unsightly scratches is minimized. The SV620H weighs 76g, and like its SC660H sibling has a cool blue activity LED.

 

[adrotate banner=”4″]

Bigger capacity in the same space plus added reliability

The 3D TLC NAND used on the two external SSDs is more reliable than 2D NAND and enables “packing” more storage into identical product chassis. At 256GB and 512GB, the SC660H and SV620H offer more space than their predecessors without consuming extra power. They are extremely efficient and ideal for notebook PCs thanks to placing very little stress on batteries.

Like all SSDs, they run totally silent and cool. With their 3D NAND, the SC660H and SV620H simply offer a better value than 2D NAND-based external SSDs, representing another step in ADATA embracing new technology to benefit consumers worldwide.

Transcend SSD230 SSD With 3D NAND Flash Revealed

1 November 2016Transcend Information, Inc. is proud to announce the launch of a brand new SSD with built-in 3D NAND flash. With the growing needs for high-capacity and high-performance storage, Transcend has adopted 3D NAND flash technology for the 2.5” Transcend SSD230 solid state drives, boosting storage capacity, transfer rates, and reliability all at once.

3D NAND Flash Technology for Upgraded Capacity, Performance, and Endurance

To achieve higher densities, 2D planar NAND flash technology shrinks each memory cell onto a single layer of cells. However, this technology increases cell-to-cell interference and hence reduces reliability as it approaches its physical scaling limit. 3D NAND flash was developed to resolve this bottleneck, as it features multiple layers of memory cells stacked vertically.

3D NAND flash not only resolves the density limitations of 2D horizontal NAND, but also boosts read and write performance, as it does not require the invocation of algorithms to prevent data corruption. Free from cell-to-cell interference, state-of-the art 3D NAND flash technology also features higher endurance and lower power consumption.

Exceptional Performance up to 560MB/s and Enhanced Reliability

[adrotate banner=”4″]

Besides built-in 3D NAND flash, Transcend’s SSD230 is equipped with a DDR3 SDRAM cache that provides an incredible 4K random read and write performance of up to 340MB/s, making it the perfect choice as a boot disk for everyday computing tasks and programs.

Taking full advantage of the SATA III 6Gb/s interface and built-in SLC caching technology, the SSD230 achieves exceptional sequential transfer speeds of up to 560MB/s read and 520MB/s write. In addition to blazing-fast transfer speeds, the SSD230 also features a RAID engine and LDPC (Low-Density Parity Check) coding, a powerful ECC algorithm, to keep data secure.

Exclusive SSD Scope Software

Developed for download and use with Transcend’s SSD products, SSD Scope is advanced, user-friendly software that makes it easier to maintain a healthy and efficient SSD. This software brings together the latest technology to determine the condition and optimize the performance of an SSD.

Plextor S1 Series MLC SSD Launched

The trend of SSD nowadays is shifting from MLC to a more cost efficient TLC flash memory and Plextor too with no exception, will be fully adopting the TLC memory on its upcoming products. As there are users who still prefer MLC SSD, Plextor today announced its last model in the MLC SSD product line, the Plextor S1 Series SSD for these users.

 

Plextor S1 Series

Plextor S1 Series are designed with the best price-performance ratio in mind to meet the need of the South east Asian Market and will only be available for the Southeast Asia region because of the limit edquantity of the MLC SSD. This means,you will have to come to the South east Asia region for the last chance to buy the MLC flash memory based SSD.

The strength of S1’s core components comes from the Toshiba’s high-quality Toggle Mode MLC NAND flash memory, as well as the SMI’s well-reputed SM 2246 controller. By extending Plextor’s exclusive firmware technology, and employing industry-preferred components, the S1 series provides users with performance up to 510/440MB/s in sequential read/write and 74K/79K IOPS in random read/write, respectively.

ADATA XPG SX8000 Gaming SSD Launched

Taipei, 29 September 2016 – ADATA Technology, a leading manufacturer of high performance DRAM modules and NAND Flash products, today launched the XPG SX8000 SSD, which uses an M.2 form factor loaded with 3D MLC NAND Flash and an SMI 2260controller.

The SX8000 meets NVMe 1.2 specifications and connects directly to motherboards via PCI Express 3.0 x4 (PCIe 3×4) to deliver 2.4GB/s read and 1GB/s write, with 100K/140K IOPS. The SX8000 arrives in diverse capacities (128GB, 256GB, 512GB, and 1TB), ensuring a new generation of SSD performance is available to more users.

A slightly faster version fitted with an attractive XPG heatsink will release by the end of October, promising an aesthetic bonus for case modding enthusiasts.

 

ADATA XPG SX8000

Compact M.2 PCI 3×4 shatters speed barriers

The XPG SX8000 connects to desktop and notebook PCs via low profile M.2 2280 and channels data through PCI Express 3.0 x4 (four lane). The low latency and big bandwidth of PCIe enable up to 2.4GB/s read and 1GB/s write – four times the read and twice the write performance of average SATA 6Gb/s SSDs. Random 4K IOPS figures are 100K read and 140K write, also significantly more than SATA-based drives.

The SX8000 features full NVMe 1.2 compatibility, powering a large performance boost that means users notice gains in real world scenarios, especially loading times within games that require heavy asset streaming and in professional applications such as graphics and audio rendering.

Flexible and durable 3D NAND

The XPG SX8000 represents a new era not just in performance, but in its very architecture. It uses reliable 3D MLC NAND Flash, allowing ADATA to produce versions in capacities from 128GB to 1TB. With 3D NAND, reliability, performance, and efficiency all get a boost as more storage is fitted onto a smaller form factor without increasing power demands. The SX8000 features a 2 million hour MTBF (mean time between failures) rating, or 25% longer than 2D NAND SSD (which average 1.5 million hours).

Range of data-enhancing features

ADATA firmware design takes utmost data performance and integrity into consideration with every SSD. Intelligent SLC Caching allows the drive to operate in pseudo single-level cell mode for speed boosts when extreme data loads are encountered. It can also leverage system RAM to increase performance via DRAM Cache Buffer, helping maintain consistent throughput even during the most intense tasks.

LDPC ECC (low density parity check error correction) prevents data corruption and promotes integrity, while Data Shaping evenly distributes task loads across NAND Flash cells. The SX8000 is therefore a pioneer in performance that offers a complete package of reliability-augmenting features. It is backed by a 5-year warranty.
