Hard Disk Pre-Delay from The Tech ARP BIOS Guide!

Hard Disk Pre-Delay

Common Options : Disabled, 3 Seconds, 6 Seconds, 9 Seconds, 12 Seconds, 15 Seconds, 21 Seconds, 30 Seconds

 

Hard Disk Pre-Delay : A Quick Review

The Hard Disk Pre-Delay BIOS feature allows you to force the BIOS to delay the initialisation of your hard disk drives for up to 30 seconds. The delay allows 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 disable this BIOS feature for the shortest possible booting time. Most IDE devices will have no problem spinning up in time for initialisation.

But if one or more of your IDE devices fail to initialize during the boot up process, start with a delay of 3 Seconds. If that doesn’t help, gradually increase the delay until all your IDE devices initialize properly during the boot up process.

 

Hard Disk Pre-Delay : The Full 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 much newer Athlon XP system!

However, even backward compatibility cannot account for the slower motors used in the older IDE drives. Crucially, motherboards are capable of booting up much faster these days, initialising IDE devices 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 that IDE drive and the drive will not be accessible even though it is actually running just fine.

This is where the Hard Disk Pre-Delay BIOS feature comes in. It allows you to force the BIOS to delay the initialisation of your hard disk drives for up to 30 seconds. The delay allows 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 disable this BIOS feature for the shortest possible booting time. Most IDE devices will have no problem spinning up in time for initialization.

But if one or more of your IDE devices fail to initialize during the boot up process, start with a delay of 3 Seconds. If that doesn’t help, gradually increase the delay until all your IDE devices initialize properly during the boot up process.

Multi-Sector Transfers from The Tech ARP BIOS Guide

Multi-Sector Transfers

Common Options : Disabled, 2 Sectors, 4 Sectors, 8 Sectors, 16 Sectors, 32 Sectors, Maximum

 

Quick Review of Multi-Sector Transfers

The Multi-Sector Transfers BIOS feature speeds up hard disk drive access by transferring multiple sectors of data per interrupt instead of using the usual single-sector transfer mode. This mode of transferring data is known as block transfers.

There are a few available options, from Disabled and a few different multiple sectors option to Maximum.

The Disabled option forces your IDE controller to transfer only a single sector (512 bytes) per interrupt. Needless to say, this will significantly degrade performance.

The selection of 2 Sectors to 32 Sectors allows you to manually select the number of sectors that the IDE controller is allowed to transfer per interrupt.

The Maximum option allows your IDE controller to transfer as many sectors per interrupt as the hard disk is able to support.

Since all current hard disk drives support block transfers, there is usually no reason why IDE HDD Block Mode should be disabled.

Therefore, you should disable IDE HDD Block Mode only if you actually face the possibility of data corruption (with an unpatched version of Windows NT 4.0). Otherwise, it is highly recommended that you select the Maximum option for significantly better hard disk performance!

The manual selection of 2 to 32 sectors is useful if you notice data corruption with the Maximum option. It allows you to scale back the multi-sector transfer feature to correct the problem without losing too much performance.

The Maximum option allows your IDE controller to transfer as many sectors per interrupt as the hard disk is able to support.

Since all current hard disk drives support block transfers, there is usually no reason why IDE HDD Block Mode should be disabled.

However, if you are running on Windows NT 4.0, you might need to disable this BIOS feature because Windows NT 4.0 has a problem with block transfers. According to Chris Bope, Windows NT does not support IDE HDD Block Mode and enabling this feature can cause data to be corrupted.

Ryu Connor confirmed this by sending me a link to a Microsoft article (Enhanced IDE operation under Windows NT 4.0). According to this article, IDE HDD Block Mode and 32-bit Disk Access have been found to cause data corruption in some cases. Therefore, Microsoft recommends that Windows NT 4.0 users disable IDE HDD Block Mode.

Lord Mike asked ‘someone in the know‘ about this matter and he was told that the data corruption issue was taken very seriously at Microsoft and that it had been corrected through the Windows NT 4.0 Service Pack 2. Although he could not get an official statement from Microsoft, it is probably safe enough to enable IDE HDD Block Mode on a Windows NT 4.0 system, just as long as it has been upgraded with Service Pack 2.

Therefore, you should disable IDE HDD Block Mode only if you actually face the possibility of data corruption (with an unpatched version of Windows NT 4.0). Otherwise, it is highly recommended that you select the Maximum option for significantly better hard disk performance!

The manual selection of 2 to 32 sectors is useful if you notice data corruption with the Maximum option. It allows you to scale back the multi-sector transfer feature to correct the problem without losing too much performance.

Tech ARP 20th Anniversary Giveaway Week 7 – Western Digital!

Tech ARP is now 20 years old! To celebrate, we partnered up with many of the world’s TOP BRANDS to thank you all for your loyal support with a TWENTY-WEEK GIVEAWAY!   

 

Tech ARP Is 20 Years Old & Going Strong!

Time sure FLIES when you are having fun! Twenty years ago, Ken, Chai and I got together to rebrand Adrian’s Rojak Pot as Tech ARP. We were having trouble explaining what rojak was, and that pot did not refer to marijuana / cannabis! 

That was in the good old days of sawing off pipe end caps to turn into CPU water coolers, and modifying SLAB (sealed lead acid batteries) into the world’s first power bank for our PDAs (remember those?).

Those sure were CRAZY DAYS! 

Somehow, we worked our way to the forefront of motherboard technology with our seminal BIOS Optimization Guide, which later got published as Breaking Through The BIOS Barrier : The Definitive BIOS Optimization Guide for PCs.

I don’t know how I did it, but somehow, we did all those crazy stuff while I was still in medical school! CRAZY days indeed!

Over the years, we moved from strength to strength, with Ken hand-developing our own backend, and Chai nurturing our budding forums.

Somehow, we persevered and by the miracle of surviving the passage of time, Tech ARP is Malaysia’s oldest tech website!

Today, we are still pretty much the same team, with FalconeDashkenCarolyn, Hui Xin, Alyssa, Kar Hoe and Brian Chong helping us out here and there. Thank you, guys!

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!

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.

The 10TB WD Red (WD100EFAX) Hard Disk Drive Review

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. Today, we are going to look at the first helium-filled WD Red model – the 10TB WD Red (WD100EFAX) NAS drive!

 

The WD Red Family

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:

Warranty3 Years3 Years3 Years3 Years3 Years

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 10TB 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 10TB 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 10TB 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 10TB WD Red (WD100EFAX) 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 10TB WD Red (WD100EFAX) 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 10TB WD Red (WD100EFAX) 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.

Usable Capacity

The 10TB 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.

 

Platter Profile

The platter profile of the 10TB 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 10TB WD Red uses higher density platters, which gave it a very high throughput.

In fact, the outermost tracks of the 6TB WD Red only equalised the 10TB WD Red at the 6.5 TB point. Even at its slowest tracks, the 10TB WD Red was as fast as the 6TB 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 6TB WD Black, the 10TB WD Red drive was significantly cooler at full load. It ran a little warmer than the 8TB 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 10TB 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 10TB 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 6TB WD Black, that puts it ahead of most of its competitors.

Both the 8TB WD Gold and the 10TB WD Red have 7 platters. The 10TB WD Red use higher density 1.43 GB platters to compensate for the 8TB 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 10TB WD Red (WD100EFAX) NAS drive did very well in this benchmark, coming in faster than even the 6TB 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 (WD100EFAX) was far superior than the 6TB 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 (WD100EFAX) 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 10TB WD Red (WD100EFAX) would not make for a very good desktop drive.

This is the most important test for the NAS drives because it shows their ability to read and write files sequentially. The large sequential transfer performance is particularly important since many NAS system deal with large files (larger than 512 KB in this context).

Without a doubt, the 10TB WD Red (WD100EFAX) is much faster than the 6TB WD Red in all aspects. The biggest boost was in small sequential reads.

Our Verdict & Award

This is our second review of a helium-filled hard disk drive (after the 8TB 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 10TB 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 10TB 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 8TB 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 6TB 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!

32-bit Transfer Mode – The BIOS Optimization Guide

32-bit Transfer Mode

Common Options : On, Off

 

Quick Review

This BIOS feature allows you to command the IDE controller to combine two 16-bit hard disk reads into a single 32-bit data transfer to the processor. This greatly improves the performance of the IDE controller as well as the PCI bus.

Therefore, it is highly advisable to enable 32-bit Transfer Mode. If you disable it, data transfers from the IDE controller to the processor will only occur in 16-bits chunks.

 

Details

[adrotate banner=”4″]

This BIOS feature is similar to the 32-bit Disk Access BIOS feature. The name 32-bit Transfer Mode is actually a misnomer because it doesn’t really allow 32-bit transfers on the IDE bus.

The IDE interface is always 16-bits in width even when the IDE controller is on the 32-bit PCI bus. What this feature actually does is command the IDE controller to combine two 16-bit reads from the hard disk into a single 32-bit double word transfer to the processor. This allows the PCI bus to be more efficiently used as the number of transactions required for a particular amount of data is effectively halved!

However, according to a Microsoft article (Enhanced IDE operation under Windows NT 4.0), 32-bit disk access can cause data corruption under Windows NT in some cases. Therefore, Microsoft recommends that Windows NT 4.0 users disable 32-bit Disk Access.

Lord Mike asked ‘someone in the know’ about this matter and he was told that the data corruption issue was taken very seriously at Microsoft and that it had been corrected through the Windows NT 4.0 Service Pack 2. Although he couldn’t get an official statement from Microsoft, it’s probably safe enough to enable 32-bit Disk Access on a Windows NT 4.0 system, just as long as it has been upgraded with Service Pack 2.

Because it realizes the performance potential of the 32-bit IDE controller and improves the efficiency of the PCI bus, it is highly advisable to enable 32-bit Transfer Mode.

If you disable it, data transfers from the IDE controller to the processor will only occur in 16-bits chunks. This degrades the performance of the IDE controller as well as the PCI bus.

As such, you should disable this feature only if you actually face the possibility of data corruption (with an unpatched version of Windows NT 4.0).

You can also find more information on the Windows NT issue in the details of the IDE HDD Block Mode feature!

IDE HDD Block Mode – The BIOS Optimization Guide

IDE HDD Block Mode

Common Options : Enabled, Disabled

 

Quick Review

The IDE HDD Block Mode BIOS feature speeds up hard disk drive access by transferring multiple sectors of data per interrupt instead of using the usual single-sector transfer mode. This mode of transferring data is known as block transfers.

When you enable this feature, the BIOS will automatically detect if your hard disk drive supports block transfers and set the proper block transfer settings for it. Depending on the IDE controller, up to 64 KB of data can be transferred per interrupt when block transfers are enabled. Since all current hard disk drives support block transfers, there is usually no reason why IDE HDD Block Mode should be disabled.

Please note that if you disable IDE HDD Block Mode, only 512 bytes of data can transferred per interrupt. Needless to say, this will significantly degrade performance.

Therefore, you should disable IDE HDD Block Mode only if you actually face the possibility of data corruption (with an unpatched version of Windows NT 4.0). Otherwise, it is highly recommended that you enable this BIOS feature for significantly better hard disk drive performance!

[adrotate banner=”4″]

Ryu Connor confirmed this by sending me a link to a Microsoft article (Enhanced IDE operation under Windows NT 4.0). According to this article, IDE HDD Block Mode and 32-bit Disk Access have been found to cause data corruption in some cases.

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).

For more information, you can take a look at our in-depth review, or visit the official WD Gold product page.

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.

High Performance PCs Need High Performance Drives

In the early days of personal computing, hard disk drives were just a place to store our applications and files. Our requirements were simpler back then, and so were the hard disk drives. Over time, our personal computers became more powerful, and the way we use them changed.

We no longer just use them to run word processors and spreadsheets, but to edit photos, create and manipulate 3D models and even play games. This created the need for faster hard disk drives. Hard disk drive manufacturers responded by developing high-performance hard disk drives.

Many users make the common mistake of focusing too much on CPU and graphics card performance while ignoring the performance of their hard disk drives. Today, we are going to show you why high performance PCs need high performance drives.

 

Higher Spindle Speed

Traditionally, hard disk drives spin at 4,200 RPM. Today, most desktop hard disk drives spin at 5,400 RPM. High performance drives achieve better performance by spinning their platters at a higher speed – 7,200 RPM or even 10,000 RPM.

The higher spindle speeds not only deliver better transfer rates, but also greatly reduces seek times – how long it takes to move from one location on the drive platter to a different location.

Transfer Rate : The speed at which files are read from, or written to, the hard disk drive. Usually measured sequentially.

Seek Time : How fast the drive head can move from one location to another location on the platter. Usually measured randomly, the shorter the better.

A high transfer rate is useful when you are copying a lot of files off the drive, or writing a lot of files to it. It also helps to load applications and games faster.

However, the greatest advantage of high-performance drives is their low seek times. The operating system and any application or game you are running will feel faster because there is less delay in the data they request from the drive (which tend to be all over the platter).

 

Larger Cache

All hard disk drives have a SDRAM cache that keeps a copy the latest data or the most frequently-used data from the hard disk drive. If the data requested is in the SDRAM cache, then it is instantly accessed. If not, then it has to be read off the hard disk drive’s platter.

The larger the SDRAM cache, the more data can be stored in it, and the more likely the data you are requesting is in it. That’s why high performance drives have large SDRAM caches. While regular hard disk drives have 16 MB or 32 MB caches, a high performance drive come with 64 MB or 128 MB caches.

 

Faster Processor

All modern hard disk drives use a small (usually ARM-based) processor to handle all sorts of tasks – encoding data, performing error correction checks, Native Command Queuing (NCQ), power management, etc.

High-performance drives boast faster dual-core processors so they can perform these tasks faster. This ensures that the raw data being read from, or written to, the hard disk drive is never delayed even under the heaviest loads.

[adrotate banner=”5″]

 

Performance Advantage

To demonstrate the difference, here is a comparison of a 6 TB Western Digital Black hard disk drive against the 6 TB Western Digital Green hard disk drive. Both are hard disk drives from the same manufacturer – Western Digital. The difference is the Black drive is a high-performance drive, while the Green drive is an energy-efficient drive.

As you can see, the 6 TB WD Black drive is 32-60 MB/s faster than the 6 TB WD Green drive. That is a 36-42% boost in transfer rate. To put this into perspective, if you copy out 6 TB of data from each drive, it will take the WD Black drive just under 10 hours, but the WD Green drive will take almost 14 hours.

Now, let’s take a look at how fast they perform with small random reads and writes that happen when the drive is used by an operating system and applications.

The 6 TB WD Black drive is 62.5% faster in random writes, and 23% faster in random reads than the 6 TB WD Green drive. The WD Black drive’s significantly better small random write performance is due to the faster processor and larger cache.

 

WD Black High Performance Drives

The Western Digital Black family is a great example of high-performance drives for power users and gamers who want the fastest possible hard disk drive. We have been using them for years because they are not just fast, but very reliable. In fact, we have WD Black drives that are still running more than 8 years after we first spun them up!

Western Digital offers their Black drives in both 3.5″ desktop models, and 2.5″ laptop models. They offer the following advantages over regular hard disk drives :

  • Higher 7,200 RPM spindle speed, which gives higher transfer rates and faster random access times
  • A much larger cache : Up to 128 MB for desktop models, up to 32 MB for laptop models
  • Faster dual-core processors to better handle multiple, simultaneous accesses
  • A much longer 5 years warranty for greater peace of mind

For more information, you can read about the latest WD Black desktop hard disk drives that we tested here at Tech ARP :

And here are the WD Black mobile hard disk drives that we reviewed here at Tech ARP :

It is said that once you try a WD Black high-performance drive as a boot drive, you will never want to go back to a “regular” hard disk drive. They are available in all major IT malls, so you don’t have to worry about not being able to get your hands on one for your PC!

ARMD Emulation Type – BIOS Optimization Guide

ARMD Emulation Type

Common Options : Auto, Floppy, Hard Disk Drive

 

Quick Review

ARMD is actually short for ATAPI Removable Media Device. It refers to devices that use removable media. Examples include the LS-120, Magneto-Optical (MO) and Zip drives.

To boot up any operating system from these drives, it is essential for them to emulate a floppy drive or a hard disk drive. This is especially true for older operating systems like DOS.

This BIOS feature allows you to select the type of emulation used during the boot sequence.

When set to Auto, the BIOS automatically sets the emulation type used by ARMD drives.

When set to Floppy, ARMD drives will emulate a floppy drive at boot up.

When set to Hard Disk Drive, the ARMD will emulate a hard disk drive at boot up.

To be safe, this BIOS feature should be set to Floppy. It is the safest emulation type, and the one that most accurately describes ARMD drives. They are, after all, more like large-capacity floppy drives than hard disk drives.

Emulating the hard disk drive may provide better performance, if the operating system supports a disk cache. However, that may introduce data synchronization problems should you eject the media before the disk cache has a chance to write to the media.

[adrotate banner=”4″]

Emulating a floppy drive does not normally present with this problem. Only reads from floppy drives are normally cached, thereby avoiding this problem. In addition, certain operating systems (e.g. Windows XP) will only load drivers from a floppy drive during the installation process.

If you desire better performance, you should set this BIOS feature to Hard Disk Drive. However, you must treat the device like a hard disk drive and refrain from ejecting the media unless you are sure the cached data has been written to it.

To be safe, this BIOS feature should be set to Floppy. It is the safest emulation type, and the one that most accurately describes ARMD drives. They are, after all, more like large-capacity floppy drives than hard disk drives.
