Review of First 10K IDE Drive 322
Sivar writes "StorageReview has a review of the first 10,000 RPM IDE hard drive. Despite the speed that other technologies are improving, this is the first rotational speed increase in almost six years for standard IDE drives." The review is pretty thorough, but also warns to keep in mind that the reviewed unit is only beta hardware.

The move from ISA to PCI as the general PC slot was a very good step forward. Gone were the hair-pulling configuration issues, jumper settings, and "ISA Plug'n'Play" that sometimes worked.
The next "PCI" for the PC will most likely be something like 3GIO, which was recently renamed to "PCI Express." It's a new bus, but it's software-compatible with PCI. Since PCI Express is a new hardware interface (new slots) it's not just for compatibility; it's because PCI works and there's no reason to change what you don't need to change.
At any rate, this topic is IDE drives. 10K SCSI drives tend to be pretty loud and run quite hot. I think that the 10k IDE drives will probably imploy some sort of technologies to keep them quiet and cooler, since IDE drives generally live on the desktop.

The reviewed drive has a 5 year warranty. How long is the warranty on your slower drive?
The Seagate Cheetah X15.3 is the world's fastest hard drive (until the Maxtor Atlas 15K is released). It is one of the most reliable drives you can buy, with an extremely high rating in StorageReview.com's reliability survey, and an excellent history in IBM, Dell, etc's enterprise servers.

The platter has to be so flat that, spinning at thousands of RPM, the heads must float above the platter at less than 1/50 the width of a human hair, or slightly more distance than the width of an average smoke particle.

As far as reliability, the WD Raptor is targeted at servers and has a 5-yr warranty. Western Digital has experience designing SCSI drives, and I suspect that the Raptor is essentially a 10,000RPM SCSI assembly with a serial ATA--instead of SCSI--interface (as well as a few other tweaks). Certainly the mechanical characteristics appear to strongly resemble common 10,000RPM SCSI drives, such as the sub-6 millisecond access times.

The Raptor has a 5-yr warranty (5 times as long as most desktop hard drives) and is targetted for the server market. Unless WD seriously screwed up, I am willing to be that it is about as reliable as other enterprise 10K drives (all of which are SCSI)--that is to say, incredibly reliable.
A 10k IDE drive is bound to have a ton of hard drive space
Actually, the faster the platter spins, the lower density each platter must be in order for the heads to keep up. For example, the Western Digital Raptor is a 36GB drive with a single 36GB platter (that's 18GB/side). This is the same size of platter as on the largest of 10KRPM SCSI drives.
To contrast, the largest platter size on a 7200RPM drive is 80GB/platter (or 40GB/side), and Weste3rn Digital is about to release a 250GB drive which will have three 83.3GB platters.
Higher platter density improves speed as well, but generally speaking (VERY generally speaking), increasing rotational speed improves drive performance more than having a somewhat higher density platter. Those of course varies based on what you are doing with the drive, whether it involves lots of random accesses (mail/webserver) or lots of linear accesses (video editing) or something in between.
In general, expect higher RPM drives to trail behind lower RPM drives in platter density, and therefore in maximum available disk space.

It happens that many operating systems use hard disk space as a substitute for RAM when there isn't enough physical memory, but the use of hard drive space as memory is not the definition of virtual memory.

Compare the price of 4GB of RAM with a 10GB hard drive. Also note that all memory used for a RAMdisk (as disk which will vanish once power is turned off) will be unavailable to applications.
Notice that computers run on multiple tiers of increasingly large and decreasingly expensive storage. This has been found to have the best performance/cost ratio. First we have registers, then L1 cache (except for Pentium IV's), then L2 cache, then on some systems L3 cache, THEN RAM, then the hard drive.
RAM is simply not cost effective for mass storage, and the performance benefits of using a RAMdrive really aren't very noticeable for many tasks. They help immensely for extremely random I/O, like running a mailserver, but Office and Diablo2 aren't going to run so much faster that it justifies the huge jump in cost and huge increase in risk (RAM drive dying when power goes out).
Besides, if we used a slow hard drive to load 4GB of data into RAM, can you imagine how long booting the system would take?
That said, there are companies offering battery-backed RAMdrives which fit in a PCI slot, and there are those (Armadillo comes to mind) which offers huge, fast FLASH-RAM drives in both IDE and SCSI flavors, but they are very expensive. There's more to making one than simply collecting a bunch of DIMMS together, ya know.
Re:I know it's a joke, but (Score:3, Redundant)
The point is - hard drives with high transfer rate (okay, so 10k will afford you a few microseconds of access time too) have very few benefits, and only in a very few areas (that *I* can think of, anyway):
1) video-edit
2) system boot
3) kernel compile; maybe
4) swap
now, with a large enough memory, you shouldn't ever NEED to swap, or worry about using massive space for kernel compile (and really now, you gentoo kids need to chill out a little), etc etc.
For video edit, you can use the extra space anyhow so for similar price a RAID 7.2k drive array would work out better price/perf wise, I'd think (and sorry but a raided 7.2k would get better rates than 10k single, while probably not costing much more). (with raid card, you can get probably three 7200 drives while only two 10k drives)
so, besides boot-time, WHY would you need a faster hard-drive; or the question being, why invest the money into a faster drive, instead of a LOT of memory?
can you imagine how your system will scream if it never have to page, ever again? (technically, you can't really "page" anyhow since you already filled all 32 bits - that's AFAIK, correct me if you know better; it's been a while)
so, it's more like a economics question.
I am not really suggesting RAMDISK, btw - I just think that you can compile your OS / programs with option like "I have massive memory so use it lavishly and don't touch that drive."

That said, when I told FreeBSD to "build world" using a RAMdisk as its temp directory, the build sped up by roughly 30%. It's difficult to tell exactly how much it sped up, since the CVS I compiled between the two methods was two days different, but it's a good ballpark figure.
In any case, you can completely disable paging to disk in both Windows and Linux. It can make a rather large difference in Windows, since it loves to swap out programs regardless of how much RAM you have, but in Linux it makes little difference. With 512MB RAM, I have only seen Gentoo use swap once, and that was for under 100K of data. (why it bothered, I do not know.)
So, that's already taken care of in Linux more or less.
As far as "Why invest in a faster hard drive rather than more memory", having more memory won't improve the speed as which programs load the first time, won't improve the speed at which you can copy files, won't increase the number of simultaneous video or audio streams your system can handle, etc. It's really a matter of what you want to improve the performance you want to improve the performance of. After you hit a certain "sweet spot" in RAM (currently I'd say 512MB), adding more doesn't really do that much for you, but adding a much faster hard drive can noticeably improve system responsiveness further. An easy/expensive test for this which I have done is to run a system with a slow hard drive and with a fast one. In my case, I tried with an ancient 3GB Western Digital Caviar and with a Maxtor Atlas 10K-3, then the fastest 10,000RPM drive.
Biiiiig difference.

Perhaps a little googling would have enlightened you as to what exactly an MTBF is. It's not quite as simple as it sounds:
(Thus spoketh the web page:)
It is generally accepted among reliability specialists (and you, therefore, must not question it) that a thing's failure rate isn't constant, but generally goes through three phases over a thing's lifetime. In the first phase the failure rate is relatively high, but decreases over time -- this is called the "infant mortality" phase (sensitive guys these reliability specialists). In the second phase the failure rate is low and essentially constant -- this is (imaginatively) called the "constant failure rate" phase. In the third phase the failure rate begins increasing again, often quite rapidly, -- this is called the "wearout" phase. The reliability specialists noticed that when plotted as a function of time the failure rate resembled a familiar bathroom appliance -- but they called it a "bathtub" curve anyway. The units of failure rate are failures per unit of "thing-time"; e.g. failures per machine-hour or failures per system-year.
What, you may ask, does all this have to do with MTBF? MTBF is the inverse of the failure rate in the constant failure rate phase. Nothing more and nothing less. The units of MTBF are (or, should be) units of "thing-time" pre failure; e.g. machine-hours per failure or system-years per failure but the "thing" part and the "per failure" part are almost always omitted to enhance the mystique and confusion and to make MTBF appear to have the units of "time" which it doesn't. We will bow to the convention of speaking of MTBF in hours or years -- but we all know what we really mean.
What does MTBF have to do with lifetime? Nothing at all! It is not at all unusual for things to have MTBF's which significantly exceed their lifetime as defined by wearout -- in fact, you know many such things. A "thirty-something" American (well within his constant failure rate phase) has a failure (death) rate of about 1.1 deaths per 1000 person-years and, therefore, has an MTBF of 900 years (of course its really 900 person-years per death). Even the best ones, however, wear out long before that.
This example points out one other important characteristic of MTBF -- it is an ensemble characteristic which applies to populations (i.e. "lots") of things; not a sample characteristic which applies to one specific thing. In the good old days when failure rates were relatively high (and, therefore, MTBF relatively low) this characteristic of MTBF was a curiosity which created lively (?) debate at conventions of reliability specialists (them) but otherwise didn't unduly bother right-thinking people (us). Things, however, have changed. For many systems of interest today the required failure rates are so low that the MTBF substantially exceeds the lifetime (obviously nature had this right a long time ago). In these cases MTBF's are not only "not necessarily" sample characteristics, but are "necessarily not" sample characteristics. In the terms of the reliability cognoscenti, failure processes are not ergodic (i.e. you can't blithely trade population statistics for time statistics). The key implication of this essential characteristic of MTBF is that it can only be determined from populations and it should only be applied to populations.
MTBF is, therefore an excellent characteristic for determining how many spare hard drives are needed to support 1000 PC's, but a poor characteristic for guiding you on when you should change your hard drive to avoid a crash.

First.. interface technologies:
SCSI and IDE are different. IDE has controller hardware on the drive, and the IDE interface is nothing more than a mere i/o port. SCSI has a dedicated controller, and the drives have less logic. In theory.
Also in theory, (and usually in practice), scsi is better at handling multiple drives.... the controller & scsi bus can take care of all kinds of multi drive operations without burdening the rest of the system. With IDE, obviously, as each drive is it's own controller, multi-drive operations require the cpu to do more stuff. This can be mitigated, of course, with IDE raid controllers and whatnot that use IDE drives but are in fact an actual controller... and take the load off the system.
IN practice, however, drives with SCSI interfaces are generally manufactured for business/server markets, and are built with better parts/better testing, and hence, don't fail as much. They are also built with faster components and whatnot, again because they are in the server market.
So.. these arguments always turn into flamewars. The fact is, scsi can do more, and scsi drives tend to be more reliable.... (which has to do with market pressure and NOT the scsi interface)
There is no real big reason, however, why and IDE raid card & drives cannot provide the same quality of service.

Introduction
StorageReview.com readers have been speculating for the better part of three years on when the industry would ratchet up the spindle speed of ATA hard drives. When would it happen? Which company would start the trend? Speculation finally gave way to a real announcement on February 10th when Western Digital officially announced its Raptor Serial ATA drive.
Western Digital is in many ways the perfect company to lead ATA to a next-generation spindle speed. Ever since it introduced the Caviar WD400BB, WD has consistently led the field when it came to ATA performance. That's a 2.5-year run at the top- very impressive in the competitive computer hardware field. More importantly, however, the firm has no SCSI business to protect. The last thing that established SCSI powerhouses such as Seagate, IBM, and Maxtor want to see is the erosion of the relatively cushy margins associated with SCSI drives. Now that WD has opened this veritable Pandora's Box, the competition is sure to follow.
According to WD, the key factor holding back higher spindle speeds was parallel ATA's lack of specification-level hot swap functionality. To be successful (initially, at least), any 10k RPM ATA drive must gun for the enterprise market. And in the enterprise, a sector that views outages as unacceptable, the ability to swap out a failed drive for another unit with minimal downtime is crucial. Serial ATA provides for such hot-swap functionality. Now that SATA is trickling into the channel, WD believes 10k RPM ATA's time has come.
The Raptor comes in just a single configuration- a single 36-gigabyte platter. WD specifies the drive's seek time at just 5.2 milliseconds, solidly within SCSI territory. An 8-megabyte buffer accompanies the drive. Some folks may be disappointed with the drive's relatively paltry capacity- after all, today's SCSI drives deliver 147 GB of storage in a low-profile chassis. Much like its namesake made popular by 1993's Jurassic Park, however, WD envisions Raptors in multiple-drive configurations running off of relatively inexpensive SATA RAID controllers. Reflecting its enterprise orientation, the Raptor claims a 1.2 million hour MTBF spec and features a five-year warranty.
It is important to note that the market for the Raptor is primarily the entry- and mid-level server markets and not the enthusiast desktop sector. When Western Digital raised the bar nearly 1.5 years ago, we repeatedly pointed out that the Special Edition (JB series) Caviar was what readers really wanted when they speculated over 10,000 RPM ATA drives. Equipped with an 8-megabyte buffer and accompanying firmware aggressively tuned for single-user scenarios, the WD1000JB easily matched and even exceeded the performance that the best 10k RPM SCSI drives of the era delivered when it came to desktop performance. While SCSI drives feature superior mechanics, their server orientation forces them to trade away firmware optimized for highly-localized patterns in favor of strategies that maximize returns in random access scenarios. In the Raptor, WD faces much of the same quandary. With its enterprise-class warranty and seek time, however, its clear that server performance is WD's first priority for the Raptor.
The drive tested for this review is a beta unit provided by longtime SR sponsor HyperMicro.com rather than Western Digital itself. With a handful of exceptions, SR generally has not published performance figures for products this early in the development cycle. Please remember the final Raptor product may deliver results substantially different from those that follow.
Keeping that in mind, let's see what kind of performance this beta sample delivers!

WD360GD (BETA) Average Read Service Time
The beta Raptor delivers a measured average access time of 8.7 milliseconds. Subtracting 3.0 ms to account for the rotational latency of a 10k RPM spindle speed yields a measured seek time of 5.7 ms. While excellent for an ATA drive, the score is a bit off of the manufacturer's 5.2 ms claim as well as a bit higher than what we've come to expect from 10k SCSI drives.
The use of an external controller (the Promise SATA150 TX4) and its associated driver unfortunately makes it more difficult to consistently disable write caching which unfortunately precludes us from presenting average write access times.
eTesting Lab's WinBench 99 v2.0 features a test that measures a drive's read sequential transfer rates across the entire drive. The benchmark reports results both in quantitative numbers as well as in a graphic that plots the transfer rate across the capacity of the drive.

WD360GD (BETA) Transfer Rate
Despite its higher spindle speed, the Raptor's outer-zone transfer rates aren't much better than today's top 7200 RPM units. Its score of 57.6 MB/sec narrowly beats the Caviar WD2000JB and slightly trails the DiamondMax Plus 9. Thanks to its smaller platter diameter, the Raptor exhibits a bit less decay as it moves towards its inner zones. Its minimum score of 37.6 MB/sec tops other ATA drives yet still fails to reach the levels of a Cheetah or Atlas.

The beta Raptor turns in a StorageReview.com Office DriveMark 2002 of 418 I/Os per second. While such a score places it among the top ATA drives, the Raptor fails to match WD's own Caviar WD2000JB. A top-level 10k SCSI unit such as Maxtor's Atlas 10k IV substantially outpaces the Raptor.
Differences become more glaring in the High-End DriveMark. At just 300 I/Os per second, the Raptor places in the middle of a pack of 7200 RPM drives equipped with 2-megabyte buffers. Here the WD2000JB outscores the WD360GD by a substantial 43% margin.
The Windows XP bootup process recorded in the SR Bootup DriveMark 2002 features an unusually high average queue depth for a desktop scenario. In this test, the Raptor stretches its legs, easily besting all comparable ATA and SCSI disks.
Finally, in the SR Gaming DriveMark 2002, the Raptor delivers 531 I/Os per second, a figure comparable to a top-end ATA drive yet trailing the Atlas 10k IV by a significant margin.
To be fair, we should point out that the 36-gigabyte Raptor faces flagship drives of much greater capacity in our tests. The margins between the Raptor and smaller ATA or SCSI drives would likely not be as pronounced since the competition would then be forced to work across a greater percentage of its platter zones.

In the SCSI-stronghold of random, server-oriented performance, the Raptor, while delivering scores significantly better than traditional ATA drives, nonetheless falls behind contemporary SCSI drives by a significant margin. Even older drives such as the Seagate Cheetah 36ES (not represented; see the performance database to create custom comparisons) unquestionably trounce the WD360GD. The beta Raptor delivers the server performance that one would expect from a good 7200 RPM SCSI drive- definitely a cut above standard ATA, but not up to 10k RPM levels.

Objectively speaking, the beta Raptor turns in impressively low noise floors, likely due to its single-platter design. A score of 40.4 approaches the noise floor delivered by the latest Barracuda ATA drives. Subjectively speaking, however, our sample emits an irritating high-pitched squeal reminiscent of early 10k RPM SCSI disks. The whine was audible even over the testbed's relatively loud drive cooler fans.
Seek noises land somewhere between today's louder ATA disks and a typical reviewed SCSI unit. While the Raptor features random seeks similar to that of 10k RPM SCSI, it features just a single platter contrasted with the four typically found in today's flagship units. The resultant actuator noise is quite unobtrusive.
The Raptor's single-platter configuration also yields a relatively low operating drive temperature. Our measurements reached 20.6 degrees Celsius above ambient room temperature- on the high side for an ATA drive but well below the typical SCSI disk.
Conclusion...
It's very difficult to draw firm conclusions on a drive that is obviously far from its final state. Firms manufacture pre-release units not for performance demonstrations but rather for system-integration purposes- resellers need to qualify the unit in their systems for extended periods of time before the drive hits general availability.
Many readers may be disappointed with the Raptor's relatively lackluster desktop performance. For various reasons, enthusiasts view an increased spindle speed as the largest factor in single-user performance. The reality, however, is that desktop usage predominately consists of highly-localized patterns and is affected more by caching strategies than marginal mechanical improvements. Western Digital's JB series may very well continue to stand as the premiere choice for those seeking the ultimate in single-user speed.
We're more concerned with the Raptor's server performance. While it is definitely a step above standard 7200 RPM ATA drives, the beta Raptor trails today's 10k RPM SCSI drives by substantial margins. If WD and SATA are to have a chance at cracking the enterprise market, the Raptor's multi-user performance must approach the levels delivered by Cheetahs and Atlases.
Again, all figures, analyses, and conclusions have been drawn from an early pre-production sample. It is likely that the performance delivered by the final product will differ significantly from what we've seen today. We wish WD the best, and eagerly await the opportunity to officially put the Raptor through its paces.

Those said, I have a few other things I'd like to say. First of all, it's nice to see that the drive is quiet. Even many 5400 and 7200 RPM drives are quite loud today. It's nice to know that going to 10k isn't going to turn my PC into a jet engine. Also, they mention that the reason that we haven't seen 10k IDE drives before was that servers didn't want them since they couldn't be hotswapped like SCSI. SATA supports hotswap in theory, but can you hotswap today? I don't think Windows lets you, IIRC (or if it does the system is a bit unstable afterwards). Does Linux let you hotswap SATA drives? If all the drives are one one controller (say RAID 5, or something else redundant) and you swap a drive, does the OS even know it happened? I don't have any expirence with hotswapping hard drives.

I've heard this over and over, but I've never heard any justification for it. PCI is plenty fast for that disk, and it's hard to imagine that a new ns extra latency makes any difference in disk performance.
All the other drives in this review are either ATA or SCSI. So as SATA goes, this drive might be king of the hill by far.
Sure, it'll be king of the hill for about two months until Seagate and Maxtor come out with SATA versions of all their ATA drives.
Re:Things To Keep In Mind (Score:2)
Ok- here is the justification. Gen 1 SATA is theoretical 150 MB/sec to each drive (point to point). Most people have more than one hard drive, so multiply that 150 by the number of drives.
Standard 33 MHz 32 bit PCI is capable of around 133 MB/sec. One drive is enough to saturate that (in theory).
You might argue that current drives are not capable of sustaining the 150 MB/sec transfer rate, and that is correct. But then you realize that your NIC, modem, soundcard, and other devices are sharing that 133 MB/sec PCI bandwidth with your SATA controller, and that starts become a very limiting factor.
Re:Things To Keep In Mind (Score:2)
Integrated controllers have no real-world performance advantage over PCI-based other than that they do not use PCI bandwidth. PCI bandwidth is generally more than sufficient for a single (or double) drive. If integrated controllers do improve SATA performance, it will be because of tweaks in the controller design, not simply because they are integrated.
Drive Size - The drive in the review is up to 1/6th the size of some of the other drives in the review. So if you're comparing this drive you have to remember that it would perform better if it was a 160 gig drive and didn't have to work all over it's platter.SATA supports hotswap in theory, but can you hotswap today? I don't think Windows lets you, IIRCWindows 2000, at least server editions, let you hotswap SCSI drives. I imagine hotswapping SATA drives is more a matter of having the correct drivers than anything.
Linux supports hotswapping (of SCSI drives) as well, else it wouldn't be touched with aten foot pole in many server environments.
Even Windows 98 supports hotswapping to a degree. You can get an external USB or Firewire drive and hotswap them to your heart's content. Not quite the same, but not much different either.

According to WD's site, these drives have transfer rates comparable to the 8MB Cache IDE drives, but seek times in the 5 ms range (vs. around 8.5). Oh, and they're not particularly loud either, at least not anything I've noticed.
At $160, this drive doesn't seem like a good idea. I've seen numerous 10K ~36GB SCSI drives for about $30 more. I guess you can factor in the card cost if you honestly want to, but if you're talking about RAIDing these things, you're probably talking about buying a good SATA or IDE RAID card anyway.
If you have plans to archive every friggin' CD you own in FLAC format, then SCSI isn't a cost-effective method to go. I don't. YMMV, but I've found that I can beat the hell out of the computer and I don't see the nasty drive access issues that I used to.

This drive uses 36gb per platter.
On a 10,000 rpm drive the platters need to be somewhat smaller, due to them physically spinning faster it can cause "problems" with a full size 3.5" disk @ that speed.
Hence they physically make the disk smaller, so I can totally understand them NOT acheiving the current 7200rpm "flagship" 83gb per platter, however 36gb per platter is quite old for 10,000 rpm drives, which is quite a shame, 50 gb per platter would have been magnificent.
Unfortunately due to this, it indicates (at least to me) that this is nothing new technology wise, but a 10,000rpm disk with an SATA controller strapped on to it, they may have even licensed it from their buddies @ IBM (since they used to be chummy in the early 7200rpm days of ATA)
I'm having some guys on the SR forums claim the drive isn't that bad at all and that claiming it's a disapointment is silly because it still does X, and that's fine it's their opinion.
However MY opinion is that this drive LOGICALLY should be *THE* fastest ATA drive in existence, bar none in all benchmarks - that's what we enthusiasts want and what we will pay for - we want it to not only be faster than all 7200rpm drives (bar none) but be the fastest ATA drive period - if they can acheive this and truely blur that SCSI / ATA line - the "geeks / losers and enthusiasts" (read: myself and many others) will glady drop the same money we would normally drop to receive 2.5 and even 3x the space.
As I've said previously, most people (I feel) who initially saw the PR for this disk approx 3 weeks ago would have thought this: - "that drive will be the fastest at everything ever besides scsi" that's their expectations, and that's mine - and unfortunately it's not the case.
So some of you may like the drive, but after reading SR's review I'm not down with that drive at all - also take note the drive makes the distinct "10,000rpm whine" sound which is disapointing as well.
