Hardware Setup
Our current test bed reflects changes in the marketplace over the past six months. Based upon the continuing proliferation of dual core processors and future roadmaps from AMD and Intel signifying the end of the single core processor on the desktop in the near future, we settled on an AMD Opteron 170. This change will also allow us to expand our real world multitasking benchmarks in the near future while providing a stable platform for the next six months. We are currently conducting preliminary benchmark testing under Vista with both 2GB and 4GB memory configurations. We will offer real-world Vista benchmarks once the driver situation matures but IPEAK results will continue to be XP based as the application is not compatible with Vista.
Test Setup - Software
With the variety of disk drive benchmarks available, we needed a means of comparing the true performance of the hard drives in real world applications. While we will continue to utilize HDTach and PCMark05 for comparative benchmarks our logical choice for application benchmarking is the Intel iPeak Storage Performance Toolkit version 3. We originally started using this storage benchmark application in our Q2 2004 Desktop Hard Drive Comparison. The iPeak test can be designed to measure "pure" hard disk performance, and in this case we kept the host adapter consistent while varying the hard drive models. The idea is to measure the performance of individual hard drives with a consistent host adapter.
We utilize the iPeak WinTrace32 program to record precise I/O operations when running real world benchmarks. We then utilize the iPeak AnalyzeTrace program to review the disk trace file for integrity and ensure our trace files have properly captured the activities we required. Intel's RankDisk utility is used to play back the workload of all I/O operations that took place during the recording. RankDisk generates results in a mean service time in milliseconds format; in other words, it gives the average time that each drive took to fulfill each I/O operation. In order to make the data more understandable, we report the scores as an average number of I/O operations per second so that higher scores translate into better performance in all of our iPeak results. While these measurements will provide a score representing "pure" hard drive performance, the actual impact on the real world applications can and will be different.
Each drive is formatted before each test run and three tests are completed in order to ensure consistency in the benchmark results. The high and low scores are removed with the remaining median score representing our reported result. We utilize the NVIDIA nF4 SATA ports along with the NVIDIA IDE-SW driver to ensure consistency in our playback results when utilizing NCQ, TCQ, or RAID settings. Although we test NCQ capabilities, all of our reported results are generated with NCQ off unless otherwise noted. We will test our Deskstar 7K1000 with AAM and NCQ turned on as AAM does not noticeably impact performance and this drive performs better with NCQ on in the majority of our tests.
Our iPeak tests represent a fairly extensive cross section of applications and usage patterns for both the general and enthusiast user. We will continually tailor these benchmarks with an eye towards the drive's intended usage and feature set when compared to similar drives. In essence, although we will reports results from our test suite for all drives, it is important to realize a drive designed for PVR duty will generate significantly different scores in our gaming benchmarks than a drive designed with gaming in mind such as the WD Raptor. This does not necessarily make the PVR drive a bad choice for those who capture and manipulate video while also gaming. Hopefully our comments in the results sections will offer proper guidance for making a purchasing decision in these situations. Our iPeak Test Suite consists of the following benchmarks.
VeriTest Business Winstone 2004: trace file of the entire test suite that includes applications such as Microsoft Office XP, WinZip 8.1, and Norton Antivirus 2003.
VeriTest Multimedia Content Creation 2004: trace file of the entire test suite that includes applications such as Adobe Photoshop 7.01, Macromedia Director MX 9.0, Microsoft Windows Media Encoder 9.0, Newtek Lightwave 3D 7.5b, and others.
AVG Antivirus 7.1.392: trace file of a complete antivirus scan on our test bed hard drive.
Microsoft Disk Defragmenter: trace file of the complete defragmentation process after the operating system and all applications were installed on our test bed hard drive.
WinRAR 3.51: trace file of creating a single compressed file consisting of 444 files in 10 different folders totaling 602MB. The test is split into the time it takes to compress the files and the time it takes to decompress the files.
File Transfer: individual trace files of transferring the Office Space DVD files to our source drive and transferring the files back to our test drive. The content being transferred consists of 29 files with a content size of 7.55GB.
AnyDVD 5.9.6: trace file of the time it takes to "rip" the Office Space DVD. We first copy the entire DVD over to our source drives, defragment the drive, and then measure the time it takes for AnyDVD to "rip" the contents to our test drive. While this is not ideal, it does remove the optical drive as a potential bottleneck during the extraction process and allows us to track the write performance of the drive.
Nero Recode 2: trace file of the time it takes to shrink the entire Office Space DVD that was extracted in the AnyDVD process into a single 4.5GB DVD image.
Game Installation: individual trace files of the time it takes to install Sims 2 and Battlefield 2. We copy each DVD to our secondary test drives, defragment the drive, and then install each game to our source drive.
Game Play: individual trace files that capture the startup and about 15 minutes of game play in each game. The Sims 2 trace file consists of the time it takes to select a pre-configured character, setup a university, downtown, business from each expansion pack (pre-loaded), and then visit each section before returning home. Our final trace file utilizes Battlefield 2 and we play the Daqing Oilfield map in both single and multiplayer mode.

I think you are right, but don't forget that in this post you are only looking at it from a performance viewpoint. Drive longevity and acoustics are major factors to me, and I think for you too from the article. I think these are the metrics worth looking at and tend to agree that subjective performance doesn't really differentiate that much (although I haven't had half as much experience with different vendors/models as you have).gramboh - Monday, March 19, 2007 - link
I read the review earlier this morning but don't recall seeing anything about retail channel availability. Did Hitachi or Dell comment to AT about this?I'm actually interested in 500GB 7200.10's and hoping this release will push the price of those down a lot.
Gary Key - Monday, March 19, 2007 - link
We do not have an exact date. Hitachi committed to having product into the retail channel by the end of Q1. We should have an answer from Dell tomorrow on when they will offer it outside of their systems. Hitachi is saying the drive will launch at $399, just waiting to see $550 price tags when the first drives show up... ;)Jeff7181 - Monday, March 19, 2007 - link
This might find it's way into my computer later this year. :)BUL - Monday, March 19, 2007 - link
Interesting that perpendicular technology was chosen given the R&D costs (with the tiny return of ~5 years before obsolescence--the article mentions that perpendicular can ONLY go 5x denser with existing techology & figure we'll see 5TB perpendicular drives in 2 years), etc... So why don't manufacturers offer 5 1/4" drives? Not to invoke memories of the MFM drives of long-ago (the original XT had a double-size 5 1/4" MFM drive of 10MB), but they have potentially 50-60% more surface area per platter, and with a possibility of 7(?) platters, isn't that a better solution? True, you wouldn't put them in SFFs or notebooks, but how many of us have towers with empty 5 1/4" bays??? And I assume that a 1TB 5 1/4" drive would be more energy-efficient than two 500GB 3 1/2" drives...Also, has anyone REALLY tested to see if perpendicular is truly a reliable technology? Seems like manufacturers have 50 years of experience with parallel storage, and only 1-2 years using perpendicular storage...

Bulkier, slower, less energy efficient and more moving parts that reduce reliability all in the name of increased capacity is not the way to the future. I think the biggest problem at the moment is NOT storage capacity, they're mostly increasing capacity to keep HDs evolving and not drop in price, as it's one of the only competitive advantages. If you can increase capacity with the same material cost and some extra R&D, it would be stupid not to do it, and a better way than increasing the material cost.In fact, regular folk have way too much capacity at the moment. A Seagate CEO worded it nicely a while back "Face it, we're not changing the world. All we do is enable people to store more crap/porn."
The future lies in the direction of flash based hard drives: smaller, less/no moving parts instead of more, faster access times, lower energy consumption/heat. Or other alternative technologies that offer the same advantages. The densities and cost are the only reasons we're not all buying them at the moment, something that should be fixed over time.
If you're worried about unused case slots, buy one of those things that enable you to install normal hard drives in it, or convince the case designers to include more 3 1/2" slots and less 5 1/4" slots.

Have you ever seen a slow motion filming of a cd-rom disk wobbling? Same thing here! I think the platters got smaller because the vibrations produced by them grew with the speed. Since today's r/w heads need to be extremely close to the surface, that would be utterly impossible to control at that speed and diameter. They changed also from an aluminum based disk to an glass based one also, because the roughness of the surface on the Al platter.tygrus - Monday, March 19, 2007 - link
It's harder to spin a large diametter platter at high speed. More weight, more wobble, slower access times. I saw once a 5.25" 4x2.5" SATA drive array. Quantum used to do a large format BigFoot for cheap, slow large capacity but it wasn't continued. We have plenty of capacity per platter but limited perf/GB (worse every year) so why decrease performance to increase capacity ?piroroadkill - Monday, March 19, 2007 - link
All of the Seagate Barracuda 7200.10 drives have been perpendicular for some time..It seems like a perfectly reliable tech to me

How smart is it to use temperatures from SMART?Did you verify all HDDs use good quality unbiased temperature sensors?
> Our thermal tests utilize sensor readings via the S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) capability of the drives and are reported by utilizing the Active SMART 2.42 utility.
