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've been curious how much help drives would get from a larger cache. What if smaller drives came with, say, 64MB of cache?JarredWalton - Monday, March 19, 2007 - link
Looking at the 750GB Seagate with its 16MB cache, there are definitely areas where the 32MB cache helps. Basically, with the larger capacities you need more cache to effectively handle all the data. Realistically, I'd say there's about 0% chance we'll see 64MB cache on smaller drives. When we're running 2TB drives, however....atomicacid55 - Monday, March 19, 2007 - link
I wish that the T7K500 could be reviewed in this. After all, that's the current challenger to the 7200.10, and if you read STR, the consensus is that it's an overall faster drive than the 7200.10. Every drive manufacturer tends to set its own trends in performance, and I personally believe it's more useful to have a comparison of the 7K1000 with its sibling rather than only against other brands.Gary Key - Monday, March 19, 2007 - link
Hitachi is finally sending us a T7K500. We will have a 500GB roundup with the latest drives from WD, Seagate, Samsung, and Hitachi in April.dm0r - Monday, March 19, 2007 - link
Never thought a 7200 RPM drive could be very competitive to a 10000 one...Thanks to its 32 Mb Cache.Loved the acoustics test, it shows a very quiet drive.With this new drives coming to the market, Western Digital will have to think about its raptors Overpriced drives and low its prices.Very good review.A question: How many Hitachi drives will be lauched with Perpendicular recording like this and what capacities?
Justin Case - Wednesday, March 21, 2007 - link
Higher areal density means more data can be read per rotation, so it could even be faster in terms of STR. But 7200 RPM drives will still have higher latency than 10k models, of course. The only way to overcome that would be to add more heads (ex., 2 per platter).bkiserx7 - Monday, March 19, 2007 - link
...wonder what a perpindicular raptor will do one day?crimson117 - Monday, March 19, 2007 - link
Attack prey from right angles?cruzer - Monday, March 19, 2007 - link
On page 10, "As stated in the article, we believe leaving AAM and NCQ turned provides the best experience with this drive."Do you mean turned on or off?

I really want 3 of them for raid 5 setup :)
