Hard Disk Performance: PCMark 2005
We introduce PCMark 2005 into our hard disk benchmark suite. We utilize HDD test suite within the program. The program utilizes the RankDisk application within the Intel iPEAK SPT suite of tools to record a trace of disk activity during usage of real world applications. These traces can then be replayed to generate performance measurements based upon the actual disk operations within the application. The HDD test suite contains 53% read and 47% write operations with each trace section utilizing varied amounts of read or write operations. Additional information about the test suite can be found in PDF format here.
Our test results are based upon the following trace runs:
Windows XP Startup: This test consists of 90% reading and 10% writes that tracks XP activities at start-up.
Application Loading: This test consists of 83% reading and 17% writes that tracks the opening and closing of the following programs.
File Write: This test consists of 100% write activities by writing 680MB of files onto the hard disk.

Maybe we should do a RAID 5 test only.....the RAID 0 results are what you expect them to be at this time, very good in two system benchmarks but slower in a couple of games..... ;->

Two articles with raid numbers.

The THG review only compares a single 150 Raptor to a RAID 0 with slower drives, but it does use a few real-world benchmarks. The other review tests RAID 0 with these Raptors but only uses synthetic benchmarks. Synthetic benchmarks are useful, but they are only part of the performance picture. Results with real-world benchmarks - particularly in RAID 0 - are very different.Live - Wednesday, February 8, 2006 - link
The tests linked are not very good. GamePC uses synthetic benchmarks which are not indicative of real world desktop performance. The Iometer in particular is not useful for single user scenarios and never was. Basically Gamepc doesn’t know what they are doing (or since they sell the stuff maybe that’s just what they do...)We all RAID-O improves performance a lot in Synthetic benchmarks. It does however not do the same for real world tests and certainly not in a cost effective way. I highly doubt SATA or this new raptor changes that. But would be interesting nonetheless to see some tests on the matter.

This is the best hard drive review I've seen on AT in a very long time. Great job, guys. The history of Raptors at the start was a nice touch to help me better understand what WD is doing. I also think this is the first drive review I have seen by Gary Key. Bring us some more like this one.Live - Wednesday, February 8, 2006 - link
I have to agree this was really a step up as far as hardrive reviews go. Nice to see you are improving your thermal and acoustics testing. Keep up the good work!!!Rolphus - Wednesday, February 8, 2006 - link
Agreed - great review, and it was really interesting and useful to get an understanding of the evolution of the product.My only question is, why wasn't Raptor+NCQ added as part of the multi-tasking tested? I can see that being a useful indicator of desktop performance, especially as dual-core CPUs become more prevalent.

That would be multi-tasking tests. Only had one coffee so far.Gary Key - Wednesday, February 8, 2006 - link
We will be investigating the effects of NCQ in more detail in the near future. We are working on a revised benchmark suite that consists of more real world applications and varying multi-task scenarios.ohnnyj - Wednesday, February 8, 2006 - link
In some of the graphs there are two 74GB Raptors, are these two different revisions?John
