Western Digital WD2500JB and WD2500JD HDDs
WD hard disk drives have the supported interface type marked with the last letter of the model name: 2500JB supports ATA/100 interface, while 2500JD is a SerialATA drive.

These are all our testing participants for today. Now I have to say a few words about the testing methodology to be used, because it will differ a little bit from what we are usually applying.
Testbed and Methods
Well, trying to meet numerous requests for a testbed upgrade we did our best and today we are proud to introduce our new test system to you:
- Albatron PX865PE Pro II mainboard;
- Intel Pentium 4 2.4GHz CPU with 533MHz FSB;
- 256MB PC2700 DDR SDRAM;
- IBM DTLA 307015 system drive;
- ATi Radeon 7000 graphics card;
- Windows 2000 Pro SP4;
- Promise Ultra133 TX2 controller;
- Promise SATA150 TX2Plus controller.
We still used the same tests for our investigation:
However, we are going to use them in a bit different way this time. If you are following most of the hard disk drives reviews and benchmarks, you may have noticed that many web-sites and offline magazines offer a more or less standard similar pattern set for Intel IOMeter and standard approach to WinBench. Therefore, I thought it would make sense to make a few changes to our hard disk drive testing methodology.
We will be testing every hard disk drive in WinBench99 for each file system: in a 32GB partition (when the logical drive is created in the beginning of the disk) and in a partition as big as the whole drive. All WinBench99 tests were run 7 times each and then the best result was taken for further analysis.
The second innovation in our testing methodology has to do with WorkStation pattern. In fact, the pattern itself remained the same, but the testing approach has become different. To evaluate how big the “locality” influence on the HDD speed is, we ran the pattern twice: on the entire hard drive and on the first 32GB of the drive.
The third innovation touched upon the FC-Test. Now I am not just cutting the drive into two parts of equal storage capacity but I am creating two partitions in the beginning of the drive with 32Gb storage space in each.
The synthetic patterns for Intel IOMeter and the server patterns remained unchanged. The HDDs didn’t cool down between the tests.
The testing participants had the following firmware versions:
