Operating SystemWindows XP Professional SP2 with DirectX 9.0c

The Serial ATA and SCSI cards were used in different PCI-X slots on different PCI-X busses. Each card had an entire PCI-X bus to itself, so bandwidth sharing won't be an issue.

A special thanks goes out to the Computer Repair Shop and KickAss Gear for kicking in the Western Digital Raptor WD360GD and WD740GD we used for testing

We used the following versions of our test applications:

The test systems' Windows desktop was set at 1280x1024 in 32-bit color at a 75Hz screen refresh rate. Vertical refresh sync (vsync) was disabled for all tests. All of the 3D gaming tests used the high detail image quality settings.

All the tests and methods we employed are publicly available and reproducible. If you have questions about our methods, hit our forums to talk with us about them.
