Maxtor Atlas 15K 73GB
Western Digital Raptor WD360GD 37GB
|Operating System||Windows 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.
We used the following versions of our test applications:
- ZD Media Business Winstone 2004 1.0.1
- ZD Media Content Creation Winstone 2004 1.0.1
- Xmpeg 5.03 with DivX Video 5.11
- ATTO ExpressPCI Utilities v163
- Intel IOMeter v2004.07.30
- Xbit Labs File Copy Test v1.0 beta 13
- TCD Labs HD Tach v3.01
- Far Cry v1.2
- DOOM 3
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.
