Would you please publish the BIOS and Firmware versions you used on the Promise SuperTrak ex8350? I own this card and I am running the following versions:
* BIOS v220.127.116.11
* Firmware v18.104.22.168
I would also like to know if you would consider re-running the tests using the storport drivers for the Promise card. I believe these will only work on Windows 2003 Server so you would have to upgrade your base system from Windows 2000 sp4 (which seems antiquated). I am running the 64-bit edition of Windows 2003 server I show a serious improvement in performance using the storport drivers along with the BIOS and Firmware versions listed above.
