I have a problem... I have 2 IBM 40gb drives in RAID 0 on my a7v133 running Windows XP. I am running the new expert bios 1010 beta, along with the fasttrack 2.00.34 drivers here. I have a few questions regarding my setup.

First, should I enable the "load onboard ata bios" setting in my bios? The last time I tried this, the fasttrack bios detected a problem with my raid array. If I dont load the ata bios, XP boots with no problem, and I can read from and write to the RAID array.

Second, benchmarking my drive gives VERY VERY different results depending on which benchmark program I use. Using HD Tach, it shows a bust speed of around 70-80 mb/s. This seems about right, I believe. Then I tried Sisoft sandra's file system benchmark. I got 5.4 mb/s... WHAT THE HELL???? I then tried ATTO's benchmark, the write speads seem correct, but the reads get gradually faster, where it will reach around 300 mb/s!! Something is screwy... I need to know if I'm getting the proper performance, and having 3 different benchmarks give 3 COMPLETELY different results isn't helping me

Please help!!! Thanks guys

(PS, I've also tried getting help at braziliantech.com, but to no avail)

Anyone??

I've just about given up on it, but it is highly frustrating. Is it a limitation with the drives themselves? They are ata100 and, as far as I can tell, operating at that speed according to windows.
