I have two Maxtor 60gig, 7200rpm ATA133 drives in a RAID 0 config. It's a system with an Athlon XP 2100+, an MSI KT3 Ultra mobo with the Promise FastTrak 133 RAID controller. Most of the other stuff should be pretty irrelivent, but if anyone needs more info let me know. Anyway, my problem is that when I benchmark my hard drives they come up way less than a simple ATA66 7200rpm drive. I can't figure out why they are performing so much slower than they should be, I don't know what else to check. I did this benchmark with the SiSoftware Sandra program. If anyone has any ideas they would be greatly appreciated. Thanks
