i'm testing a RAID array now, there is a science to this stuff, and admittedly I have lost a bit of knowledge and know-how as XP has been my OS for quite sometime now....I've tried numerous BIOS settings for the HD controllers, AHCI, ACPI S1/S3, RAID-IDE...I've gotten rid of all hardware short of essentials....i don't have another system to benchmark it from since the systems I have are all 5+ years old (AMD X2 based, plain old DDR memory, SATA 1.5) the new tech is totally different...I'm comfortable with what I already had, but the games of today are lacking on my old systems.
