My latest build of a P5B DH Deluxe has 3 SATA drives. I run them all of my ICH7R chip. I installed XP Pro using F6 where I installed\nthe RAID driver for the ICH7R and it went smoothly.\n\nI have 2 of the drives as RAID0, which is my C: boot drive. I then have a 3rd SATA drive as a single, IDE type drive also running\noff the ICH7r.\n\nMy question is, should I also have loaded the AHCI driver for this single drive? I'm assuming that since I only loaded the RAID\ndriver for the ICH7R when I installed XP Pro, that the 3rd drive is simply running in IDE mode.\n\nIs running the non-raid SATA drive in AHCI mode possible? Does it give added performance when accesssing that drive? Or should I\nleave things, which are running smoothly, as they are now?
