I actually have an odd problem coming from the same setup. I'm running two 640GB caviar blacks in RAID 0 and just put a Force 3 60gb on it's own, on an EVGA x58 SLI. The odd thing is, on each boot, my RAID array randomly either 1. picks up the SSD and OS still fails to load from RAID 0, 2. doesn't pick up the SSD at all and then doesn't include one of the 640s in the raid (non member) meaning OS fails, or 3. picks up the SSD and decides to boot the OS from the raid.
I flashed BIOS prior to installing. No clue where to start here because once it's detected and I boot up, the SSD works fine. Just very touchy when I'm trying to power up.
