ok my goal is to boot windows 7 x64 with raid-1. My boot drive is a SSD, which is not part of the raid array. I have 3 seagate ST2000DM001 that I want in raid-1. I have tried installing windows 7 with ahci in bios first but no luck. I was able to boot from raid1 when I started bios out in raid but my ssd drives read/write speeds significantly decreases. Any suggestions would be greatly appreciated.
