    AHCI or RAID for new install?


    I’m going to reinstall Windows 7 on an SSD (120 MB) I just bought. I know I need to set the bios to AHCI mode for the SSD. I also have a RAID (2 x 250 MB 7200rpm) array I would like to use for data storage. I was going to install windows with only the SSD connected and then connect the RAID array. My problem is I can only set the SATA ports on AHCI or RAID. What do I set the bios on to have both installed? The MB is an Asrock 760GM-GS3.

    RAID is the same as AHCI but with raid features.

    Thanks Logicearth. Oh good, I was hoping that would be the case. Will TRIM still work for the SSD in RAID mode? I have read that TRIM does not work well in RAID mode.

    I believe that is only an issue if you are actually putti g the SSD into a raid configuration. If it is standalone shouldnt be a problem.

So I picked up a pair of Corsair Force 120Gb SSD drives and set them up in RAID 0. Figured I could just slap them in, load the AMD RAID drivers then do a clean install of Win 7. Which I’ve done and everything seems to be working fine. Now reading about the performance benefits when setting your...
