    Raid vs AHCI


    While experimenting with a USB bootable Macrium Restore thumb drive I created, I was looking in my Bios and noticed the SATA controller was set to Raid. I have only one internal HD.

    I changed it to AHCI and booted up, got a notice that new drivers were being installed and rebooted.

    The computer seems to be running the same. Wondering why HP had it set to Raid.

    So what is the difference between the two settings?

    I'd let AHCI if you just have 1 HD

    With only one drive AHCI and RAID perform the same, at least for Intel controllers.

    Thanks for the replies...

    I'll just leave the AHCI setting for the controller.
