Solved Enabling AHCI On Seagate SATA Hard Disk Drive

  • 3

I have Asus P7P55d-E LX mboard & I would like to utilize AHCI on my Seagate SATA hard disk drive. In my BIOS setup I found 2 configurations regarding AHCI. [1] under ‘Storage Configuration’, Enhanced SATA with the option to set as IDE (default), RAID, AHCI; and [2] under ‘Onboard Devices Configuration’, Marvell 9123 Controller with the option to set as DISABLED, IDE (default), ACHI. Do I set both configurations to ACHI to achieve performance increase in my storage device? Note that AHCI support is enabled by default in my OS in the Registry. Thank you for your time.

      I understand your frustration. That said, the difference in performance in practice is minimal. The specs of the SATA drive are probably just as important as running in AHCI mode vs. IDE.

      If you ever need to perform a fresh install that would be the time to change the setting.
