    The BIOS for my Latitude comes with the ATA set by default, but the option exists for the drive to use AHCI. What are the differences? What is quicker?

    AHCI is the "Advanced Hardware Control Interface," which enables support for Intel Robson Turbo Memory. If you aren't using Turbo Memory, there is no advantage, and if you're running Windows XP, AHCI will actually keep you from booting.

    If you load the correct driver when installing XP AHCI mode is possible. The driver can be loaded after install but it requires switching to ATA mode in the BIOS. After installing the correct driver the machine can be switched to AHCI mode.

    I tell you what, i used both on my vostro. While using the ahci mode i got constant sound skipping. Ata mode has no skipping. So i use ata mode now.

    Sorry for bumping an old topic but i have some questions. :D

    Does the vostro have the turbo memory installed? If not are you able to upgrade it? How big is the benefit?
    I have it set to ata right now and i get sound skipping when on power saver mode... is there any connection?

    Edit: This is the reason i came here looking for answers... hard drive is the weakest link in my system.

    I don't know why, but I am able to boot my notebook even if I switch the settings in the bios from AHCI to ATA.
    I have confirmed with Intel Matrix manager that my HDD is actually in AHCI mode when it is selected. In ATA mode I can verify it in the device manager. I never faced any problem.
