Re: Z68 Extreme3 Gen3 UEFI Setup questions about "Storage Configuration", SATA/IDE/AHCI, etc.
I don't think you will see any performance difference using a mechanical/magnetic drive. The benefits of AHCI are mostly geared toward SSDs (Solid State Drives).
I would say the only real benefit to using AHCI with standard drives is for the hot-plug ability (plug/unplug hard drives and using them without needing to restart the computer).
From what I've read you won't notice any speed difference between either mode on a mechanical drive, like the one you have. You need a solid state drive to see a performance increase using AHCI, I would say.
AHCI is newer technology, so IDE mode is probably more stable if you don't need the features AHCI provides. If you ever plan on upgrading your OS drive to an SSD, and plan on cloning the drive to your new drive with clone/backup software instead of doing a fresh install, then it might make the process smoother if you already have AHCI enabled in Windows.
However, I highly recommend doing a fresh Windows install if you ever upgraded your OS drive to an SSD.
