AHCI (Advanced Host Controller Interface) is present on newer Intel chipsets. AHCI mode is enabled in the BIOS where 3 settings are commonly available: IDE, AHCI, and RAID. The last two (AHCI and RAID) require a floppy disk with the driver that can be introduced into the operating system installation through F6. Otherwise, the hard disks won’t be detected.

AHCI mode has 3 main advantages:

Supports NCQ (Native Command Queuing) allowing SATA drives to accept more than one command at a time and dynamically reorder the commands for maximum efficiency.
Supports hot plugging of devices.
Supports staggered spin ups of multiple hard drives at boot time.

When it comes to performance, there really isn’t a big difference in using AHCI.

Note: If you installed Windows in IDE mode (which means that you didn’t use F6 and supply a driver disk), then simply changing the BIOS setting to AHCI mode and rebooting will cause Windows to fail and will require a repair install. Most people are advising to reinstall Windows if you want AHCI enabled. (More information on AHCI)
