Meaning of AHCI

What is AHCI?

AHCI stands for Advanced Host Controller Interface and is a technical standard defined by Intel that specifies the operation of SATA (Serial ATA) host bus adapters.
AHCI is present on Intel’s most technologically advanced chips. In addition, AHCI mode is enabled in the BIOS, where there are usually 3 available configurations: IDE, AHCI, and RAID. The AHCI and RAID settings require a storage device that contains the driver, so that it is included in the operating system installation (via the F6 key). If this does not happen, hard disks will not be detected.

This mode has the following advantages:

  • provides support to the Native Queuing Command (NCQ), enabling SATA units to accept more than one command at a time, increasing the level of efficiency;
  • offers support in hot-swapping ( hot plugging) devices;
  • gives support for staggered rotations between multiple drives when the operating system is booted.

In AHCI mode, the hard disk communicates with the rest of the system on the computer using a SATA storage controller. AHCI gives software developers and hardware designers a standard approach to the detection, configuration, and programming of SATA / AHCI adapters.
