Ever heard of AHCI ? No?
In short, AHCI is a new hardware communication standard from INTEL that can speed up hard drive operations and enable more efficient multitasking. Since the release of Vista, Windows has natively supported what is known as AHCI (Advanced Host controller Interface). In most cases Windows does not recognize the ability to use ACHI. Usually because it has not been switched on in your BIOS. If you have at least one SATA disk on your system you may benefit from activating the AHCI driver. Before we get to that part, let’s explore what the ACHI is and what it does.
