I've heard there is an AHCI mode in SATA hard drives, but I do not know more about it, and how to enable AHCI to speed up hard drive performance in Windows 7, could you help me?
AHCI describes a PCI class device, mainly plays the role of an interfacein between the system memory and Serial ATA devices.
AHCI includs a PCI BAR (base address register) to achieve the native SATA function. As the AHCI successfully develops a unified interface,allow the Serial ATA product development work greatly simplified. It can achieve a number of features including NCQ (Native Command Queuing).
The Advanced Host Controller Interface(AHCI) will speed up read and write operations of the hard drive if the hard drive supports AHCI.
