AHCI describes a PCI class device that plays the role of an interface between system memory and serial ATA devices, and is common to different operating systems and hardware.

In the AHCI 1.0 specification, Intel introduces the NCQ (Native Command Queue) feature and hot-swappable technology. The hard disk supporting the NCQ technology will reorder the access address according to the instruction, reduce the reading time, make the data transmission more efficient, and prolong the service life of the hard disk effectively.

AHCI technology requires both hard disk and motherboard support. For the hard drive, the AHCI 1.0 product is not fully supported, but some of the hard drives already support the NCQ feature and can be implemented with a motherboard that supports AHCI.
