Hard Disk Interface
ATA Full Name Advanced Technology attachment, is the traditional 40-pin and port data cable connection between the motherboard and the hard disk, the maximum external interface speed of 133mb/s, because the same line of interference is too poor, and line space, adverse computer cooling, will gradually be Replaced by SATA.

Introduction to Interfaces
IDE interface
(Integrated-drive-electronics) is now commonly used external interface, mainly connected to the hard disk and optical drive. Using 16-bit data parallel transmission mode, small size, fast data transmission. An IDE interface can only receive two external devices.

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.
