Advanced Technology Attachment ("ATA") is most closely related to disk drives implemented by integrated drive electronics technology.

IDE is a computer system interface, mainly used for hard disks and CD-ROMs. Its original meaning is "a hard disk that integrates the controller and the disk body." A few years ago, most of the hard drives used in PC hosts were IDE-compatible. They only needed to be connected to the motherboard or adapter with a cable. At present, the main interface is the SATA interface.

With the increasing development of SATA technology, motherboards without ATA have appeared, and Intel no longer supports the ATA interface by default in new chipsets. Host version manufacturers need to add additional chips to support ATA ( Usually for compatibility with older hard drives and optical drives).

Advantages and Disadvantages:

Low price, very good compatibility (IDE's cables adopt retroactive compatibility mode, new specifications of cables are compatible with old specifications of equipment, but if the reverse In the past, the cables of old specifications were not compatible with new specifications of equipment due to the problem of excessive noise ratio) and were slow (especially early ATA hard drives).

There is no USB-IDE conversion offline, it can only be used internally. There are strict restrictions on the length of interface cables, and most IDE cables are connected in parallel, so they are susceptible to interference from noise emitted by other lines in the PC (such as power cords, or CD-ROM audio cables, or other IDE device cables).
