ATA/ATAPI-5规范

ATA接口相关开发的标准-This standard specifies the AT Attachment Interface between host systems and storage devices. It provides a

common attachment interface for systems manufacturers, system integrators, software suppliers, and

suppliers of intelligent storage devices.

The application environment for the AT Attachment Interface is any host system that has storage devices

contained within the processor enclosure.

This standard defines the connectors and cables for physical interconnection between host and storage

device, as well as the electrical and logical characteristics of the interconnecting signals. It also defines the

operational registers within the storage device, and the commands and protocols for the operation of the

storage device.

This standard maintains a high degree of compatibility with the AT Attachment with Packet Interface

Extensions standard (ATA/ATAPI-4), NCITS 317-1998, and while providing additional functions, is not
