sata3.0标准协议

This specification defines a high-speed serialized ATA data link interface (specifying Phy, Link, Transport, and Application layers). The serialized interface uses the command set from the ATA/ATAPI-6 standard, augmented with Native Command Queuing commands optimized for the serialized interface. The serialized ATA interface is defined in a register-compatible manner with parallel ATA to enable backward compatibility with parallel ATA drivers. The physical interface is defined to ease integration (low pin count, low voltages) and enable scalable performance (with currently defined data rates of 1.5 Gbps and 3.0 Gbps).
