1.3SATA Interface

•The Serial ATA (SATA) interface is compliant with the SATA IO Serial ATA specification, revision 2.6 that supports SATA up to 3Gb/s.

•The SATA interface connects the host computer to the SSD subsystem.

•The SATA interface runs at a maximum speed of 3.0Gbps (Giga-bits per second). If the host computer is unable to negotiate a speed of 3.0Gbps, the SATA interface automatically renegotiates to a speed of 1.5Gbps.

For a list of supported commands and other specifics, please see Chapter 5.
