SATA
SATA stands for Serial Advanced Technology Attachment.
SATA II (revision 2.x) interface, formally known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 300MB/s.
SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a third generation SATA interface running at 6.0Gb/s. The bandwidth throughput, which is supported by the interface, is up to 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface.
SATA Revisions
- SATA rev 1: 1.5 Gbit/s - 150 MB/s
- SATA rev 2: 3 Gbit/s - 300 MB/s
- SATA rev 3: 6 Gbit/s - 600 MB/s
The Serial ATA International Organization (SATA-IO) is the group responsible for developing, managing, and driving adoption of the Serial ATA specifications.
Serial ATA host-adapters and devices communicate via a single high-speed seven-wire serial cable instead of a parallel bus used in previous technologies.
The Serial ATA host controller interface (AHCI) specifications describe the register-level interface for a host controller for Serial ATA. The specification includes a description of the hardware/software interface between system software and the host controller hardware, and is intended for hardware component designers, system builders and device driver (software) developers.
