Serial ATA<br />
Appendix C Serial ATA<br />
C.1 Description<br />
Serial ATA (SATA) is defined as the primary inside-the-box storage connection only, with no<br />
outside-the-box implementation. It is a storage device-centric technology and does not support<br />
other peripherals, such as cameras, scanners, or printers.<br />
The Serial ATA 1.0 specification outlines the following benefits:<br />
<br />
<br />
<br />
Performance Headroom: SATA provides higher performance than equivalent ATA with<br />
performance scaling from 150MB/sec at introduction and 300MB/sec in the second<br />
generation. It is ultimately forecasted to reach 600MB/sec during its anticipated 10-year<br />
roadmap.<br />
Software Transparency with Legacy Parallel ATA: This enables a relatively easy<br />
transition to the new technology.<br />
Low Cost: SATA is cost-competitive with equivalent Parallel ATA solutions, including<br />
hosts, devices, and cabling in volume quantities.<br />
