FEATURES:
Serial ATA is an evolutionary replacement for the Parallel ATA physical storage interface.
Configuration of Serial ATA devices will be much simpler with many of today's requirements on jumper and settings no longer needed. Serial ATA supports all ATA and ATAPI devices including CDs, DVDs, tape devices, high capacity removable devices, zip drives, and CD-RWs.
Reductions in voltage and pin count. Smaller easier-to-route cables and elimination of the cable-length limitation.
Improved data robustness.
Backward compatibility.
