Serial Advanced Technology Attachment (SATA) is a computer bus primarily designed for
transfer of data between a computer and storage devices (like hard disk drives or optical
drives).
The main benefits are faster transfers, ability to remove or add devices while operating (hot-
swapping), thinner cables that let air cooling work more efficiently, and more reliable operation
with tighter data integrity checks than the older Parallel ATA interface.
SATA 1.5 GB/s and SATA 3 GB/s
SATA is designed to be backward and forward compatible with future revisions of the SATA
standard.
External SATA
Maximum cable length is 6.6 Ft (2 meters). USB and FireWire allow longer distances.
