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.

This table shows the real speed of SATA 1.5 Gbits/s and SATA 3 GB/s:
