I'd like to know the specification of SATA-III.

Category : Specification / Capacity / Performance
The following SATA-III specification are provided by SATA-International Organization (sata-io.org) :
1. The maximum theoretical data transfer rate is up to 6Gb/s.
2. Data transfer power is lower than SATA-II.
3. Backwards compatible with SATA-I and SATA-II, but the data transfer rate will reduce to 3Gb/s and 1.5Gb/s.
Note: Speed may vary according to host hardware, software and usage.
Is the answer helpful?
