Are SATA 1, 2 and 3 cables interchangeable?

  • 772

I've got an older SATA drive (not sure if it's SATA 1 or 2). Same size plug as my new SATA 3 M/B.

Are the cables interchangeable? Any decrease in performance from using a "lower" cable?

    Normally nothing has changed between the cables between SATA I,II and III. From the official SATA-IO document:

    The same cables and connectors used for current SATA implementations can be used to connect SATA 6Gb/s devices. SATA-IO recommends utilizing quality components to ensure data integrity and robust operation at the fast 6Gb/s transfer rate. Cables already at the threshold of 3Gb/s operating margins may experience lower performance than expected at 6Gb/s due to an increased number of resends.

    You can have a look at some benchmarks here.

  2. Yep. They're interchangeable. All SATA is backward (and forward) compatible.
