HDD SATA speed setting

Kuntau asked:

I just noticed this info from smartctl

Does that mean I’m running inferior SATA II speed?

If yes, how do I enable SATA III speed?

My answer:


That old WDC hard drive only supports SATA II. So while your old computer might support SATA III, depending on which storage controller card you have, it can only talk to the drive at 3Gbps. To get SATA III speeds, you will need to replace the drive with one that supports SATA III (and check the storage controller as well).
