SATA-II is a highly confusing marketing term. It is /not/ a technical
term.

In some cases there are NO differences between SATA-I and SATA-II. You
can find 1.5Gbps non-NCQ-supporting devices claiming SATA-II.

Similarly, there is no "SATA version" word in the IDENTIFY DEVICE page,
like there are "ATA version" words.
