J.D.

The NCQ feature is enabled/disabled via software.  (Obviously the
drive has to support it before it can be enabled.)

The Linux Kernel is not likely to enable it by default since it is the
kernel developers doing the benchmarking, but they will implement some
way to enable NCQ for those users that have an appropriate workload.

So, you can decide if you want NCQ independent of the SATA 300 vs.
SATA 150 choice.
