Some SSD controllers, such as the later Sanforce models, do benefit from
NCQ with some server oriented workloads, little to none with others.
Controllers such as the Indilinx, Jmicron, and Samsung don't benefit
from NCQ at all, with any workload.
For a desktop user workload, there will be no noticeable performance
difference, because such applications don't do parallel IO.
