Not all SSD firmwares and controllers implement NCQ for writes, and for those that do, not all implement it well. The Samsung 470, the Kingston V+100, and the Intel 510 all perform relatively poorly for high QD writes. Interestingly, those are also the SSDs that have among the highest sequential write speeds.
