Without NCQ the SSD can only process one request at a time.Thanks. What would the benefits of NCQ be?
It wouldn't impact sequential speeds, but it would affect random I/O; especially random reads. You can see that in CrystalDiskMark and AS SSD as the random read qd=1 and qd=32/64 benchmarks would differ a lot with NCQ enabled; but would be roughly the same when using IDE mode which disables NCQ.
