We used CrystalDiskMark 8‘s custom settings to test the Sequential read and write performance of the drive through a range of queue depths. The setup for the tests is listed below.
128KB Sequential Read / Write.
Transfer Request Size: 128KB, Thread(s): 1, Outstanding I/O: 1-32.
When it came to Sequential read performance, the drive's performance levelled off at QD8 finishing the test run at QD32 just 4MB/s faster at 3,562MB/s, which confirms the official maximum speed rating of 3,500MB/s.
The Sequential write performance fell away at QD4 but recovered by QD8. The drive's performance peaked at QD16 with a result of 2,595MB/s before dropping back very slightly to finish the test run at 2,593MB/s. Both of these figures are some 400MB/s faster than the official write maximum of 2,100MB/s.
128KB Sequential Read v QD performance compared.
The NV2's best performance in the queue depth tests came at QD2 where its result of 2,766MB/s puts it in the top half of the 1TB class consumer drives we've tested to date. As the QD deepens the drive slips down the chart.
128KB Sequential Write v QD performance compared.
In comparison to the Sequential read QD results when it comes to Sequential writes, the drive stays firmly on the bottom of the performance graph through all the tested queue depths.
