We test the Sequential read and write performance of a 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.

In our own Sequential tests, we saw a peak read score of 6,605.98MB/s (QD32) which confirmed the official read figure. The best-tested write result was 5,001.57MB/s (QD4) again confirming the official 5,000MB/s.

128KB Sequential Read Performance v QD compared.

At QDs 1,2 and 4 the drive sits in the top five of the Sequential read results charts but at QD32, the drive sinks to the bottom half of the table.

128KB Sequential Write Performance v QD compared.

In contrast to the Sequential read results, the Sequential write results see the drive positioned in the bottom half of the results charts throughout the tested queue depths.
