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.

In these Sequential tests could confirm the official read rating of up to 7,250MB/s with a result of 7,281MB/s however the write result wasn't as strong at 5,916MB/s, some 384MB/s short of the official maximum write figure.

128KB Sequential Read compared.

At QD1 the drive sits in seventh place in the Sequential read chart just above the Samsung SSD990 PRO. At QD2 it has slipped down the chart before staging a recovery at QD4. By the end of the test run at QD32, it has slipped out of the top 10.

128KB Sequential Write compared.

When it comes to Sequential write performance, the drive doesn't do as well, sitting in the penultimate place in the table at QD1. It doesn't really improve much as the QD deepens.
