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, the read performance dropped sharply at QD8 but the drive recovers very well to finish the test run at 4,191.24MB/s, confirming the official figure of 4,150MB/s. No such performance worries with the write performance which is pretty consistent from QD2. The test run finishes with a write result of 4,168.8MB/s, again confirming the official figure.

128KB Sequential Read v QD

In relation to other drives around it, the WD Blue SN580 performs best at QD2 followed by QD1 in our Sequential read test. As the queue depth deepens the performance falls back.

128KB Sequential Write v QD

In our Sequential write test, the best performance from WD's Blue SN850 came at QD1. As the queue depth deepens the performance drops off sharply.
