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 this test, the read performance of the drive accelerates sharply from QD16 (8,579MB/s) to the end of the test run at QD32 with a result of 10,020.5MB/s. The write performance is much more consistent peaking at 10,186.2MB/s (QD8) before slowly falling back to finish the test run at 10,125.5MB/s.
128KB Sequential Read v QD Compared.
The drive tops the result charts through every tested queue depth by some margin although it must be said that WD'S Black SN850X Heatsink edition drive does narrow the gap at QD's 2 and 4.
128KB Sequential Write v QD Compared.
In the Sequential write test, the drive tops the charts by quite some margin at every tested queue depth. The closest any of the Gen4 drives gets is at QD1 where the WD Black SN850X Heatsink edition gets to within 1,371.22MB/s of Gigabyte's drive.
