We used CrystalDiskMark 8‘s custom settings to test the 4K random read performance of the drive through a range of queue depths. The setup for the tests is listed below.

Transfer Request Size: 4KB, Outstanding I/O: 1-32.

Our four-threaded 4K random read tests couldn't get close to the official maximum of 1,400K IOPS. The best figure we saw was 520,556 IOPS (2,132MB/s) at QD16.

4K Random Read v QD Performance v QD

At QD1 the drive sits in third place behind both Crucial T700 drives but as the queue depth deepens it begins to drop down the chart so by QD4 it sits at the bottom of the results. However, by QD32 it has staged an excellent recovery as it sits on top of the table as the fastest Gen 5 drive we've tested to date at this queue depth using this particular test.
