Lexar Professional NM800 Pro Heatsink 2TB SSD Review

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.

In our 4-thread 4K random read tests, the drive peaked at 355,040 IOPS at QD16 before dropping back to finish the test run at QD32 with a test result of 354,222 IOPS.

Random Read v QD compared.

The Lexar Professional NM800 Pro Heatsink sits in second place in our results tables at QD's 1 and 4 behind the HP FX900 Pro, a drive that uses the same InnoGrit IG5236 controller. At QDs 2 and 32, the drive sits in the bottom half of the table.
