We used CrystalDiskMark 8‘s custom settings to test the 4K random write 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.

The Maxiotech controller is rated as up to 1,000K IOPS for random writes. As with the random read results with our 4-threaded tests, we couldn't get close to this figure with the best test result of 497,150 IOPS at QD32.

4K Random Write v QD Performance

At QDs 1, 4 and 32, the Lexar NM790 with Heatsink sits in third place on the results chart while at QD2 it drops a place to fourth.
