Lexar NM790 with Heatsink 4TB SSD Review

We used CrystalDiskMark 8’s custom settings to test the 4K 70/30 mixed read/write performance of the drive through a range of queue depths using a single thread and four threads.

Using a single thread the performance of the drive ranges from 23,829 IOPS (97.60MB/s) at QD1 up to 215,017 IOPS (880.71MB/s) at QD32 in our 70/30 read/write tests. With four threads the performance goes from 99,387 IOPS (407MB/s) at QD 1 up to 567,808 IOPS (2,325MB/s) at QD32.
