Moving on, Crystal Disk Mark 8.0 is our next benchmark. For a bit of background information, higher capacity drives tend to perform a little better in these tests. The ability of a controller and flash memory to deliver high IOPS will provide huge benefits to the score as well.

Lexar claims the NM800 PRO 2TB has maximum read and write speeds of 7500MB/s and 6000MB/s, respectively. Looking at the read and write results, the NM800 PRO 2TB was not able to reach the maximum quoted read speed, but it did surpass the write one. Even so, when we compare with other PCIe 4.0 NVMe drives, it was in the upper half for the sequential read test, while placing just behind the ADATA Legend 960 1TB in the write portion. The Seq1M Q8T1 was a similar story, with the read portion ending in the middle of the pack, but the write test came in first place. This impressive write performance continued a trend we have seen from other benchmarks. As for our random tests, the Lexar Professional NM800 PRO 2TB was able to flex its muscle more. In the RND4K Q32T1 tests, the NM800 PRO 2TB was only barely behind the WD_BLACK SN770 NVMe SSD 1TB for write, while staying far ahead of everything else for read. Moving to the RND4K Q1T1, you can see the NM800 PRO 2TB was in the lead for both read and write.
