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 four threads the Professional NM800 Pro heatsink peaks at QD16 with 328,370 IOPS (1,345.01MB/s) before dropping back slightly to finish the test run at 327,702 IOPS (1,342.27MB/s) at QD32.
Using a single thread the drive also peaks at QD16 at 109,408 IOP (448.13MB/s) before, just like the four-threaded test, drops back to finish the test run at 109,281 IOPS (447.61MB/s).
