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 P41 Plus's performance climbs in a smooth curve from 22,520 IOPS at QD1 up to 108,952 IOPS at QD32. When tested using four threads the performance seems to plateau from QD4 through to QD8 before recovering to finish the test run at QD32 at 166,201 IOPS.
