We used CrystalDiskMark 8’s custom settings to test the drive's 4K 70/30 mixed read/write performance 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 fairly smooth curve from 23,901 IOPS (97MB/s) at QD1 up to 114,312 IOPS (468MB/s) at QD32. Using four threads the performance seems to ever so slightly slow down from QD4 through to QD8 before recovering to finish the test run at QD32 at 216,952 IOPS (888MB/s).
