Solidigm P41 Plus 1TB SSD Review

We used CrystalDiskMark 8‘s custom settings to test the 4K random write performance of the drive through a range of queue depths. The setup for the tests is listed below.

Transfer Request Size: 4KB, Outstanding I/O: 1-32.

The best random write figure we saw in our 4-threaded random write test was 247,641 IOPS (1014.34MB/s) at QD32 which is way off the official maximum figure of 520,000 IOPS. We did a quick test at QD32 using 8 threads and got a result of 420,582 IOPS, still short of the official maximum.

4K Random Write QD Performance compared.

At QD1 the drive sits in mid-table and as the queue depth deepens the drive slowly falls down the chart so by QD32 it sits in the bottom half of the table.
