Solidigm P41 Plus 2TB SSD Review

We used CrystalDiskMark 8 to test the random performance of the drive at lower queue depths (QD1 – QD8 where most of the everyday workloads occur) using 1 to 4 threads.

Random Read

In our lower queue depth, 4K random read tests there are no unexpected shocks as the performance smoothly increases as the queue depth deepens for each tested thread. At QD1 the performance ranged from a low point of 19,720 IOPS (80.89MB/s) for a single thread up to 71,957 IOPS (294MB/s) for four threads. At QD8 a single thread produced 121.333 IOPS (496MB/s), two threads 184,323 IOPS (754MB/s), three threads 254,487 IOPs (1,043MB/s) and finally with four threads, 290,340 IOPS (1,189MB/s).

Random Write

In the 4K write performance tests the performance rose quickly from QD1 to QD2 but then levelled off for the remainder of the test run for all the tested threads.
