Solidigm P41 Plus 1TB 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.

4K Random Read.

In our lower queue depth, 4K random read tests, the performance increases steadily as the queue depth deepens for each thread. At QD1 the performance ranged from a low point of 18,937 IOPS (77.56MB/s) for a single thread up to 69,705 IOPS (285.51MB/s) for four threads. At QD8 a single thread produced 111.732 IOPS (457MB/s), two threads 162,231IOPS (664MB/s), three threads 191,514 IOPs (784MB/s) and finally with four threads, 205,450 IOPS (841MB/s).

4K Random Write.

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