Solidigm P41 Plus 2TB SSD Review

We used CrystalDiskMark 8‘s custom settings to test the drive's 4K random write performance 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 298,318 IOPS (1,221.91MB/s) at QD32 which is way off the official maximum figure of 540,000 IOPS.

4K Random Write v QD Performance

While we couldn't get close to the maximum quoted figure for 4K random writes with our testing, at QD's 1 and 2, the 2TB P41 Plus is the fastest 2TB consumer drive we've seen to date, but as the queue depth deepens past QD2, the drive slips down the result charts.
