WD_BLACK SN850 2TB PCIe Gen4 NVMe SSD Review


AS SSD Benchmark

AS-SSD (2.0.7316.64247) Benchmark:

We have been running the AS-SSD Benchmark app for over some time now and found that it gives a broad result set. The programmer has worked very hard on this software and continues to make updates often so if you use it, show him some love and send him a donation. There are now three tests that are found within the tool and we’ll show the results from all three of them.


Benchmark Results: On AS SSD Benchmark, the WD_Black SN850 2TB drive topped out 5,777.27 MB/s read and 5,167.58 MB/s write with an overall score of 6,509 points. The 4K numbers were again solid at 68 MB/s read and 200 MB/s write.

AS SSD Compression:

Benchmark Results: For this benchmark chart you would ideally want to see a straight line as you dont want any compression performance loss as the test goes from 0% compressible to 100% compressible data during the benchmark test period. Things were pretty flat here on the read side, but there are obviously three big performance drops on the write side that we don’t like to ever see.
