PyNVMe3 Test Report of ADATA S50Pro
S50Pro performance is not good, especially when the drive is filling up, the sequential write performance is only 100-200MB/s.
|10% filled (MB/s)||50% filled (MB/s)||90% filled (MB/s)|
Its random write performance is very low.
|10% filled (K IOPS)||50% filled (K IOPS)||90% filled (K IOPS)|
And the performance cannot be recovered by idle, when the SLC cache is expected to be reclaim.
Even trim operation cannot speed it up.
|IOPS (K)||Average Latency (ms)||performance before trim (MB/s)||performance after trim (MB/s)|
There are too many long-latency IO in the test.
Lots of PyNVMe3 conformance test cases fail on S50Pro, and drive lost.
