I have the Samsung 960 Evo NVMe PCIe M.2 250GB, 6 days ago, when testing with userbenchmarks, it's results were the following;


Samsung 960 Evo NVMe PCIe M.2 250GB-$177
97,626 User benchmarks, average bench 199%
165GB free (System drive)
Firmware: 3B7Q Max speed: PCIe 5,000 MB/s
SusWrite @10s intervals: 627 328 329 326 326 326 MB/s
Performing way above expectations (99th percentile)
239% Outstanding

Now it's this;

Samsung 960 Evo NVMe PCIe M.2 250GB-$177
97,626 User benchmarks, average bench 199%
114GB free (System drive)
Firmware: 3B7Q Max speed: PCIe 5,000 MB/s

Performing way below expectations (2nd percentile)
121% Outstanding

Read 2,193

Mixed 421
SusWrite 142
159% 745 MB/s

4K Read 56.1
4K Write 2.2
4K Mixed 3.7
91% 20.7 MB/s

This system is only maybe a few years old.

The rest of the system is like this;

Any help would be appreciated.

No scans were running etc. I've tried the test multiple times with the same result. Was all good til about 6 days ago now.

Samsung Magician doesn't have diags, just benchmarks.
HD Tune comes up clean for it's health as in no errors found.

The M.2 windows partition still has 90GBs left of 167GBs.
The games partition of the M.2 drive has 21GBs of 65GBs left.
