Question Extremely bad write speed on NVMe SSD

[yyEDuu]

I got a Kingston NV1 1TB drive a couple months ago and everything was good until recently when i started having corruption and speed problems. Did a clean install of windows 11 but the problems persisted. SSD health is 99%, just 1300Gbs written. Sequential read speed is 2100Mb/s while sequential write speed is 12Mb/s.

What app did you use to get the results?

Did you use at least an other app for the test?

Used CrystalDiskInfo 8 and Kingston app for health info, for speed CrystalDiskmMark 8 and copying a large file from my hdd to my ssd also caps at 12Mb/s
