I have a Samsung 970 EVO 500GB with an average read rate of 3.2 GB/s and average write of 292 MB/s. I know it says speeds are "up to" 3500/2500 MB/s but there has to be something wrong with my write speed. Don't have any NTFS partitions on it so can't check it with Samsung software, although other drive software(sk hynix) shows it as good and healthy from an external windows.. I don't know how to find the issue, the limited info I got from nvme-cli and smartctl aren't showing anything that helped me. I've included nvme smartlog and inxi output and link to gnome-disk-utility benchmarks with diff size samples. Can someone help me find where the issue is ?

For OS I use an Ubuntu Cinnamon remix that I built from source as a daily driver, the benchmark results are from LMDE4 that is installed on 2.5"SSD.
