My NVMe disk works but it is very slow compared to what it was. I benchmarked it 6 months ago at 2000MB/s using fio, the exact same test now is giving me 350MB/s
I ran smartctl but it's giving a 0x2002 status.
Is my disk broken? Can it be repaired or do I need to buy a new one?
$ sudo smartctl -A /dev/nvme0n1p2
smartctl 6.6 2016-05-31 r4324 [x86_64-linux-5.0.0-37-generic] (local build)
