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)

The SMART status may not be available for the namespace (n1) or partition (p2). Hence you must call it for the device itself:

smartctl -x /dev/nvme0

You can override the namespace to be queried for with -d nvme,$nsid, and 0xffffffff is the "broadcast namespace id". By default smartctl selects $nsid from the device node namespace id (in your case 1). So to query with broadcast:

smartctl -x -d nvme,0xffffffff /dev/nvme0n1p2

You need to run this: sudo smartctl -a /dev/nvme0

Try

smartctl -d nvme,0xffffffff -x /dev/nvme0n1
