In my dmesg logs I get following errors a lot:

I’ve run btrfs scrub start -Bd /home as described here. The report afterwards claim everything is fine.

It’s a
KINGSTON SA2000M81000G. Here is a “datasheet”.I’ve looked up some of the inode numbers in the logs and they point to some application state data in /var so reinstalling application could bring those files back.
I’ve never touched SMART before since I’ve assumed it’s an HDD thing. Anyway. I’ve installed smartmontools. nvme ssds don’t report smart stats like for hdds so this answer suggested looking for Percentage used in stead.
root@archiso ~ # smartctl -a --test=long /dev/nvme0n1 | grep "Used" Percentage Used: 2%It could be true that the firmware is not optimal but I could not find any news about that like you have for the 980. gnome software should keep firmware up to date in the background but just for good measure I ran it in live environment as well. I will probably get a new ssd at some point in the future and maybe use this old one for non critical storage in the future.
