What filesystem is currently best for a single nvme drive with regard to performance read/write as well as stability/no file loss? ext4 seems very old, btrfs is used by RHEL, ZFS seems to be quite good… what do people tend to use nowadays? What is an arch users go-to filesystem?
btrfs is great for system stability because of snapshots. You can set it up to automatically make snapshots at a timed interval or every time you run pacman.
If something breaks, you can just revert to a previous snapshot. You can even do this from grub. It’s a bit hard to set up, so if you want, you could use an arch based distro which automatically sets it up like GarudaOS.
Too bad btrfs still doesn’t support encryption natively, unlike ext4.
How much is ext4 filesystem-level encryption actually used though?
I guess not much on desktop Linux, but every Android phone uses it. Really wish every Linux desktop would start encrypting their /home partition by default, which is the standard by many other operating systems.
I’m pretty sure default Android runs almost always on F2FS.
Android on many OEMs migrated to EROFS from F2FS for system partition.
