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?

    From arch wiki:

    Disabling CoW in Btrfs also disables checksums. Btrfs will not be able to detect corrupted nodatacow files. When combined with RAID 1, power outages or other sources of corruption can cause the data to become out of sync.

    No thanks

      that’s no different than any “normal” filesystem with a traditional block-level RAID solution

        Not really. You can still use dm-verity for a normal raid and get checksumming and normal performance, which is better and faster than using btrfs.

        But in any case, I’d recommend just going with zfs because it has all the features and is plenty fast.
