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?
I usually just use EXT4, but perhaps you should check out F2FS. It’s designed for solid state storage mediums, as while most were created with traditional spinning hard discs in mind
I’ll suggest XFS.
