I want to learn more about file systems from the practical point of view so I know what to expect, how to approach them and what experience positive or negative you had / have.

I found this wikipedia’s comparison but I want your hands-on views.

For now my mental list is

  • NTFS - for some reason TVs on USB love these and also Windows + Linux can read and write this
  • Ext4 - solid fs with journaling but Linux specific
  • Btrfs - some modern fs with snapshot capability, Linux specific
  • xfs - servers really like these as they are performant, Linux specific
  • FAT32 - limited but recognizable everywhere
  • exFAT - like FAT32 but less recognizable and less limited
  • ghjones@beehaw.org

    As an aside, I’ve been watching bcachefs with some interest, as it seems to be getting faster with every kernel release, building on the data integrity guarantees of ZFS while pushing performance boundaries and being GPL compatible (i.e. in tree). Kent Overstreet et al. have done a fantastic job with this FS.
