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
I’ve only been put off with how slow it is in phoronix latest benchmarks
That’s fair, it has changed a bit since then and I’m hoping we get another filesystem benchmark to see if it has improved, and the caching features might offset that on frequently used data, but I don’t know how hard that would be to benchmark.

Oh, didnt know that was posted, some of the tests seem to be different from last time, it hasnt regressed but hasnt improved much yet either (from the ones that were the same). It does seem to have pulled ahead of BTRFS since the last test, doubling score in the DBench test, but it still varies a lot compared to the other filesystems it seems, doing worse pretty regularly.
