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
Wasn’t that the entire purpose of ext4 vs ext3? As the default, I also keep journaling on for ext4 partitions. Even /boot.
ext3 had journaling, but not ext2. Also ext3 doesn’t really exist anymore as it was merged into the ext4 driver which can read the old format.
