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
We use btrfs for the / partition and xfs for any data partitions. Has served us well, the snapshot feature saves us some valuable time when an update goes awry.
Why xfs let’s say over ext4? Just asking out of curosity.
The main distribution we use has it like that by default and our (admittedly rudimentary) benchmarks haven’t shown much of a performance difference versus ext4 so we kept to the default.
