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
Ext4 for everything when possible, because its reliable and proven. I’m looking towards Btrfs for my next system drive, as it is mature now and has good features. But I would use Ext4 for everything else still. For interoperability that doesn’t understand Ext4 it would be NTFS when supported, otherwise fallback to FAT32.
That’s the entirety of my knowledge and what I use when I have to format it myself. :D
I respect your reliable and proven comment. I really love the features of BTRFS and that’s why I use it, but I also really care about my data. I have secondary installations that use EXT4 and work very well.
