edit 2: Found a video by “SpaceRex” on the differences between BTRFS and EXT4, super helpful! He explained it quite well…
edit: It seems that there isn’t much difference between btrfs and ext4 aside from additional features of btrfs, which although I might not need right now, there doesn’t seem to be any harm in using btrfs over ext4, so I will be using btrfs.
Which would be better? Fedora shipped with btrfs, does it have any additional features that are good (quick search shows compression, subvolumes, and snapshots as main selling points for btrfs, but are there any downsides?
BTFS snapshots are such a huge improvement and a live saver if you like to tinker on your system. Also great for backups, which you should make. Use snapper and similar tools.
I’d only recommend ext* for spinning hard drives. For ancient slow machines, go with XFS or ReiserFS (if any distro still supports that even).
