You know, ZFS, ButterFS (btrfs…its actually “better” right?), and I’m sure more.

I think I have ext4 on my home computer I installed ubuntu on 5 years ago. How does the choice of file system play a role? Is that old hat now? Surely something like ext4 has its place.

I see a lot of talk around filesystems but Ive never found a great resource that distiguishes them at a level that assumes I dont know much. Can anyone give some insight on how file systems work and why these new filesystems, that appear to be highlights and selling points in most distros, are better than older ones?

Edit: and since we are talking about filesystems, it might be nice to describe or mention how concepts like RAID or LUKS are related.

    Yes, but most filesystems are already optimized for flash storage. Arch wiki says f2fs is prone to corruption on power loss. Based on that and the lack of information on its anti-corruption measures I’m inclined to think it doesn’t have one and that’s why it’s faster. I wouldn’t use it in a non-battery operated device.

      So basically all laptop users can safely use it.

      Crazy how PC users rely on such a steady power supply. Arent there small UPS devices for a few seconds with auto shutdown?

        Catastrophic battery failure isn’t really any less likely than catastrophic power supply failure (conceptually. If you use a brandless grey power supply, results may vary).
