  • ext4, which works - mostly - but is showing its age. The codebase terrifies most filesystem developers who have had to work on it, and heavy users still run into terrifying performance and data corruption bugs with frightening regularity. The general opinion of filesystem developers is that it's a miracle it works as well as it does, and ext4's best feature is its fsck (which does indeed work miracles).
  • xfs, which is reliable and robust ...s As who's both read and written quite a bit of filesystem code, the xfs developers (and Dave Chinner in particular) routinely impress me with just how rigorous their code is - the quality of the xfs code is genuinely head and shoulders above any other upstream filesystem. ...
  • btrfs ... Unfortunately, too much code was written too quickly without focusing on getting the core design correct first, and now it has too many design mistakes baked into the on disk format and an enormous, messy codebase - bigger that xfs. It's taken far too long to stabilize as well - poisoning the well for future filesystems because too many people were burned on btrfs...

edit: rémlik valami fuzzying teszt is ahol a btrfs másodpercek alatt vérzett el, ext4 percek,x meg órák alatt talán de most nem találom...
