Btrfs gets a bad rap sometimes but I have been using it for years and it works very well. It is able to take failing hardware and power outages and still has good performance.
Its supposed to be called betterFS but Jim Salter keeps calling it butter FS. Doesn't really inspire confidence. At least it's gonna need.. a better name
Jim Salter, the former mod of r/zfs ? Former Ars Technica ? Currently in the ' 2.5 Admins' podcast?
He's the hot knife of butter FS.
Ok that still doesn't ring a bell but he seems important to you so that's good enough for me
