yah absolutely ext4 has progressively had its&#x27; performance reduced because what made it faster than ext3 created a lot of corner cases that make it far less reliable, and Btrfs is at least a fresh design, but doesn&#x27;t seem to be particularly ready and is not even proven as a reliable design.<p>It&#x27;s good that we have more than one filesystem.  HFS+ functionally works well for a Mac because the Mac is designed around it, but it is part of the reason that OSX falls short as a UNIX at times.
