    So does this mean I can start using btrfs, at least for personal workstations? I've got a new box at the office waiting to be setup, with a 120GB Corsair SSD as the main system disk, normal 2TB harddisk as backup/media storage. Will be using Debian. Should I use btrfs?

      Short answer: no.

      Long answer: Please! The more people exercising the code, the more bugs will be revealed, and the more confident the developers can be. But you will have to be ready for some performance regressions and data loss danger. For the brave.

      Performance is still pretty bad, especially when deleting many small files. It can take minutes with BTRFS, while EXT4 does it almost instantly in comparison.

      I'm just one man, but I've tried hard over the past decade to find a real problem with NTFS (and I've been sternly bitten by ReiserFS and ext2/3 over that same period), and just haven't: It's worked on the many hundreds of computers I've fondled just fine, and even seems to survive mild hard disk failure with some amount of reasonableness.

      What, in your opinion, makes NTFS a pain in your ass? (I ask because I'm curious and want to avoid any such scenario, not because I am predisposed to attack your observations.)
