And btrfs is really frightening there.

  actually btrfs looks pretty good on the phoronix benchmarks (note that higher is better in all those tests - go look at the write tests) on Kent's benchmarks, something is up with the results in the thousands of MB/s - high end flash is fast but not that fast unless the entire transaction is possibly taking place in RAM cache instead of on the drive - which would explain btrfs having numbers in the hundreds of MB/s instead

    High end flash is that fast. Btrfs is simply not a good filesystem (yet?).

    Even mid range PCIe flash devices are fast enough to make the Btrfs numbers seem unreasonably slow.

      My experience with btrfs in the real world was that it was unreasonably slow. At least an order of magnitude slower last time I tested it (which admittedly was a year or 2 ago). I keep hoping they'll introduce some massive speedups but until then it's ext4 or xfs for me.
