The numbers are indeed much better: MB/s Runtime (s) ----- ----------- btrfs-unstable 17.09 572 The disk is capable of 40+ MB/s however the test partition was one of the last ones and as I figured it out now, it can do only 26 MB/sec. Btrfs bulk write easily sustains it. The write speed was 21 MB/s during the benchmark, so btrfs is the closest to the possible best write speed in the test environment.
