Btrfs with FIO random reads is much slower than the rest with this high-performance Intel SSD.

Random writes were also slower with Btrfs while EXT4 was the fastest along with F2FS followed by XFS.

F2FS and EXT4 were the fastest in discard/nobarrier modes or XFS out-of-the-box with these sequential reads using a 2MB block size.

Or sequential reads with a 4KB block size show much closer performance figures.
