EXT4 and F2FS were leading for FS-Mark while XFS fell back to last place.

With IOzone the results weren't too different between the file-systems on this USB flash drive.

F2FS was the fastest test for PostMark followed by EXT4.

Lastly, should you feel like running a PostgreSQL database from a USB flash drive for some reason, F2FS and EXT4 were the fastest.

Well, those are the results from this mini comparison. This weekend the four-flash-drive Btrfs RAID results should be completed and published.
