USB Flash Drive File-System Tests On Fedora

First up was the widely-loved Flexible I/O Tester (FIO).

With carrying out random reads, there wasn't a huge performance difference for this Lexar USB 3.0 flash drive with the speeds of the four tested file-systems coming in at 5~6 MB/s. In raw numbers, XFS was the fastest at 6.94MB/s.

With sequential reads, Btrfs was slower than the rest while XFS again had the highest performance at 20.63MB/s.

When switching over to writes, for sequential writes the EXT3 file-system was much slower than Btrfs, XFS, and EXT4. EXT4 was slightly faster than the rest at 19.16MB/s.
