USB Flash Drive File-System Tests On Fedora

When running one Dbench client, EXT4 and XFS were much faster than EXT3 and Btrfs.

Compile Bench showed more wins for EXT4 followed by XFS, but for these speeds were beyond the limitations of the USB 3.0 flash drive so there was some caching involved and not being entirely limited to the disk drive.

Overall from the tests ran in this simple file-system comparison on USB 3.0 flash drives, of the file-systems tested EXT4 did very well along with XFS. This is in terms of raw file-system performance but not looking at the reliability of the file-systems on USB flash drives. Also missing were F2FS, exFAT, and FAT32 due to the aforementioned reasons. This was just a small comparison but hopefully you'll find this data of some use, which can also be found on OpenBenchmarking.org. Those interested in the 64GB USB 3.0 Lexar flash drive that was used for testing, it can be found for just $20 USD at Amazon.
