"Ok, a little while back I ran a somewhat large USB Flash Drive Comparison with 21 drives compared, today I got part two of that comparison. I've taken the 8gig and 4 gig drives, nine in total, and formatted them FAT32, NTFS and ExFAT and ran all of the tests over again for a comparison of how the file systems work on the drives." Good news — after some exhaustively graphed testing scenarios, the author comes to a nice conclusion for lazy people, writing "[I]n my opinion the all around best choice is FAT32, or the default for most all USB drives out there today, it seems to give us the best average performance overall."
