some results of my bonnie++ benchmarks
(after disabling tracker "tracker-processes -k"
and using "/usr/sbin/bonnie\+\+ -n0 -f -d." on different media)
I had to disable the file creation benchmarks as they were extremely slow on fat.

Code:

please replicate the tests on your device. there is noticeably variance.
