test flash cards capacity and performance
f3 is a simple tool that tests flash cards capacity and performance to
see if they live up to claimed specifications. It fills the device with
pseudorandom data and then checks if it returns the same on reading.

F3 stands for Fight Flash Fraud, or Fight Fake Flash.
