Tip T5207 - Consider using the File Systems instead if the device is non-Flash based. As there is no reliable way to know the physical type of the device, it is left to the user to use the correct benchmark.
Fix: This benchmark has been optimised for solid state (Flash) media, and thus will not yield correct results on other devices. Such devices have negligible seek times and are transfer-speed bound, generally by the interface (e.g. USB 1.x). This is not the case for magnetic based devices like floppies, hard disks and tapes.
