What are you trying to test exactly, the speed of the HW itself or the throughput that you get from a particular driver/implementation? The file-system on that media? The time it takes to wear off? What is it that you are trying to stress? > > I'm working on enhancing a script and so far, the only idea put forth > was to do multiple simultaneous read/writes (like 100 at a time).

Maybe for an SD card more realistic would be to transfer 3-4 MB files, but tons of them, like people do with cameras/music. Again back to my question of what you are trying to stress.
