Comment 3 for bug 891062

It looks like there is already a test filled in for sd-mmc, so I think this can be closed, *but* since it's still open and following on To kejun-zhou's recommendation about iozone, I think it might make a better test than simply copying some files over to the sdcard partition. However, I'm not sure we can set any minimum performance threshold since that's so variable on the sd card you use. Anyone have an opinion on it?
