Please add the test case for SD/MMC ASAP.Thank you.

There is a test case for SD card on Snowball.

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?

FIO test case fixes it

@Chase, FIO is for ubuntu but this issue here is for Android.

We do have SD-MMC test automated on Android, not including performance part though:

As we currently have no request on performance test for Android, this bug can be closed anyway.
