Publisher Description
Catch fake or flaky MicroSD cards before you lose valuable data
This "short" endurance test confirms if your SD card is valid and reliable OR if it's a counterfeit that has way less storage space than advertised. It fills your card with carefully designed files that the app can then verify to ensure that what's written to your flash card can be read back reliability. It also measures read & write speed at the same time, because, why not?
It's not the most pretty app because the focus has been instead on real-world testing and good algorithms. It is, however, easy enough to use. The only way to know your card is good is to fill it to the advertised capacity. Typically this takes less than an hour but can be longer if the card is particularly slow or enormous. Piece of mind is worth the wait and there are no shortcuts to it!
You can also test your phone's internal storage. With USB-OTG you probably can test thumb drives too, depending on how your phone works.
Note: English only. The default settings are reasonable, however, so you may just proceed to "start test".

Some users report that their card does not get detected. 1st, make sure your phone can see the SD card itself and has formatted it - the app can only see what Android itself can see and write to. 2nd, make sure the card is set as portable storage. If the card is still not accessible, please send beta feedback listing the proper path to your SD card (or USB flash drive over USB OTG ).
