Good to know:
✔ If the sd card is formatted as adoptable storage, the app may unable to access it directly. In that case either move the app to the adoptable storage (change the install storage), or format the storage as portable storage.

Common reasons: fake sd card, slow sd card reader/hardware problems of the phone, software problems.

Works as described, will give a quick test of memory performance. Free version won't work with internal memory configured SD cards. I also compared it against doing it manually with a stop watch and its spot on. The Read performance, is Read to app or RAM memory which is fast than real world, its read to another storage device, which is written to and slows the actual transfer down. Would recommend to anyone wishing to test new SD cards to prove its performance or new hardware.

Will not read my sd card after I gave the app permission to access my sd card a pop up read permission was denied. Total waste of time but the pop up ads work real well.

It's a good app get loads of information about your SD card and test speed. If you get an error reduce the size of the files that's been read and write. I got an error but I made the file size 1000 MB and then no more error. If you get a error probably you do not have enough space on your SD card so just make the file size smaller
