I bought a generic SD card for my Galaxy S5 and it corrupted all of my music. I am glad I have this SanDisk because it is faster at reading/writing and comes with the MemoryZone Backup app free, however, you need to have Google Drive, Box, Dropbox, or a similar cloud service. MemoryZone is great at backing up but lost some of my data when doing a transfer (phone to SD) :/
