I'm not a techie, so I can't do all those great experiments to determine whether or not the transfer speed is as advertised. All I know is, the card works just fine in my Galaxy S3. So far, it has worked great, and seems to be pretty speedy.I have San Disk cards in quite a few of my tech toys, and they've always performed well. I am confident that this one will do the same.
