I use this in my Samsung Galaxy Note II. For the money, it's a fantastic value. I haven't noticed any transfer speed issues, and it's been rock-solid reliable for the 3 months I've owned it. I have about 32GB of music stored on it, and every app that can use SD card storage is set to do so, including all my system backups. The ultimate &#34;install and forget&#34; add-on for your phone!
