I bought this to stash all (the ones I would watch on the go) the movies and songs that I previously owned to my new Galaxy S4. I am extremely impressed with how fast the device works outside of the phone and inside when used by the phone. It is dramatically slow when the phone with the sd card in it is wired up to the computer via usb, but that is really unrelated and the process isnt painstaking. Fast and huge in capacity, definitely a must for enthusiasts.NOTE: As of ICS, Android has stopped allowing the movement of apps into the sd card. So if youre planning on installing games onto the card, you will need to have a rooted phone. The card is very useful for other things (music and video, and ROMS if youre interested) even then.
