Its a memory card. Works great so far.

So with this card you are definitely paying for the speed with almost twice the cost per GB of other similar cards. The U3 is just faster than the U1 cards and is probably only needed if recording in 4K or maybe HD burst photography. But all things considered this no-name brand is pretty cheap so I went with it and I am pleased. I have had no issues recording in HD with it and it works as needed.
