Almost any brand would work. A very common one would be Sandisk, and they are pretty much everywhere. However I believe that device can only support a 128GB card. When searching I found two that say 128 and one that says 256. However one of those 128GB ones is on the Samsung site itself. So I would tend to trust that one more.
