"Works Great"

I formatted it when I got it, put it in my device and it has worked fine. Videos played on my tablet from it play fine and its write speed seems okay to me.

"Memoryalpha"

Seems like a good alternative to flash drive. Cost per gig seems like a pretty good deal, very convenient to carry around. I put my reading, music, pictures and videos on separate cards. Much more portable. Unfortunately smart phones and tablets are lagging.
