I was surprised to see the main drive in my Dell Venue Pro 8 was almost completely consumed by the Windows OS.  I added this card to create some space for myself.  The tablet recognized it as an additional disc with 29GB available.  That gives me plenty of breathing room for what I do with the tablet, and the speed is incredible.  I am very pleased with this product, and will purchase another one when I upgrade the card in my GoPro this summer.
