A typical Android tablet's Micro SD card might be a Class 2, meaning it's guaranteed to write at 2MB/s. Most companies actually make the cards to exceed that expectation, sometimes by quite a bit. If you take huge amounts of pictures with your tablet, a Class 4 Micro SD card, which is just one class higher, might benefit you. It won't exactly be a life-altering experience, but it could speed things up if your tablet's camera takes pictures at something higher than 5 Megapixels. Most Android tablets don't do that. If you use the USB Storage feature of your Android tablet pretty frequently, then things are a bit different. When plugged into a computer as a USB storage device, the full capabilities of the card are used to transfer data—so the faster the card, the faster your data transfers. Most people might plug their tablet in to do this once a month to switch out their book, magazine, music, video or picture collection, so it's no big deal. If you use your tablet like this regularly, then the cost of a higher class card may be worth it, but will be your choice and the staff at your local store can help further.
