Not much to say about the product , there is no configuration needed.it works out of the box, no need to format it unless if you want to.Speed? The tablet processor speed and the card make it impossible for you to see any delay. I am recommand it for anybody that have burchase those 16 GB tablet or phone. Specially if you have pictures and musics that you need to keep. The market carries 64 GB and up so make your best judgment and save.
