No, your tablet isn't capable of extracting anything near those speeds from the card. You'll likely see between 7MB/s and 16MB/s writes with between 14MB/s and 20MB/s reads. If there is a significant cost difference go with the more economical card. My advice would be to make sure its NOT a Sandisk Ultra card (just choose another brand, trust us on that, Sandisk Ultra cards in Samsung devices are hit or miss, much more so than other brands) and make sure it IS a class 10 card.
