A:AnswerThe answer that the Geek squad gave you about the 3 in the "U Shape" meaning that it is Class 3 is incorrect. The speed ratings for SD memory cards are defined by the SD Association. As time has passed, they have come up with various speed ratings. The Speed Class ratings are Class 2, 4, 6, and 10. This card is a Class 10 which is the fastest class rating. The UHS Speed Class ratings are U1 and U3. This card is a U3, which again is the fastest rating.
A:AnswerYes you can. But the video quality won't be in HD I think and assume. If the tab 3 doesn't do HD playback then you will view it in regular video quality but the SD card is worth it. It has fast upload and download speed performance
