if the n3ds really supports uhs-3, then the difference wouldn't be 20 sec, it would be even or at least 1/3 time compared to the class 10 card. besides that, the slow one of them wasn't stock fresh, but the uhs3 was. this little time difference of 20 sec on such a big file is nothing. could be even toleranceOnly? 20 secs is an very big boost in speed..
