Just a question..
i have read online that class 2/4/6/8/10 mean increasing buffer in ascending order.
How about when a card says class 10 + UHS 1/2/3? as well as an accompanying number like 30/45/60/120/etc... mbps
UHS is relating to video right?
Not to mention sandisk(in this example) names their cards funnily, like sandisk ultra/extreme.
Not to mention my ultra's have 30/40 mbps
