Properties all SD cards have (should):
Waterproof (but you should not take a chance on it)
Shock resistance (at least if the card is not more than about 3 m height onto a hard floor falls)
Write Protect (plastic tab on the side)
-> In my view, particularly fast cards only makes sense if you want to use in video cameras (Full HD), since this heat is not so strong (in my experience) and thus also last longer. So if you do not want to record for hours at a time, so it can still as this resort to a standard card here, thus neatly save money.
