The simple answer is that one is authorized and warrantied for dash cam use and the other is not.Why, out of curiosity? It's $30 more for a slower U1 card vs U3 for less. What's the upside?
*Fine print on all Samsung Evo Select cards*
"Warranty does not extend to dash cam, CCTV, surveillance camera and other write-intensive uses."

Sandisk High/Max Endurance cards top out at 256GB and are U3 rated.
Western Digital Purple goes higher (512GB and up), but is only U1 rated. This will only be an option if I discover that I need more than 256MB which will be doubtful.
I have not done the math to see if a dash cam would be write limited by a slow U1 card or not, but perhaps someone here can do it. What minimum write speed does a 2K front/1080P rear dual dash cam require? What about 4K front/1080P rear dual one?
