Probably better just invest in the best one since we now have 4k recording capability
im gonna go with the 32 gb samsung evo![]()
Well Samsung has some pretty fast Class 10 UHS-1 cards they just came out with, so they aren't on sale (essentially just MSRP for now), but I believe... Toshiba? has a UHS-2 card in the pipeline which isn't available yet.
Really, the read speeds should be sufficient on current cards, but depending on what you are doing, the write speeds can slow you down. Mainly video recording, as you said.
EDIT: Here's a link to Samsung's card. Up to 90MB/s read/80MB/s write
is it better to store everything on the microsd card instead on the phone? makes it run faster?
FYI. This card will not work in a Galaxy S5 because it is NOT a micro sd card.
