Regarding sd card for slot 1

Sorry if this has been asked a thousand times before. I did a quick search here and didn’t specifically find any straightforward answer to following question. I’m currently waiting to get my R36S delivered to me but meanwhile I’ve been understanding that sd card swapping is a must. So for slot 2 I got that covered. But for slot 1 I haven’t bought a card yet. The question is, will a regular card like a Kodak 32GB suffice? Do I have to think about the class/speed and such? And do I need more than 32 or will that suffice?
