I just purchased the new Sony a6700 mirrorless camera and am looking for advice on the best memory card to use with it. The manual says it supports UHS-II SD cards.

From the research I've done so far, it looks like the camera can take advantage of the faster write speeds of UHS-II cards, especially when shooting bursts or 4K video. But those cards are pretty expensive.

Would I be okay going with a high-capacity UHS-I U3 card instead for general photography and occasional video? I don't plan to shoot a ton of continuous bursts or 4K video. I'd rather save some money if the performance difference isn't huge.

Also, any specific UHS-II card recommendations for the a6700 from those who have used them? I see a lot of people recommending the Sony Tough cards. But they are pricey and some reviews mention issues with overheating. The ProGrade Digital UHS-II cards look like a good option too.

What's your take on UHS-I vs UHS-II for the a6700? And any standout memory card models I should consider for reliability and speed? Thanks in advance!
