I plan to shoot 4K footage on my Mavic and I'm wondering what I should use in terms of microSDXC... I currently own (2) of these SanDisk Extreme 64gb. I have two questions that maybe you guys can help me out with.... 1) I see there's a newer version of the same card I purchased here - does anyone know the difference? 2) I also see there's and Plus version of the same card here - does anyone know the difference? I obviously want the best since I've shelled out good money on the Mavic...but if none of these make a difference in quality and they're all marketing gimmicks I'll probably stick with what I have. Any advice?
