I got a 256Gb micro SD card which came with a galaxy S8+ phone promo from Samsung. It records with no problem in the Mavic Pro. 1 battery runs out before storage fills up even 1/8 full. I have 4 batteries, but I tend to offload files before each flight if possible, in case of flyaway or crash. I also switch that card to capture panoramas with the gear 360 camera and then put it in the phone that same day to view buttery smooth unedited footage.
