Have purchased the card through another dealer. My old Mini-SD was too slow for my GoPro 4 Black. This writes the 4K mode ProTUNE beyond good and evil, so they want to have a map to the side that can hold all the data.
The San Disk Extreme Plus is perfectly suitable to the 32 GB card fit 1 hour and 7 minutes 4K material in ProTUNE mode at 30fps. So if you want get the most out of his camera out, is hereby operated correctly !!!!
