A:Answer A micro SD card is what you need. Learn from my mistakes though, I own a GoPro 4 black edition. If you plan to record at 2.7k or 4k, you HAVE TO HAVE the Sandisk Extreme PRO edition!!!! it is the only SD card that can keep up with those high speeds and not drop frames because of the lack of speed! The Pro will record up to 95mbs while this card only does 60mbs. You NEED the Pro, its worth the extra few dollars! I made this mistake, I hope it helps!
