The GoPro 4 POV action camera appears in a number of different guises including the Session, Silver edition (with built in LCD screen) and the industry leading 4K capable Black edition. No matter which GoPro you choose you need the best Micro SD card possible. At the end of the day it isn’t all about size, it’s all about speed.
The Hero 4 (including the Session), 3+ and 3 series will accept Micro SD cards up to a 64GB capacity. The new grey Hero camera will accept a card with a capacity up to 32GB.
