Can I Use 128GB in GoPro?

Yes, at least in the newer models. You can use 128GB microSD cards in these models:

• HERO6 Black
• HERO5 Black
• HERO5 Session
• HERO Session
• HERO4 Black
• HERO4 Silver
• HERO4 Session

Sequential Write Speed

Not all 128GB cards are fast enough for the high-end video modes of these GoPros. Specifically, you want ones that have fast sequential write speeds. I’ve put together some recommendations for specific models:

• HERO6 Black
• HERO5 Black and HERO5 Session
• HERO4 Black and HERO4 Silver

microSDHC vs microSDXC

The 128GB cards you see will all be microSDXC. Only cards 32GB and smaller will have the microSDHC label. You won’t find any 128GB cards sold with microSDHC labeling.

The difference between them is in the filesystem formatting used. microSDHC cards use FAT32 filesystem. microSDXC cards us a newer and more flexible exFAT filesystem.
