Hero4 Memory Card

Lexar 633X  Specs: microSDHC/microSDXC UHS-1 card speed rated at a class 10 95MB/s read speed

Although Lexar does not not an exact write speed (from tests around the internet people are getting 40-44 MB/s) for this card just listing it at less than the read speed this card works perfectly when recording 4k with protune on.

Sandisc Extreme Specs: microSDHC/microSDXC UHS-3 60MB/s read & 40MB/s write speeds

This card works great when using a Hero4 shooting in 4k with Protune on.

Yes this may add another $50-$75 to the cost of your GoPro purchase but if you don’t not have a card the complements the performance of the camera those settings are useless.  Some say well I may not be shooting in 4k yes that is understandable.  I don’t either but, every time I have tried out a cheap “discount” cards in any of my GoPro cameras I have had some sort of problem.  Whether it is a corrupted file, incomplete file or just a failure to record and the camera just stops recording.  No one wants this right in the middle of an epic moment on that once in a lifetime cruise or vacation.  Get a GOOD Hero4 memory card!

Bellow are Amazon links to both of these cards.
