The maximum bitrate from my understanding is 78 Mbps which is 9.75 MBps.
10 class micro-SD card mans 10 MBps so it should be perfect!
So why all the websites are recommending much more expensive micro-SD cards with much bigger specs?
Is there anything wrong in my understanding?
Is there anyone using cheap micro-SD card to shoot 4K video here?

@megacliff58211, to consistently achieve the best results with your GoPro camera it is important to select microSD cards that are known to work well with the model you have.
As far as I know, depending on read/write speeds, not all Class 10 microSD cards are capable of handling high resolution videos (e.g. 2.7K, 4K) which can eventually cause the camera to freeze and throw SD errors at some point. For example, a microSD card can have a read speed of 95MB/s and a write speed of 90MB/s while another SD card can have a read speed of 80MB/s but the write speed is only specified as 10MB/s minimum.
We recommend only purchasing name brand SD cards through official resellers. Check this article to see our list of the most up-to-date GoPro recommended microSD cards.
