Hello,

I have got a 64gb sandisk microSD. It states a maximum of 30mbps, but my GoPro hero 4 Silver records at 45mbp/s 1080p60 with Protune (if i remember correctly). I have recorded many different videos and have not noticed any problems but am soon going on a ski trip. What are the consequences of doing this?

Thanks, Vee
 
Solution
Your card is likely 30MB/s, while the stream is probably 45Mb/s. Zero issue with speed.

If you were using too high a speed for the card, it would probably stop recording after about 20 seconds and say something like 'buffer full'.
