Bit of late entry to the topic, but I've just purchased the Hero 2018...anyway here's my experience with some sd cards I've tried.
The SandDisk Extreme Pro card could not be read by my unit and gave error, even after formating on unit or Windows PC, so that card stays in my phone! The card in the middle I'm not sure of it's write speed, but it did work but would cut out after about 15 - 30 mins of recording, and then give an error. Just got the Samsung Evo card, write speed is spose to be 60mb/s, and this has so far worked all OK in both 1440/60 and 1080/60.
