Last friday I bought my first real droine, the Mavic Ait Fly More combo.
The day afer I bought a micro Sandisk SD Card 64GB with a& write-speed of 85 MB/s.When I fly my drone, it always says the card to too slow to record 4K.

Is this correct? If so, what speed should I get to shoot 4K?

Did you buy from a reputable manufacturer or some odd-bod selling reputable brand cards. You can buy cards that the manufacturer rejected on quality grounds very cheaply and pass them off as the quality card?????

DJI say these are the supported cards

Problem is, micro/SD card Manufacture's marketing / sales are playing fast & loose with read speeds, often implying write speeds are similar.  Along with picking data transfer sizes that give highest possible read speed (and sometimes write) speed.

I particular hate the 10x, 20x, 100x, ect. non-sense that is put on face of shell that micro/SD cards come in.

That's the strange thing... I can record in 4K witrh the card and when I look at the video, I see no issues...

Maybe it's not a real Sandisk card? Beware: Amazon Still Sells Counterfeit Memory Cards

Btw, I just LOVE my Mavic Air...
