My MA complains that my SD card is nt fast enough for 4K video. WHat class of card do I need? AQlso, does anyone know how much data per minute is generated in 4K video? Trying to work out what size of card to get.
Thanks.

Sandisk Extreme Pro micro SD card is what I use with no issues whatsoever Google Search Link

^^^ What he said. SanDisk Extreme has worked well for me.

Sandisk Extreme as they've both said are pretty reliable. 64GB cards seem to be the sweet spot in quality and cost to storage capacity ratio.

I bought 2 cards and reliased after that it would not do 4K... So back to the shop and look for Sandisk that has 4K on the packet. As a normal photographer for many years I prefer to use a couple of cards rather than one big one... Just in case one fails... And I have had it happen.. for a weding of course !!

I would agree with all above, Sandisk extreme cards will cover your needs and are easily available at reasonable price. Although you shouldn't need the 'Pro' version, but they might be a bit faster in transferring data to your computer if that's important to you, but are twice the price of the non pro version of the extreme.

I got same trouble
i bought sandesk extreme 64
it works properly with me

Hi there, sorry to hear that. Kindly check the list below for compatible SD cards for your Mavic Air. I hope this will help.

This one worked a treat: Amazon SanDisk Extreme 64GB

Cost me £23.49.  I think I did find it slightly cheaper elsewhere (maybe £2-£3) but I wanted it "tomorrow"

Thanks everyone, ended up getting the Extreme Pro 64GB.
