I need a memory card for my Mavic Air.
Here I have a Samsung Evo XC 1, UHS-1
This one here:

Is this enough or should I use one of the supported memory cards?

Try it and see

Since this is my first drone, it will be difficult to see from the recordings poob this memory card delivers perfect write rates.
It would be good if someone knew so that I don't have to deal with it. :-)

Mavic Mini supports SD cards specs of UHS-I Speed Class 3 or above. You may test out your SD card and check if the files on the SD card are playing normally and smoonthly.

It is a Mavic Air.
Don't want to try it out beforehand.
Would rather buy a better card straight away if the available card is not sufficient.

I say, would you fly with this card or take another one?

I've have had a similar card. I never had any issue but I was getting the SLOW CARD message when filming in 4K. I had a opportunity to change for a faster one, so I took it.

Choose wisely
