Save images - very slow performance

[Alphaquad]

I currently have a Mini 3Pro in use (before the Air2s).

What really bothers me is the slow performance when saving the images.

I shoot 1 picture or a 3 series and it always takes a few seconds until the save is finished and the drone is free again (the image display of the camera).

I use the following cards for my normal DSLRS (Nikon Z) and the drone:

SanDisk Extreme 128GB microSDXC 160MB/s, Class 10, UHS-I, U3, V30

Performance is great on the Nikon but the drone takes a long time to buffer.

Is this normal or is it the card?

What are your experiences?

Thanks.
