Recommended micro SD cards for Mavic 2 Pro & Zoom

Recommended Posts

On official DJI website we can find a very short list of recommended microSDHC / microSDXC cards for Mavic 2 Pro / Zoom. Just a few models by two manufacturers:

List of cards which were successfully tested and worked fine with Mavic 2 Pro / Zoom:

In fact you can use any other microSDHC or microSDXC card which meets all of these requirements:

  1. UHS bus:
    UHS-I or higher.

  2. UHS Speed Class:
    U3 or higher.

Some cards may be also marked with V* and A* class icons. They are optional if previous requirements are met, but if their icons are present on card, they should be not lower than:

  1. Video Speed Class:
    V30 or higher.
    Icon: Video Speed Class 30.png
  2. Application Performance Class:
    A1 or higher.

There are a lot of good 256 GB micro SD cards on the market, but the owner's manual for the Mavic 2 Pro and Zoom states that "Supporting Micro SD with capacity up to 128 GB and R/W speed up to UHS-I Speed Grade 3."

I know that sometimes cameras / drones manufacturers say their hardware will only support up to a certain size of micro SD card, but in fact they actually support larger micro SD cards.
Have you tested a 256 GB micro SD cards in the Mavic 2 Pro and Zoom, it works?

I haven't tested it by myself yet, but i saw a comment where Mavic 2 Pro user confirmed what 256 GB micro SDXC card worked fine in his drone.

Here is the quote:

After inserting the microSD card into the Mavic 2's microSD card slot and connecting turning on the Mavic 2, RC and DJI GO 4 app, you should see in the DJI GO 4 app camera settings an option to format the SD card then select the "Storage location". I didn't saw any warning about storage space, or low speed. The 256GB microSD card works as expected.

The exFAT formatted microSD storage is 253.3GB.

Don't get confused by the microSD cards speed class. UHS-II cards are backward compatible by falling back to the lower speed interface UHS-I (which is the native interface of the Mavic 2).

I picked this microSD card because it has a wider temperature operation range compated to the Mavic 2. If something goes wrong (temperature wise) then I still get all the data - if I can find my Mavic 2.

I did some performance tests with the internal memory and the microSD card mentioned above.
I inserted the microSD card into the Mavic 2 Pro microSD card slot and connected the Mavic 2 Pro to my Mac Pro via USB 3 cable.
As benchmark software, I used DiskMark v2.1 (Apple Store).

If it wouldn't be necessary to run this test with a battery packed and powered on Mavic 2, then I would spend more time testing the internal and external memory.
