    Is the P3 pro camera compatible with SDXC? My understanding is that XC U3 is recommended for 4k video.

    The camera is SDXC, but does not appear to offer U1 or U3. Even if it did, the DJI camera firmware has a bug (feature?) that locks the SD bus at "Normal Speed", which is 12.5MB/s.

    Normal speed, 12.5MB/s is plenty fast enough for 4K and UHD video (60mbps encoding rate = 7.5MB/s), but really sucks when taking multiple (rapid shot or AEB in J+R) pictures and the camera locks up for 20-30 seconds while it writes the data to the SD card.
