What is the reason for the two SD card slots on CS

 

[With The Birds]

The reason, presumably, is that DJI envisioned that users of the device may like to add additional storage/access SD cards.

Transfer footage from one SD card to another.
Transfer footage, cache, logs, or other files to/from internal storage.
