Can you record 4k ProRes 4444 on the Inspire 2 using microSD, or do you need the big CineSSD units?

I had assumed I'd need the expensive CineSSDs for shooting ProRes 4444 with the Inspire 2, but a friend just told me that he normally shoots to microSD. Can anybody corroborate that? Details are scarce online that I've been able to find. via /r/drones https://ift.tt/2ZwZAI7
