iPhone 16 Pro Max 4k 120hz size

Does anyone happen to know the average time that each minute of 4k 120hz video should be? Also, would I have to attach an external drive to the iPhone, or is that just if I am recording in ProRes?
thanks!

At minimum. 1 gig per minute. You don’t have to attach external storage
