Why using external SSD with iPhone 15 Pro?

There is this thing I don't understand, when trying to film video in Log ProRes at 4k 60fps, on iPhone 15 Pro, why do you need an external SSD?

For instant if you have the 1TB iPhone15 Pro, do you still need an external SSD?

Is the writing speed on external SSD via USB-C faster then the speed of writing on the internal 1TB memory of the iPhone?

Where you get this from is not clear to me. Do you get any such warning on your iPhone?

This is Apple Article that may help you.

ProRes support for 256 GB, 512 GB and 1 TB storage capacity:

4K at 60 frames per second (fps), iPhone 15 Pro and iPhone 15 Pro Max only, when using an external storage device that supports speeds of at least 220MB per second and maximum power draw of 4.5W.
4K at 30 fps, 25 fps and 24 fps.

Well this is why I'm intrigued, as per your article, it looks like the speed of writing a video file on an external SSD via USB-C port is higher than the speed of writing to the iphone internal memory ... right?
