The old iPhone 17 Pro has USB 3.2 Gen 2, which is good for 10Gb/s.
You can already record 4K60 ProRes to an external SSD. This feature already existed for a year, so I assume you didn't actually need it?

I think you're looking for a MacBook Pro the size of an iPhone.

You could argue most people wont need that speed, but most people don't need pro phone too.
Can you show me the workflow which uses this and has an iPhone as the bottleneck
Can already do iMessage over satellite. Most “data” is download and I predict some satellite service that sends basic broadcasts (traffic, news, Text-to-speech podcasts) squeezed into a few mbps by pointing your phone at the sky (or a small cabled antenna for around the clock use). Would love to go carrier-less.
My iphone 16 pro max can do 4K ProRes HDR or Log at 120 FPS when plugged into a SSD. If I had more builtin storage I could do it without the SSD. If you don't mind more dongling you can also have an external display along with the external SSD.
I actually do this because it's the behavior I've wanted for years, and I care about it enough to go through the relentless annoyance.
