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.
10Gbps is 12 times slower than the maximum bw of TB5.
You could argue most people wont need that speed, but most people don't need pro phone too.
The MacBook Neo runs an A18 Pro phone chip. It's appears to be all there and somewhat ready to give us something like DeX [1].
