Yea, but you have USB3 high speed, record pro-res directly onto, external storage.

So you can spend $100 on a 1TB external drive (rather than $100 on another 128gb of internal storage) and you're way better off. If you're use case is 4k60 ProRes, this makes WAY more sense than recording locally.

They didn’t say “external storage”, they said “a Mac”. Could be a significant distinction
