Sure, but are you really doing all video editing on all projects on the go?

When it's your job job dealing with huge data it quickly becomes very time consuming and error prone to deal with multiple external storage devices. (edit: by error prone I mean human error eg where did I put this stuff?)

8k raw video is very large - even a single project will fill that up and need extra storage to add externally.

A couple 4k cameras filming at 60fps at, for example, tech conference and you can about fit a single days footage on those 24TB,

If you're on location filming a nature show, yes. It's less to upload.
