What works well for me is a nuc10 i3 with 2T m.2 for system snd recordings and external usb-3 for movies.
It has thunderbolt, but I don't see any reasons to go 40G/s on a sata disk limited to 500 M/s.

Somebody, sorry to forget who, maybe JohnP, set me a link to a dance clip. I was having smoothness issues. Turns out that they were broadcast artifacts and play back is as smooth as you could want. (The so-you-can-dance clip was as extreme an example as you could hope to find) (but all this is 1080)
