Yeah I wondered what happened to your HP stream
That'd be a way for sure.
When it comes to storage...it depends on your usage case. If you're going to use the camera in the traditional astro image fashion, an image every couple of minutes doesn't tax USB 2.0. It's only if you get down to an image every second or faster that it becomes an issue. FWIW, I do my planetary imaging on a similarly low-spec USB 2.0-only machine at high frame rates and it gets results.
