Your workflow sounds real heavy-duty!

In my case I record-livestream conferences (local and international) - and yes, I have forgotten to hit the vMix record button in a couple of instances where I had some explaining to do! Luckily it was my regular client who loves me and is willing to forget the rare lapse if I grovel hard enough! No $3m jobs in my case but irritated clients are no fun to deal with!! I'm a one-man show operating 3 cameras, panning-zooming, video mixing, PowerPoint capture, etc. Thankfully the audio is often done by someone else and all I do is capture it via XLR into my cam direct.

I generally have the second laptop running anyway (to self-monitor my webcast) so having it also record won't be an issue. But its comforting to hear of your storage solution using 2 cards totaling 512GB

I am going to try the laptop solution first (cheaper :-) and then graduate to the Atomos if I feel the need.

Thanks for all the great info you have given me and for a very useful discussion.
