@killyourfm indeed. if you want to edit straight from the NAS, i would recommend one with 10Gbit network port, and make sure devices connected to it do so using 10Gbit networking too. That way there's little chance you'll have any issues with it, it might even be faster than editing locally (although latency could be higher).
The tricky part is finding a good tradeoff of which RAID type to use, and the answer depends on how much you value performance vs security, and which NAS and filesystem.
