Back in the late 90s when I worked on a Well Known Soap, we built the first integrated Production/Post Production System in this country, possibly the world!
And we had a rack full of Seagate 50Gb drives, each of 'em about the size of a modern desktop computer giving us an unheard of 1Tb! That was £tens of thousands without the aircon and other racks of switching stuff to communicate with the stages, edit suites and sound dubbing suites.
