Sounds like a lot of data. I know of videos.trom.tf "A trade-free video hosting platform for science/technology/nature videos in the English language. You do not have to trade your currency, data, attention, freedom or anything else, in order to use it."
They 'host' a huge collection of science documentaries and other 'enduser' level videos, but may not be interested in research level storage if it's terabyte upon terabyte ? He could ask them, and perhaps get a suggestions for other science hosters that have a larger backend ? Maybe they are seeking out each other in a network.. Worth trying I think..
