That's a third of what a free personal Google account would get. I think emails alone would equal that for many faculty/staff, especially if you "archive" everything and only delete spam. I agree that there will be a lot of people who minimally use the services, but email would likely be the highest space waster. Tons of people across the domain getting the same HTML-heavy newsletters, transactional emails, etc, would add up to a lot. Plain text emails are rare these days.
