A TB of storage isn't that much. I'm a retired international networking consultant. I wrote and taught networking courses that used proprietary hardware and consulted with businesses, large banks, medium governments and agencies. I could tell you more, but I'd have to kill you. BTW - see my post in OT about German ban on MS software.
Life is good.
