6-8TBs is one big library!
The reviewers at Newegg and Amazon don't seem to think the Drobo is TOO loud, however the new unit seems to be quieter AND runs cooler.
In your case, you may have to wait awhile for 1.5TB drives to become more affordable and even more reliable. That would give you a little more that 4TBs on a Drobo, but you may need to of them dark, shiny babies.
