It depends on the structure of the DB - 6.5GB is large if its attributes, if its documents then not so much. If its an index of documents then a different problem. Access patterns matter to. Like if its a 6.5 GB database that stores OLTP data, then yes thats large. If its a history of document modifications then probably small. If its historical data for a data cube sort of app, then its pretty small, I'd say tiny - I've worked on ones that get into the TB's.
