So our Ad-Hoc environment started growing a bit faster than we had originally anticipated. We knew we would have some disparity between site's content size, so we set our content DB max site limits a bit lower than normal (hey, we have 50 of them, so we thought we'd be safe). The thought was that way we could help balance the sizing by adjusting the max counts on the DB's to reflect the physical size based on content.
It quickly became way to much of a pain to manually collate the size details with the site details based on content DB... So here's a little script I wrote up (ok, modified from my original Site Details script) that pulls all the goodness you could want about a content DB direct from the DB itself... <Insert canned warnings about how MS does not recommend querying the DB directly here>
