Hmm... I wonder if you would have gotten the same capacity increase with just a 3TB drive. And since you've filled all of the slots, next time you'll need to replace one of the existing 3TB drives and won't get as much of a boost (maybe 1 TB as it finally uses the part of the 4TB reserved for expansion).

I did some experiements before with the Capacity Calculator which basically informed me it was better to buy a single larger drive now, else have buy multiple drives at the same time later to get an increase in capacity.

 

I've added some screen shots to the end of the blog entry that show if I'd filled the Drobo with five 3TB drives, I'd have to replace three of them before I would get additional storage.
