I use MongoDB as my main database in my business. I really do not like SQL, MongoDB is easy to use. It is amazingly small. Our main server is an atom-based 4"x3"x1" box with a 16gb ssd and an external 2TB USB drive. It has 1gb of memory. Mongodb is so efficient that we've seen no need to get a bigger server, even though several other functions are on that system too.
