I would wager that the system being used here only has enough space to
house 3 drives, thus the question, which means that adding a fourth
drive probably requires buying a whole new server.  Nowadays the drives
themselves are rarely the limiting factor on how many people use, since
you can get a stack of them for under $100 each.  Instead the limit for
small servers is always based on the physical enclosure and then
potentially the number of available drive ports.
