This solution costs only one extra disk (which is quite cheap nowadays)
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.
