My NAS boxes each have 16GB. One has two 4TB and two 3TB drives in mirrored pairs; the other has three 1.5TB drives in a RAIDZ1 setup. And that's just for being a NAS. I would probably need more RAM, especially on the one with four drives, if I were also running applications on them. Why two smaller boxes rather than one big one? Mostly because I already own a pair of low end AMD systems using mini-ITX motherboards and AM1 socket CPUs that I originally got for another purpose but was no longer using, and I already had all the drives. Those motherboards only have two DDR3 memory sockets and thus have a RAM ceiling of 16GB, and the cases will only hold four hard drives.
