Pick the RS2418+ if you want the cheaper, lighter box: it has the Intel Atom C3538, 4GB RAM with a 64GB max, 8 bays, no built-in 10GbE, and no M.2 slots. Choose the RS2421RP+ if you want more headroom and redundancy: it uses the AMD Ryzen V1500B, supports up to 32GB RAM, still has 8 bays but adds a redundant PSU (“RP”), and also has no built-in 10GbE or M.2.
