Pick the RS818RP+ only if you need redundant power supplies; otherwise the RS818+ is usually the better value. Both use the same CPU class (Intel Atom C2538), have 4 bays and no native M.2 support, and can be expanded with the same 8-bay RX418; neither has built-in 10GbE. The main practical difference is memory headroom: RS818RP+ tops out at 16GB ECC, while RS818+ supports up to 2GB stock unless you’re using a different hardware revision—so verify the exact unit before buying.
