Pick the RS3618xs if you want the newer platform: it uses a faster CPU, supports more RAM, and includes better native 10GbE options; the RS3617xs is older and generally weaker on performance and memory ceiling. Bay count and expansion are effectively the same class, and neither model has built-in M.2 NVMe slots.
