Choose the RS815+ if you need more headroom: it has a faster CPU, more RAM capacity, and better overall performance for heavier SMB use. Both are 4-bay units with no native 10GbE or M.2 support, and neither is meant for expansion to a larger bay count; the RS815 is the cheaper, more basic pick if you only need simple file storage.
