Pick the DS120J if you want a newer 2-bay unit with a faster CPU and better upgrade headroom: it has 512 MB RAM versus 256 MB on the DS119j, and one extra bay for RAID/expansion flexibility. Neither model has 10GbE or M.2, so those aren’t deciding factors here. The DS119j is only worth it if you’re getting it significantly cheaper and can live with a single bay and lower RAM ceiling.
