Choose the DS212+ if you want the faster CPU and more headroom: it has the better processor, supports up to 512 MB RAM, and is the stronger pick for heavier SMB use. Both are 2-bay units with no expansion, no 10GbE, and no M.2, so the real decision is performance versus budget; the DS212J is the lighter home option.
