Choose the DS420+ if you want noticeably more performance and headroom: it has a faster Intel CPU, 2 GB RAM with a much higher upgrade ceiling, and supports M.2 NVMe cache; it also has the same 4 bays but no 10GbE or expansion. Choose the DS420j only if you need the cheapest basic file backup/NAS box: it uses a much weaker ARM CPU, lower fixed RAM, and lacks M.2 cache and 10GbE, with no bay expansion on either model.
