Choose the DS1621+ if you want the stronger platform: it has the better CPU, supports up to 32 GB RAM, has 6 bays instead of 5, and expands farther; it also offers 10GbE expansion but no built-in 10GbE, and it uses M.2 slots for SSD cache. Choose the DS1522+ if you want the newer, simpler 5-bay unit with built-in 2.5GbE and M.2 cache slots, but it has a weaker CPU and a lower RAM ceiling than the DS1621+.
