Choose the DS425+ if you want a faster Intel CPU, a higher RAM ceiling, and NVMe M.2 slots for cache or storage; it’s the better SMB pick for multitasking and heavier apps. The DS423 is the simpler, cheaper option, but it has a weaker CPU, lower RAM ceiling, and no M.2; neither model gives you built-in 10GbE, and both are 4-bay units with no expansion to 5+ bays.
