Pick the DS509+ if you want the stronger box: it has a faster CPU and a higher RAM ceiling, while the DS508 is the older, weaker option. Both are 5-bay units with no expansion, and neither has built-in 10GbE or M.2 support. For a home/SMB buyer, the DS509+ is the safer choice unless you’re only buying on price and basic storage needs.
