Choose the DS1517+ if you want the stronger Intel CPU, higher RAM ceiling, and built-in NVMe M.2 slots for caching; those are the most practical upgrades for SMB use. The DS1517 is the lower-tier Atom model with less headroom, while both are 5-bay units with expansion support and can be upgraded to 10GbE via add-in card. If you care about performance now or future growth, the DS1517+ is the safer buy.
