Choose the DS1515+ if you want materially better performance: it uses a much faster Intel C2538 CPU and supports a higher RAM ceiling than the DS1515’s Annapurna Labs chip. Both are 5-bay units with the same 2× eSATA expansion support, and neither has built-in 10GbE or M.2; between them, the + model is the decisive pick for SMB use.
