Synology DiskStation DS1517+

High performance NAS optimized for encryption and intensive tasks

Centralized storage solution with outstanding performance

Synology DiskStation DS1517+ is a 5-bay NAS powered by a quad-core CPU with AES-NI hardware encryption engine. Coming with quad 1GbE LAN ports, it can be installed with a 10GbE network interface card (NIC) or a dual M.2 SSD adapter card, thereby enhancing network speeds or boosting performance with SSD cache.

Supercharge your storage with speedy performance

Equipped with dual-channel memory and a PCIe slot, DS1517+ supports installing the dual M.2 SSD adapter card, M2D17, or the 10GbE NIC, for high-IOPS system cache and ultra-fast data transmission respectively.
