The Synology DX517 is a 5-bay SATA expansion unit designed to increase storage capacity for specific Synology NAS systems. This external expansion unit connects directly to your existing NAS to provide additional drive bays without requiring a complete system upgrade.

Key features include:

• 5 x SATA drive bays for additional storage expansion
• Compatible with DS1517+, DS1817+, DS1019+, DS1517, DS1817, and NVR1218 models
• External expansion unit design
• Direct connection to compatible Synology NAS systems

This expansion unit is ideal for businesses and power users who need to scale their storage capacity as their data requirements grow. It's particularly useful for video surveillance setups, media servers, and backup solutions where storage needs frequently exceed initial capacity planning.

The DX517 offers a cost-effective way to expand your existing Synology NAS investment rather than purchasing an entirely new system with more bays.
