Online Volume Expansion
Managed from DiskStation Manager on the host NAS, the additional bays in the DX517 are immediately ready to be used once connected. On-the-fly volume expansion helps ensure that storage and services on the host are not interrupted during volume expansion.
Hot-Swappable Drive Tray Design
The hot-swappable drive trays of DX517 allow drive installation and replacement without powering down the system. A screwless drive tray design also helps reduce the time needed for system setup.
Dedicated Local Backup Solution
Synology's DX517 can be used as a dedicated local backup solution for the Synology DiskStation DS1817+ or DS1517+. When created as a separate volume, the DX517 provides a great backup solution to its local hard disks in case of system failure.
