Instant Volume Expansion & Backup
Synology DX517 provides an easy way to scale up to 5 additional hard drives on-the-fly. The RAID volume on the host Synology DiskStation can be expanded directly without having to reformat the existing hard drives, which ensures seamless capacity expansion without service downtime.
Synology DX517 can also be used as a dedicated local backup destination for Synology DiskStation. When created as a separate volume, DX517 provides a great backup solution to its local hard disks in case of system failure.
Reliable Plug-n-Use Design
Synology DX517 is connected to Synology DiskStation by an expansion cable with custom-designed connectors on both ends. The convenient hot-swappable drive tray design ensures simple and quick hard drive installation and recovery in the event of failure or when additional drives are to be installed.
Green and Easy to Manage
Deep Sleep can be manually configured to take effect automatically when the system has been inactive for a period of time. This not only saves energy but also extends the lifespan of hard drives. DX517 will also power on/off automatically along with the attached DiskStation without handling. The operation of the DX517 is entirely integrated with DSM on the host DiskStation. This design allows full control of the whole system with your browser only.
5-bay 3.5"/2.5" SATA expansion
Easily add 5 additional drive bays to Synology DiskStation1. Supporting both 2.5" and 3.5" SATA drives, DX517 is a flexible solution supporting on-the-fly volume expansion or serving as a local backup destination.
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 ensures 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 easy drive installation and replacement without powering down the system. Screwless drive tray design reduces the time needed for system setup.
Dedicated local backup solution
Synology DX517 can be used as a dedicated local backup solution for the Synology DiskStation. When created as a separate volume, the DX517 provides a great backup solution to its local hard disks in case of system failure.
