Storage expansion without downtime
Easily add five additional drive bays to your Synology DiskStation. The DX525 supports both 2.5" and 3.5" SATA drives and features plug-and-play setup and hot-swap capability for uninterrupted operation during capacity expansion.
Online volume expansion
Managed through the host NAS's DiskStation Manager (DSM), the DX525's additional bays are immediately available upon connection. On-the-fly volume expansion ensures uninterrupted service and storage expansion on the host.
Dedicated local backup solution
The Synology DX525 provides a dedicated local backup solution for your Synology DiskStation. When configured as a separate volume, it safeguards data on its local disks in case of system failure.
