Volume Expansion & Backup

When running out of the hard drive capacity on the Synology DiskStation, the Synology DX513 provides an easy way to immediately scale capacity by an additional 5 hard drives. The RAID volume on the Synology DiskStation can be expanded directly without having to reformat the existing hard drives, ensuring the Synology DiskStation continues its service during the capacity expansion. When created as a separate volume, the Synology DX513 provides a great solution for backing up the Synology DiskStation.

Reliable Plug-n-use Design

The Synology DX513 is connected to the Synology DiskStation using an eSATA cable with custom-designed connectors on both ends, ensuring a reliable connection and maximum throughput. The eSATA 3.0 Gb/sec definition allows the hard drives in the connected Synology DX513 to operate as they are the internal ones of the Synology DiskStation.

Green & Easy to Manage

The HDD hibernation can be manually configured to take effect automatically when the system has been inactive for a period of time. This not only save energy but also extends the lifespan of the hard disk.

Synology DX513 is managed with the DiskStation firmware Synology DSM. No firmware installation is needed.
