Synology Inc. today launched the Synology DX510, an expansion unit to increase the capacity of Synology DS1010+ and DS710+ on the fly. When the Synology DS1010+ or DS710+ is running out of capacity, the Synology DX510 scales up its capacity by an additional 5 hard drives immediately. 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 DX510 provides a great solution for backing up the Synology DiskStation. The Synology DX510 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 DX510 to operate as they are the internal ones of the Synology DiskStation. Availability The Synology DX510 is now shipping globally.
