The 1U Rackstation 4-Bay Expansion Unit from Synology delivers a volume expansion and data backup solution for 1U RackStation servers, by providing an additional four drive slots. With its short depth chassis design, it helps ensure easy installation and deployment in 2-post racks and wall mount racks. It serves as a dedicated local backup solution for a RackStation.

Volume Expansion and Backup: When drive capacity is running low on a 1U RackStation, it provides a solution to immediately scale capacity by providing an additional four slots. A RAID volume on the RackStation can be expanded directly without having to reformat the existing drives, ensuring the RackStation continues providing services during capacity expansion. It also serves as a dedicated local backup solution for a RackStation. When created as a separate volume, it provides a backup solution for local drives in case of system failure.

Reliable Plug-and-Use and Short-Depth Chassis Design: RX415 securely connects to Synology's 1U RackStation servers with a specially designed eSATA cable, ensuring easy connection and maximum data throughput. With its exceptional 12-inches short-depth chassis design, it can be deployed in both industrial standard environments and smaller server rooms with limited space. Optional Synology Rail Kits are also available for easy system maintenance.

Green and Easy to Manage: Deep Sleep can be manually configured to start 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. This also will smartly power on/off with the attached RackStation, so no user intervention is needed to keep this system running smartly and efficiently.
