4-bay 1U rackmount expansion unit for 1U RackStation
Access Synology solutions in a cost-effective and environmentally responsible way. All certified refurbished products are put through extensive testing, comply with stringent quality standards, and come with a 2-year warranty.
When the storage capacity on Synology 1U RackStation reaches its limit, Synology expansion unit RX418 provides easy capacity expansion by adding 4 3.5"/2.5" SATA drives to the system. Synology RX418 can also be used as a dedicated local backup destination of Synology 1U RackStation for comprehensive data protection.
Simply connect Synology RX418 to corresponding Synology RackStation and it is ready to use. Drives in the connected Synology RX418 operate as though they were internal to the connected Synology NAS and can be managed directly by Synology DiskStation Manager (DSM), with no additional software installation required.
Award-winning Synology DSM provides an intuitive user interface for easy system management. Drive hibernation can be configured in DSM 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 the installed drives.
Leverage high sustained performance and reliability with enterprise-grade drives with built-in data protection designed for Synology systems.
