Compatibility list for this model: https://www.synology.com/en-us/compatibility?search_by=products&model=RX418 Function
When the storage capacity of Synology 1U RackStation is reached, the Synology RX418 offers easy capacity expansion by adding 4 3.5 “/ 2.5” SATA drives to the system. The RX418 can also be used as a dedicated local backup destination for Synology 1U RackStation for comprehensive data protection. Just connect the Synology RX418 to the corresponding Synology RackStation and you can start using everything. Disks connected via RX418 work as if they were internal disks of Synology NAS and can be managed by Synology DiskStation Manager (DSM) without the need to install additional software. The award-winning Synology DSM operating system offers an intuitive user interface for system management. Disk Sleep can be configured on the DSM to automatically activate after a period of system inactivity. This not only saves energy, it also extends the life of the installed disks.
