Synology RX418 4-Bay Expansion Unit

The Synology RX418 is a rackmount expansion unit that adds four drive bays to a compatible Synology RackStation without forcing you to replace any existing hardware. A single eSATA cable, which comes in the box, links the chassis to your NAS so the extra capacity appears instantly inside DiskStation Manager.

The enclosure accepts both 3.5 inch and 2.5 inch SATA hard drives or solid-state drives. Each bay is hot swappable, allowing you to replace or upgrade a disk while the server stays online and your users keep working.

Offices that outgrow shared folders, creative studios archiving large media files, or home labs storing surveillance footage can all benefit from this expansion. The 12 inch depth fits standard and wall-mount racks, the integrated 100 watt power supply is ready for worldwide voltages, and drive hibernation cuts energy use when disks are idle. At 25.1 dBA, the unit keeps noise low so it will not dominate a small server room.

Management stays simple because everything runs through Synology DSM. You create volumes, set up RAID protection, and schedule snapshots with the same interface you already know. The package includes the expansion chassis, eSATA cable, AC power cord, and an accessory pack, so installation can begin as soon as you open the box.
