TeraStation WS5420RN 2025 16TB NAS

The Buffalo TeraStation WS5420RN 2025 delivers 16TB of storage across four drive bays in a rackmount form factor. It suits small offices needing centralised file access and backup. The unit ships new and ready for deployment.

16TB capacity and four-bay headroom

Sixteen terabytes provide ample room for shared documents, media libraries and scheduled backups. Four bays allow the installed drives to work together for redundancy or expanded volume space. Heavy database workloads or large video archives may eventually exceed the available raw capacity.

Rail kit and setup media included

A rail kit with mounting brackets and screws enables secure installation in a standard rack. The supplied setup media on an SD card and a quick setup guide walk through initial configuration. An AC cable and a 6a Ethernet cable complete the physical connections.
