Buffalo TeraStation 5420RN 16TB 4-Bay Windows IoT NAS Server (4 x 4TB)

The Buffalo WS5420RN16S9 is a network attached storage server that offers four drive bays and sixteen terabytes of factory installed capacity. Running Windows Server IoT 2019, it integrates with existing Windows tools and services as soon as it joins the network. Buffalo includes four 4 TB NAS grade hard drives that are preconfigured in RAID 5, so essential data protection is ready without extra setup.

Businesses that rely on Active Directory, Microsoft 365, or Azure will find the appliance familiar to manage. File shares, permissions, and cloud syncing can be handled through the same Windows consoles already in use, and because Client Access Licenses are not required, adding users or devices does not increase licensing costs.

Inside the chassis an Intel Atom C3338 processor works with 8 GB of ECC DDR4 memory to keep file serving and backup tasks responsive. A 10 Gigabit Ethernet port accelerates large transfers, which is helpful for creative teams moving high resolution video, engineering departments archiving project data, or IT administrators running nightly backups within a limited maintenance window. Two additional Gigabit ports support link aggregation or network separation when needed.

The TeraStation can operate as a primary file server, a virtualization storage target, or a reliable destination for backup and disaster recovery. Hot swap drive bays allow maintenance without shutting down user access, and the unit supports optional RAID 6, RAID 10, or JBOD configurations to match changing resilience requirements. Buffalo backs the system with a three year warranty and round the clock North America based technical support, giving administrators confidence that help is available whenever it is needed.
