Ready-to-use 64 TB NAS

The Buffalo TeraStation 5420 arrives with four 16 TB NAS-grade drives installed and RAID pre-configured. A quad-core Annapurna Labs Alpine AL524 processor at 2.04 GHz and 8 GB DDR4 memory handle file serving, backup and virtualization workloads for small businesses.

Native 10 GbE uplink

A single 10 GbE RJ-45 port connects directly to a 10 GbE switch or workstation without extra cabling, while two additional 1 GbE ports handle standard LAN traffic. This port mix decides whether the unit fits a high-speed backbone or a conventional gigabit network.

Cloud sync and remote console

Built-in support for Amazon S3, Dropbox, Microsoft Azure and OneDrive lets the NAS push or pull cloud backups without a host PC. The Remote Management System aggregates multiple TeraStations into one browser console, and VMware plus Windows Server 2022 certification covers virtualized deployments.
