Buffalo TeraStation 5420RN 48TB 4-Bay Rackmount NAS Server

The Buffalo TS5420RN4804 is a rackmount network attached storage server built for organizations that need dependable data protection and plenty of room for growth. It arrives with four 12TB hard drives already installed, giving you 48TB of raw capacity that can be arranged in several RAID configurations to balance performance and redundancy.

Maintenance stays simple because each drive sits in a hot-swappable bay, so replacements or upgrades can happen while the system keeps running. A 2.04 GHz Annapurna Labs AL524 processor works alongside 8 GB of DDR4 memory, allowing the unit to handle simultaneous file requests, backups, and media streams without becoming a bottleneck. Dual 1 GbE connections and a 10 GbE port let you place the TeraStation on today’s faster networks and still keep an upgrade path for the future.

For administrators who must meet strict compliance rules, the server offers 256-bit AES encryption and optional two-factor authentication. Built-in hooks for services such as Dropbox and Amazon S3 make it easy to create a hybrid setup that merges on-premises speed with off-site redundancy. The appliance also integrates smoothly with popular virtualization platforms, so it can serve as shared storage for virtual machines or as a reliable backup target.

Whether you manage an office that needs a central file repository, a creative studio handling large media projects, or a remote site requiring secure data replication, this TeraStation gives you the capacity and safeguards to keep work moving.
