Buffalo TeraStation 5420RN 32TB 4-Bay Rackmount NAS Server

The Buffalo TS5420RN3204 is a four-bay rackmount NAS that brings 32TB of dependable, centrally managed storage to offices, creative studios, and branch locations that need fast, secure access to large files. Four hot-swappable 8TB drives sit behind a RAID engine that supports levels 0, 1, 5, 6, 10, and JBOD, so you can tune the balance between performance and redundancy to match your workflow.

A quad-core Annapurna Labs AL524 processor running at 2.04 GHz teams up with 8 GB of DDR4 memory to keep file transfers smooth, even when multiple users connect at once. Two gigabit Ethernet ports handle everyday traffic, while a dedicated 10 GbE port is ready for bandwidth-intensive tasks like CAD projects, 4K media, or rapid virtual-machine backups. External drives, UPS units, or card readers can plug into the two USB 3.2 and two USB 2.0 ports for quick offloads and additional backup options.

Data protection is built in at every layer. Hardware-based 256-bit encryption guards files at rest, two-factor authentication prevents unauthorized logins, and snapshot backup lets you roll back to an earlier point in time if ransomware or accidental deletes strike. Integration with leading cloud services gives you another destination for off-site copies, adding an extra layer of business continuity without extra hardware.

Because the chassis uses a 1U form factor, it slips easily into standard server racks, making it a natural fit for cramped equipment rooms or colocation cabinets. Hot-swap support keeps downtime to a minimum; you can replace a failed drive without powering the system down. For IT administrators who want storage that just works and keeps data safe, the TeraStation 5420RN delivers reliability and flexibility in equal measure.
