Maintain dependable shared storage in a space-efficient 1U chassis designed for rack environments where every unit matters. The Buffalo TeraStation 3430RN delivers 4 TB of installed capacity with two 2 TB drives included, plus two open bays for future expansion. That gives IT teams a practical path to grow storage without replacing the platform. Built around 2.5 GbE networking, this NAS is suited for faster file access than legacy Gigabit-only systems, while RAID support helps preserve availability when a drive fails. iSCSI support adds flexibility for teams that need block storage alongside traditional file sharing. For surveillance, branch office, and departmental storage, the 3430RN fits neatly into a controlled rack footprint and keeps data accessible to multiple users and systems. This model is a strong fit when you need more than basic consumer NAS behavior. It is intended for environments that value rack-mount integration, expansion headroom, and storage features that align with business continuity. The result is a compact NAS that supports day-to-day collaboration while leaving room for future capacity planning.
