Move backup and shared data onto a rack-mounted NAS designed for performance-conscious IT teams. The Buffalo TeraStation 5420RN delivers 16 TB of installed capacity in a 1U chassis, giving you a compact platform for file services, backup repositories, and iSCSI-based workloads. With 10 GbE connectivity, it is positioned for environments where standard Gigabit storage has become the limiting factor. RAID support adds the resilience expected in business storage, while the included rail kit simplifies installation in standard rack infrastructure. The TAA-compliant designation makes it easier to align with public sector and regulated procurement requirements. This is the kind of NAS you choose when storage is not just about holding data, but about keeping recovery windows tight, access predictable, and rack space under control. For teams comparing it against lower-cost desktop NAS options, the value is in the deployment profile: faster network access, rack-ready integration, and a form factor built for sustained use in a shared infrastructure stack.
