Keep backup data close, recover faster, and preserve rack space with the Buffalo TeraStation 5420RN 48TB 1U NAS. This appliance is built for teams that need dependable storage density without adding complexity to the rack. With 48 TB of included capacity across four 12 TB drives, it gives you immediate usable storage for backup repositories, shared data, and retention-heavy workloads. 10 Gigabit Ethernet helps move large backup sets and restore jobs without bottlenecking the network, while RAID support adds the fault tolerance expected in production environments. The 1U rack-mount design fits cleanly into standard infrastructure layouts, and the included rail kit simplifies deployment. iSCSI support broadens integration options for environments that need block access alongside NAS workflows. For procurement teams, the TAA-compliant designation matters. For infrastructure teams, the value is straightforward: a compact appliance that delivers capacity, speed, and resilience in a form factor designed for the data center floor. It is a practical fit when you need to protect more data per rack unit and keep recovery paths predictable.
