Keep business files accessible on a compact NAS built for dependable shared storage. The Buffalo TeraStation 5420DN arrives partially populated with 8 TB installed across two 4 TB drives, giving teams a practical starting point for file services, backups, and departmental data. With 10 GbE connectivity, it can move beyond basic office storage and support faster access for users who depend on large file transfers and frequent collaboration. RAID support helps align capacity with the level of protection your environment requires, while iSCSI support adds flexibility for block-based workloads that need a simple, rack-friendly storage target. The desktop form factor keeps deployment straightforward for branch offices, workgroups, and smaller infrastructure footprints where space is limited but data availability still matters. TAA compliance makes this model suitable for procurement environments with sourcing requirements, and the partially populated design gives you a lower entry point than fully loaded arrays without forcing a compromise on core storage features. For teams that need a business NAS with stronger network headroom than entry-level units, the 5420DN is positioned to carry shared data with more confidence and less friction.
