Move more data with less friction using the Buffalo TeraStation 5420DN NAS 32TB. This 4-bay desktop NAS arrives with 4 x 8 TB NAS hard drives installed, providing 32 TB of capacity out of the box and a clean path for organizations that need substantial shared storage without building a full SAN. The 10 GbE network interface is the key differentiator here. It gives this model the bandwidth needed for larger file transfers, multi-user access, and storage workflows that outgrow standard Gigabit NAS appliances. RAID support and iSCSI add the resilience and flexibility expected in business storage, while the TAA-compliant designation makes it suitable for procurement environments with sourcing requirements. For IT teams, the 5420DN sits in the right place when performance matters enough to justify the spend. It is not just about capacity; it is about keeping data local, accessible, and ready for workloads that need faster throughput and more predictable control than lower-tier storage can provide.
