Give your storage stack more headroom with the Buffalo TeraStation 5820DN 64 TB NAS. This partially populated system ships with 4 x 16 TB drives installed and 4 open bays, so you can start with meaningful capacity and add storage as demand grows. That makes it a practical fit for IT teams balancing near-term budget control with future expansion. 10 Gigabit Ethernet helps keep file services and backup traffic moving efficiently across the network, while iSCSI support extends the platform into server and virtualization use cases. The TAA-compliant design supports procurement requirements where sourcing matters, and the open-bay layout reduces the need for a full replacement when storage needs increase. Compared with smaller fixed-capacity NAS appliances, this model gives infrastructure teams a cleaner upgrade path. It is built for organizations that want a storage platform that can absorb growth, support shared workloads, and stay manageable as the environment becomes more demanding.
