Protect critical workloads with a rack-mounted NAS designed for backup, recovery, and shared storage in busy infrastructure environments. The TeraStation 51220RH ships with 80 TB installed across four 20 TB enterprise drives, giving teams immediate usable capacity without the delay of a separate build-out. Its 2U chassis fits cleanly into standard racks, while 10 Gigabit Ethernet helps move large backup sets and restore jobs without bottlenecking the network. This system is built for administrators who need dependable storage behavior, not consumer-grade simplicity. RAID support adds the fault tolerance expected in production environments, and iSCSI support gives you flexibility when integrating the array into mixed storage workflows. The included rail kit simplifies deployment, and TAA compliance makes it suitable for procurement environments with sourcing requirements. For organizations that need to protect virtual and physical environments while keeping operations manageable, this model offers a practical balance of capacity, connectivity, and rack efficiency. It is a stronger fit than entry-level NAS appliances because it is sized for sustained backup traffic and enterprise deployment discipline.
