Buffalo TeraStation 51220RH 64TB 12-Bay NAS Server

The Buffalo TS51220RH6404 is a rackmount network attached storage system that arrives with 64TB already in place, thanks to four installed 16TB drives. Twelve drive bays give you room to grow far beyond the starting capacity, making this unit a practical long-term home for file servers, media libraries, backups, or virtual machine data.

Inside the enclosure, a 2.04 GHz Annapurna Labs AL524 processor works with 16 GB of DDR4 memory. The combination handles heavy read and write workloads, so teams can edit large projects directly from the NAS or push daily backups without slowing down the network. Dual 1 GbE ports cover everyday connectivity, while two 10 GbE ports unlock multi-gig transfer speeds for bandwidth-intensive tasks such as 4K video editing or rapid disaster-recovery replication.

Data protection features are built in. You can choose from RAID 0, 1, 5, 6, 10, or JBOD, and the hot-swap design lets you replace a failed drive on the fly. Hardware-level 256-bit encryption safeguards information at rest, and optional two-factor authentication keeps unauthorized users out of the dashboard.

The TeraStation works neatly with popular cloud services. Set up scheduled or real-time sync with Dropbox, Amazon S3, or Microsoft Azure to create an off-site copy without extra software. This hybrid approach gives small and medium businesses a straightforward way to meet compliance requirements and shorten recovery time after an outage.

Whether you run a creative studio that captures large raw files, an office that needs centralized document storage, or a branch location that sends data back to headquarters overnight, this NAS provides the capacity, speed, and resilience to keep work moving. Buffalo backs the unit with a three-year warranty and offers US-based support around the clock, with an optional five-year extension for businesses that want an even longer service window.
