12-Bay Rackmount NAS with 64TB

The Buffalo TeraStation 51220 is a 12-bay rackmount network-attached storage unit pre-populated with four 16TB enterprise-grade hard drives for 64TB raw capacity. It runs on 16GB DDR4 memory and includes a native 10GbE port alongside multi-gigabit Ethernet standards. The system arrives RAID pre-configured and supports RAID 0, 1, 5, 6, 10, and JBOD modes for flexible data protection.

Suits businesses needing high-capacity.

This unit fits organisations that want a pre-tested, virtualization-certified appliance compatible with Windows Server 2022, VMware, and major cloud targets such as Amazon S3 and Azure. It is not for buyers who need more than twelve drive bays, require a different drive interface than SATA, or operate outside the 0°C to 40°C temperature range.

Native 10GbE port for high-speed transfers

The single specification that decides fit is the onboard 10GBASE-T port, which delivers ten-gigabit Ethernet over standard copper cabling without requiring fibre upgrades. If your network infrastructure stops at 1GbE, the extra throughput will remain unused; if you already run 10GbE or 2.5/5GbE switches, the NAS can saturate those links for large-file workloads and backup windows.

Perguntas sobre este artigo

Should I pick the 64TB version or add more drives to the empty bays?

The unit ships with four 16TB drives for 64TB raw capacity. Eight bays remain free so you can expand later without buying a second appliance.

What does the 10GbE port deliver in daily file transfers?

The native 10GBASE-T port supports up to 10Gbps over standard Cat6a cabling, so large project folders move at near line speed without extra adapters.

Which network standards does the RJ-45 port actually support?

It negotiates 10GBASE-T, 5GBASE-T, 2.5GBASE-T, 1000BASE-T, 100BASE-TX and 10BASE-T automatically, capping at the highest speed both ends share.
