You are looking for buffalo terastation 71210rh 12 bay enterprise alternatives because this specific model may not match your exact infrastructure needs. The BUFFALO TeraStation 71210RH offers 10GbE connectivity and 12 bays in a rackmount chassis, but its fixed 80TB configuration and Intel Xeon processor might be too expensive or rigid for your workflow. You might prefer a different network speed, a different form factor, or simply a different brand that aligns better with your existing hardware ecosystem. Some users need more RAM for virtualization, while others require smaller footprints or additional drive bays.
We selected these options because their specifications overlap with the core requirements of the original device. The list includes other 12-bay rackmount units, such as the Asustor Lockerstor, which provides expandable RAM and 2.5GbE networking. We also included smaller 8-bay and 4-bay models from QNAP for teams that prioritize network speed over maximum drive capacity. These alternatives cover a range of storage densities and connectivity options, ensuring you find a device that fits your specific technical constraints without compromising on essential enterprise features.
Our top pick: BUFFALO TeraStation 12-Bay 80TB Rackmount NAS.
How each alternative compares
Asustor Lockerstor 12-Bay Rackmount NAS
The Asustor Lockerstor 12-Bay uses a quad-core processor and 8GB of RAM, offering expandable memory instead of the BUFFALO’s fixed Intel Xeon setup. It provides 2.5GbE and 5GbE ports rather than the 10GbE native to the BUFFALO. You get a lighter chassis at 25.8 pounds compared to the BUFFALO’s 54.2 pounds. This unit suits users who need virtualization support and lower network speeds but want easier RAM upgrades. It sacrifices raw CPU power and 10GbE speed for flexibility and a smaller footprint.
BUFFALO TeraStation 51220RH 12-Bay 240TB
This BUFFALO model shares the same rackmount form factor and 12-bay design but delivers 240TB of storage using twelve 20TB drives. It retains the enterprise security features and high-speed networking of the original. You gain three times the capacity without changing your chassis size. The weight increases slightly to 55.4 pounds. This option is for businesses that need maximum density and data protection in a single unit. It keeps the same brand ecosystem and reliability but scales capacity significantly higher than the 80TB baseline.
Asustor Lockerstor 16 Pro 16-Bay Rackmount NAS
The Asustor Lockerstor 16 Pro expands to 16 bays and includes 16GB of RAM with an 8-core AMD Ryzen processor. It offers dual 10GbE ports alongside 1GbE connectivity. This unit targets heavy virtualization workloads with ECC RAM support. You gain four extra drive slots and more processing power than the BUFFALO. The weight is 33.7 pounds. It is ideal for users who need more bays and stronger multi-tasking capabilities. It gives up the BUFFALO’s specific enterprise encryption features for higher computational performance and memory capacity.
QNAP 8-Bay Rackmount NAS with Redundant Power
The QNAP 8-Bay Rackmount NAS reduces the drive count to eight but maintains 10GbE connectivity alongside 2.5GbE and 5GbE ports. It features expandable memory for flexible networking speeds. You lose four drive slots compared to the BUFFALO but gain a more compact chassis. This unit suits users who prioritize network versatility over maximum storage density. It offers robust 10GbE performance in a smaller footprint. It is a good fit for environments where network speed is critical but high capacity is less important than in the 12-bay BUFFALO.
QNAP TR-004U 4 Bay Rackmount NAS
The QNAP TR-004U is a 4-bay expansion unit designed to add capacity to existing QNAP systems. It has a much smaller form factor and weighs only 4.41 pounds. You cannot use it as a standalone NAS like the BUFFALO. It is for users who need to expand their current QNAP infrastructure with physical security and RAID configuration. It lacks the standalone networking features and high capacity of the BUFFALO. This unit is a specialized add-on rather than a primary storage solution for new deployments.
QNAP 4 Bay 1U Rackmount SATA JBOD
The QNAP TL-R400S is a 4-bay SATA JBOD expansion unit for adding storage to QNAP NAS or server systems. It uses a SATA interface and rackmount design. You gain direct PCIe connectivity and rack efficiency but lose standalone NAS features. It is for users who need to expand existing storage arrays rather than buy a new NAS. It does not offer the networking, processing power, or integrated backup features of the BUFFALO. This unit is a specialized tool for capacity expansion within an existing ecosystem.
