Option Partially Populated

  • 48 TB raw capacity with four pre‑tested enterprise drives
  • 16 GB DDR4 ECC memory for data‑integrity protection
  • Four 10 GbE ports plus 5 GbE and 2.5 GbE support

Built for enterprise storage teams

The Buffalo TeraStation 71210 is a 12-bay rackmount NAS delivered with four 12 TB enterprise drives for 48 TB raw capacity. It ships in RAID 6, yielding 24 TB usable space, and includes 16 GB DDR4 ECC memory plus four 10 GbE ports. The unit targets IT departments that need immediate, high-throughput shared storage with snapshot backup and Btrfs data integrity.

Suits teams wanting 10 GbE and SSD caching ready

Organisations that require 25 GbE or 40 GbE uplinks can populate the two PCIe Gen 4 x8 slots with compatible network cards, while the OP-NVSSD series adds high-speed cache. Buyers who need more than four pre-installed drives, a different file system, or a tower form factor should evaluate other platforms.

Ships with 48 TB raw in RAID 6 for 24 TB usable

The four included 12 TB drives arrive pre-configured in RAID 6, providing dual-drive fault tolerance and 24 TB of protected capacity. Rebuilding to RAID 0 unlocks the full 48 TB but removes redundancy, so the default RAID level is the decisive specification for data-critical deployments.

Questions about this item

How do I confirm the TeraStation 71210 is operating correctly after initial setup?

Log into the web management console and verify all four 12 TB drives show healthy status, the RAID 6 array reports 24 TB usable capacity, and the four 10 GbE ports display active link lights at the expected speed.

What ships with the unit and what must I purchase separately to expand it?

The rackmount chassis arrives with 48 TB of enterprise drives pre-installed in RAID 6, 16 GB DDR4 ECC memory, an internal 100–240 V power supply, two USB 3.2 Gen 1 ports and two USB 2.0 ports. Additional OP-HDHU2 hard drives, OP-NVSSD SSDs or OP-ECCMEM-16G memory modules are sold separately.

Which RAID mode should I select for maximum usable space versus data protection on the included 48 TB?

The default RAID 6 provides 24 TB usable with two-drive fault tolerance. RAID 0 unlocks the full 48 TB but has no redundancy. RAID 10 also yields 24 TB with mirrored pairs, while RAID 5 would require a different drive count to calculate usable space.
