12 TB SATA Replacement Drive

This 12 TB SATA hard drive is designed as a direct replacement for specific Buffalo Terastation models. It uses a standard SATA 600 interface and fits the internal drive bays of the compatible units. The drive provides high-capacity storage for network-attached storage systems.

Suits TS51210RH owners; not for other systems

This drive is validated for the TS51210RH4804 and TS51210RH14412 Terastation units. Buyers with different NAS models or those needing a standalone external drive should look elsewhere. It is not a general-purpose internal drive for PCs or servers outside the listed compatibility.

12 TB capacity for array rebuilds

The 12 TB capacity matches the original drive specifications for the supported Terastation models. It comfortably handles full array rebuilds and bulk data storage within those systems. Headroom is defined by the fixed drive bay count of the host unit.

Questions about this item

Which NAS models does this 12 TB SATA drive officially support?

It is validated for the TS51210RH4804 and TS51210RH14412 Terastation systems.

Will the 1.1" high drive fit in a bay designed for 1.06" drives?

The 1.1" height is the installed dimension; the 1.06" figure is the bare drive. Both refer to the same physical unit and will occupy a standard 3.5" bay.

How can I confirm the drive is running at SATA 600 speed after installation?

Check the Terastation management console — it reports the negotiated link rate for each bay.
