12 TB replacement drive for TeraStation

This 12 TB hard drive is designed as a direct replacement for compatible Buffalo TeraStation units. It uses a SATA 6.0 Gb/s interface and fits the 3.5 inch form factor used by the listed NAS models. The drive arrives new and ready for installation in a supported enclosure.

Compatibility and use cases

It suits owners of TeraStation 5010, 3010, 3020, WS5020 and 6400 series devices who need to replace a failed drive or expand available capacity. Builders looking for a standalone external drive, a laptop upgrade or a drive for a non-Buffalo NAS should look elsewhere because this unit is validated only for the specified TeraStation series.

SATA 6.0 Gb/s interface

The drive communicates over a SATA 6.0 Gb/s connection, which determines whether it will work in your TeraStation bay. Verify that your NAS model appears in the supported series list before purchase, as the interface and firmware tuning are specific to those systems.

Questions about this item

Does the SATA 6.0 Gb/s interface limit real-world throughput to 6 Gb/s?

The drive uses a SATA 6.0 Gb/s interface, which caps the theoretical maximum transfer rate at 6 Gb/s; actual throughput depends on the host controller and system workload.

Will this 1.03" x 4.00" x 5.79" drive fit my TeraStation 5010 bay?

The drive measures 1.03" x 4.00" x 5.79" and weighs 1.63 lbs., matching the 3.5-inch form factor used in TeraStation 5010, 3010, 3020, WS5020 and 6400 series bays.

How do I install the OP-HD12.0N, and what step do people often miss?

Power down the NAS, slide the drive into an empty bay until the SATA connector seats firmly, secure it with the bay lock or screws, then power on and run the RAID rebuild or volume expansion in the TeraStation management console.
