Buffalo 12TB Spare Hard Drive for TeraStation NAS Series

The Buffalo OP-HD12.0N is a 12TB spare hard drive built specifically for TeraStation NAS systems. It slides into any open bay on TeraStation 3010, 3020, 5010, 5020, WS5020, and 6400 models without tools, so you can expand capacity or swap out a failing drive in minutes while the NAS stays online.

Inside, the 3.5-inch drive uses a SATA 6 Gb/s interface that pushes data at up to 600 MB/s. That bandwidth keeps large file transfers, scheduled backups, and virtual machine workloads moving smoothly, even during peak usage.

With 12 TB available, departments that handle video footage, design assets, or large backup sets gain plenty of headroom before space becomes a concern. For IT teams, the drive provides an easy path to scale storage pools, rebuild RAID arrays, or restore redundancy after a drive failure.

Because the OP-HD12.0N is qualified by Buffalo for the listed TeraStation families, you avoid compatibility guesswork and keep full support coverage. A three-year warranty backs the drive, giving businesses added peace of mind in demanding environments such as corporate offices, creative studios, and branch locations.
