Buffalo 8TB 3.5" Replacement Hard Drive HDD for TeraStation

The Buffalo OP-HD8.0N is an 8TB hard drive that lets you add fresh capacity or swap out a failed drive in your TeraStation with minimal effort. Because it uses the familiar 3.5-inch form factor and a SATA III 6 Gb/s interface, installation feels as straightforward as inserting any standard desktop drive, yet it delivers the sustained speed needed for busy NAS workloads.

An 8TB pool of space means you can centralize business documents, project archives, or an ever-growing media collection without juggling multiple smaller drives. Creative teams can keep high-resolution video footage at their fingertips, while small offices gain a reliable vault for daily backups and shared files.

Hot-swap support is built in, so you can replace the drive while the TeraStation stays powered on and serving data. For IT administrators, that reduces maintenance windows and keeps users productive. For home users, it means your Plex library or personal cloud stays online even during an upgrade.

The drive fits naturally into Buffalo TeraStation models such as the 5210DN, 5410DN, and 5810DN. Its compact 5.8 × 4 × 1-inch chassis and 1.63-pound weight make handling easy during installation or removal, whether you are working in a rack cabinet or on a desk.

Buffalo engineers this drive to match the performance and reliability expectations of the TeraStation lineup, so you can trust it to safeguard critical data and keep your NAS running at full speed.
