Buffalo SATA 3 Gb/s 2TB Replacement Hard Drive for LinkStation & TeraStation

The Buffalo OP-HD2.0BST-3Y is a 2TB SATA hard drive built as a direct replacement for drives inside LinkStation and TeraStation RAID enclosures. It gives you the space you need to keep large media libraries, project archives, or critical backups in one secure location while keeping the RAID array up and running.

Using a SATA 3 Gb/s interface, the drive maintains the data flow rates expected by Buffalo network storage, so everyday file transfers, media streaming, and scheduled backups stay smooth. Because it is engineered for Buffalo NAS units, there is no guesswork about firmware or compatibility.

The drive works seamlessly with LinkStation models 220, 420, and 720, along with TeraStation TS1200D and TS1400D. Home users who stream movies to multiple devices, creative professionals managing large photo sets, and small offices that rely on shared file access can all drop this drive into an empty or failed bay and resume normal operations in minutes.

Installation is straightforward. The drive measures 6.69 x 4.13 x 1.18 inches and weighs just 1.54 lbs, so you can handle it easily while following Buffalo’s quick-swap guide. Once in place, the existing RAID array will recognize the new disk and begin rebuilding automatically, limiting downtime.

Every drive ships with a 3-year warranty, giving you the assurance that Buffalo stands behind the hardware that guards your data.
