Buffalo 3TB Replacement Hard Drive for TeraStation 3410/5410 Series

The Buffalo OP-HD3.0N is a 3 TB replacement hard drive built for TeraStation 3410 and 5410 series enclosures, giving administrators a simple path to restore capacity or expand a RAID array without taking the system offline. It connects through the SATA III interface and fits into a standard 3.5 inch bay, so installation feels familiar even if you have never worked on a TeraStation before.

Buffalo engineered this drive for hot-swap operation inside the 3410DN, 3410RN, 5210DN, 5410DN, and 5410RN models. When a drive fails or when you need extra space, you can pull the old unit, slide this one in, and let the array rebuild while users keep working. The 6 Gbps transfer rate supports quick backups, smooth file sharing, and steady video streams that many creative studios and small businesses rely on.

This model arrives in a protective internal carrier that aligns perfectly with the TeraStation locking mechanism, so there is no fiddling or extra brackets. Because it meets RoHS guidelines, the drive helps organizations stay compliant with environmental standards. Buffalo backs the hardware with a three-year warranty, giving IT teams confidence that their data is resting on a dependable platform.

Whether you manage a branch office file server, a surveillance archive, or a media library, the OP-HD3.0N lets you address drive failures or planned expansions quickly, keeping projects on schedule and users happy.
