The Buffalo OP-HD12.0H2U-5Y is a 12TB hard drive that keeps TeraStation rackmount servers running smoothly. Designed for the 51210RH, 51220RH, and 71210RH models, it installs in the existing 3.5 inch trays without tools or extra brackets, so your array is back to full strength in minutes.
Because the drive supports hot swap, you can replace a failing disk or expand storage while the NAS stays online. That matters when the server is hosting team shares, virtual machine images, or surveillance archives that cannot afford downtime.
The 6 Gb/s SATA interface moves large files quickly, letting creative teams push and pull 4K video, engineers open CAD libraries, and administrators finish overnight backups on schedule. Buffalo builds the drive to enterprise standards and backs it with a five-year warranty, making it a reliable choice for offices, studios, and data closets that need continuous operation.
Highlights:- 12TB capacity provides room for large projects and long-term backups
- Fits TeraStation 51210RH, 51220RH, and 71210RH rackmount enclosures
- Hot swap support allows drive changes without shutting down the NAS
- 6 Gb/s SATA connection delivers fast transfers and quick rebuilds
- Enterprise-grade components and a five-year warranty add peace of mind
