Replacement drive for TeraStation arrays

The Buffalo Technology OP-HD10.0N is a 10TB rackmount NAS hard drive built as a direct replacement for specific TeraStation models. It targets administrators who need to restore capacity or swap a failed disk in supported units without changing firmware or cabling.

Upgrades capacity in 5010 3010 3020 WS5020 6400

This drive replaces smaller factory-installed disks in the listed TeraStation series. The jump is worth it when an array has hit its storage ceiling and the chassis cannot accept additional bays. It is not suited for non-TeraStation servers or for builders who need hot-spare flexibility across mixed hardware.

Slide-in installation with RAID rebuild

The drive fits the standard carrier used by the compatible TeraStation models, so installation is a simple slide-and-lock action. The main risk is inserting a single disk into a degraded RAID set without verifying the array health first, which can trigger a lengthy rebuild and leave the volume unprotected until it finishes.

Questions about this item

Will the 1.03" x 4.00" x 5.79" drive tray slide into a TeraStation 5010, 3010, 3020, WS5020 or 6400 series bay?

Yes, the OP-HD10.0N is built to the exact 1.03 by 4.00 by 5.79 inch form factor required by those TeraStation models, so it seats directly in the hot-swap bay.

What is the correct way to seat the 1.63 lb drive module in the rackmount chassis?

Hold the module by its edges, line up the guide rails with the bay, slide it in until the front face is flush, then engage the locking lever to secure the 10 TB unit.

When should the 10 TB replacement drive be swapped out in a RAID array?

Replace the OP-HD10.0N immediately if the TeraStation reports a SMART error, a degraded RAID status, or after the drive reaches the manufacturer-rated workload limit.
