Replacement drive for TeraStation and LinkStation

The Buffalo Technology OP-HD1.0BST-3Y is a 1 TB internal hard drive built as a direct replacement for specific Buffalo NAS appliances. It supports TeraStation 1200D and 1400D families as well as LinkStation 220D and 420D families. The drive is sold new and intended for owners of those models who need to restore or expand their storage array.

Capacity and headroom

The drive provides 1 TB of storage capacity for the compatible NAS units listed above. It fills the exact drive bay and firmware expectations of those TeraStation and LinkStation families. Systems outside the 1200D, 1400D, 220D and 420D lines are not supported, so buyers with other NAS models or generic PC builds cannot use this drive.

Thermals noise and power draw

As a standard 3.5-inch mechanical drive designed for NAS enclosures, it operates within the thermal and acoustic limits of the target TeraStation and LinkStation chassis. Power consumption matches the original drive specifications for those families, allowing the NAS to manage cooling and power budgets without modification. No additional cooling or power changes are required when installed in the supported devices.

Questions about this item

Will this 1 TB drive fit into my existing TeraStation 1400D enclosure?

It is built as a direct replacement for TeraStation 1200D and 1400D families, so it matches the drive bay and connector layout of those units.

How can I confirm the drive is recognised after installing it in a LinkStation 420D?

The NAS management interface will list the new 1 TB volume once the rebuild or initialisation finishes, showing healthy status and full capacity.

Does the package include mounting screws or a drive tray for the 1200D chassis?

Retail or OEM packing may vary, so the box contains only the bare drive; any screws, trays or caddies must be reused from the old drive or sourced separately.
