Purpose-built replacement drive

This 4 TB internal hard drive is manufactured by Buffalo Technology specifically as a replacement part for TeraStation 1200D and 1400D families and LinkStation 220D and 420D families. It is intended for owners of those Buffalo NAS units who need to restore capacity after a drive failure or expand an existing array with a matched component. The drive is not suited for builders assembling a custom server or desktop who require a standard off-the-shelf unit with broad controller compatibility.

Compatibility constraint

The drive is validated only for the TeraStation 1200D, 1400D, LinkStation 220D and 420D product families listed by the manufacturer. Using it in other enclosures, RAID controllers or direct-attached configurations is not supported by Buffalo and may result in unrecognised firmware, incorrect spin-up behaviour or RAID rebuild failures. Buyers who need a drive for a different NAS brand, a generic USB enclosure or a workstation should select a model qualified for that platform.

Questions about this item

Should I choose the 4.0 TB model for a TeraStation 1200D or a 1400D?

The 4.0 TB drive is a direct replacement for both TeraStation 1200D and 1400D families, so either system will accept it.

What does the 4 TB capacity mean inside a LinkStation 220D?

It provides a single 4 TB volume for the LinkStation 220D, restoring the original storage amount without RAID expansion.
