A 4.0 Tb 3.5 inch Sata hard drive for Drivestation Ultra NAS replacement

4.0 Tb Sata drive for Drivestation Ultra

This 4.0 Tb 3.5 inch Sata hard drive serves as a direct replacement for the Drivestation Ultra HD-DN040T/R6. It restores the full 40 Tb raw capacity of the original network-attached storage array. The drive installs internally using the standard Sata interface. It is intended for owners of that specific Buffalo enclosure who need to replace a failed or degraded disk.

Supplied as a bare drive without caddy or rails

The package contains only the hard drive mechanism itself. No mounting brackets, screws, drive tray or management software are included. Buyers must reuse the original carrier from the Drivestation Ultra chassis. This product does not suit users who need a complete hot-swap module or a standalone external drive.

Highlights

  • 0 TB capacity stores large NAS datasets
  • 5 inch form factor fits standard drive bays
  • SATA 6Gb/s interface enables fast data transfer
  • RoHS compliant build meets environmental standards

Questions about this item

Will the 4.0 Tb Sata drive inside this server need a firmware update or a mechanical swap after a few years?

The drive is a standard 3.5 inch Sata unit rated for continuous NAS operation; plan a mechanical swap once its rated workload or error counters reach the vendor limit.

What limit appears first when the 4.0 Tb drive runs sustained writes — the Sata 6 Gb/s interface or the drive's own throughput?

The drive's native sustained transfer rate is the bottleneck; the Sata 6 Gb/s link has headroom above what the mechanical platters can deliver.
