Our take on the Buffalo OP-HD4.0BST-3Y 4TB 7200RPM SATA 3.5-Inch Internal Hard Drive

This is a 4TB, 7200 RPM SATA 3.5-inch internal hard drive sold by Buffalo as a spare replacement for its LinkStation 220/420 and TeraStation 1200/1400 NAS units. It is a plain desktop-class drive, not an enterprise or NAS-rated model, so its main value is fitting a Buffalo enclosure with a part the vendor lists for it. Buyers who need a drive for a PC or a generic NAS should compare it with NAS-rated drives from Seagate, WD and Toshiba, which carry vibration and workload ratings this drive does not advertise. For anyone restoring a Buffalo NAS to service, it is the straightforward match.

Pros
  • Listed by Buffalo as a compatible spare for specific LinkStation and TeraStation models
  • 4TB capacity and 7200 RPM spindle give solid sequential throughput for a 3.5-inch drive
  • Standard SATA interface and 3.5-inch form factor fit the target enclosures directly
  • Simple swap for a failed drive in a supported Buffalo NAS
Cons
  • Not marketed as a NAS-rated drive, so no published workload or vibration rating
  • 7200 RPM desktop drives run warmer and louder than 5400 RPM NAS drives
  • Carries a Buffalo part number, which limits its use as a general-purpose upgrade
  • No SMART or firmware details published beyond the basic SATA spec

Questions and answers

Will this drive work in a LinkStation 220 or TeraStation 1200?
Yes. Buffalo lists it as a spare for the LinkStation 220 and 420 and the TeraStation 1200 and 1400. Check your exact model and firmware before buying, since Buffalo's compatibility lists change over time.
Can I use it in a regular PC or another NAS brand?
It is a standard 3.5-inch SATA drive, so it will physically connect. However, it is not rated for NAS workloads, so a NAS-rated drive is the safer choice for 24/7 use or RAID arrays.
Is it a NAS-grade drive?
No. Buffalo sells it as a replacement part, and it does not carry the workload or vibration ratings that NAS drives from Seagate, WD or Toshiba advertise.
How loud and hot does it run?
At 7200 RPM it spins faster than 5400 RPM NAS drives, so expect more noise and heat. Good airflow in the enclosure matters.
Does it come with a warranty?
Buffalo's part number includes a three-year designation, which reflects the warranty term Buffalo attaches to this spare. Confirm the terms with the seller for your region.
What is in the box?
The drive itself. Mounting screws, trays and cables are not included, so reuse the caddy from the drive you are replacing.
