Our take on the Buffalo OP-HD3.0QH 3TB 7200RPM SATA 6Gb/s 3.5-Inch Internal Hard Drive for DriveStation

This is a 3TB, 7200 RPM, 3.5-inch SATA hard drive sold by Buffalo as a replacement or expansion unit for its DriveStation storage systems. It is a plain desktop-class mechanical drive, not a NAS-specific model, so it is meant to slot into a Buffalo enclosure rather than run 24/7 in a server. Buyers get a large capacity and a standard SATA connection, but the drive is older stock with a SATA/300 interface and no advanced NAS firmware features. It suits someone keeping an existing DriveStation alive, not someone building a new array.

Cons
  • Not a NAS-rated drive; no vibration or error-recovery tuning for RAID

Questions and answers

Will this drive work in a non-Buffalo enclosure?
It is a standard 3.5-inch SATA drive, so it will physically fit most desktop bays and enclosures. Buffalo positions it for its own DriveStation systems, and RAID enclosures may reject drives without matching firmware.
Is this a NAS drive?
No. It is a desktop-class 7200 RPM drive without the vibration control and RAID error-recovery timing that NAS drives carry. It is fine for single-drive use and light backup duty.
Does the SATA/300 interface slow it down?
SATA/300 tops out around 300 MB/s, which is above what this mechanical drive sustains. The interface is not the bottleneck; the spinning platters are.
What is included in the box?
Expect the bare drive only. Mounting screws and a SATA cable are not confirmed as included, so check before installing.
Can I use it to expand a DriveStation Duo?
Yes, it is listed as compatible with the DriveStation Duo. Match the capacity and model of the existing drives if you plan to run them in RAID.
How long will a 3TB drive like this last?
Mechanical drives typically run several years under normal use, but this is older stock. Back up anything important and check the drive's health after installation.
