Capacity and audience

The Buffalo DriveStation Duo HD-WH4TU3R1 delivers 4TB of external storage across two internal drives. It targets creative professionals and small offices that need a single, reliable volume for project files and scheduled backups.

Sustained operation

Two NAS-rated hard drives are built for continuous 24/7/365 duty rather than intermittent bursts. RAID 1 mirrors data in real time and hot-swappable bays let a failed drive be replaced without powering down the array.

RAID flexibility

The hardware controller supports RAID 0 for maximum capacity and speed or RAID 1 for redundancy. Buyers who need a portable single-drive device or hardware encryption should look elsewhere.

Questions about this item

How much noise and heat does the DriveStation Duo produce when it runs 24/7/365?

The unit contains two high-performance NAS hard drives built for continuous operation; typical desktop RAID enclosures with active cooling emit a low, steady fan hum and warm exhaust air under sustained load.

What computer ports and operating systems are required to use the USB 3.0 interface?

A USB 3.0 or USB 2.0 port on a PC or Mac is sufficient; the drive draws power from the included AC adapter, so no bus-power capability is needed on the host side.

Can I keep using my existing USB 2.0 hub or docking station with this array?

Yes — the drive falls back to USB 2.0 mode at up to 480 Mb/s through any standard USB 2.0 connection, although transfer speeds will be lower than the 5 Gb/s USB 3.0 maximum.
