Buffalo TeraStation Duo 1TB review

Our Rating :
Price when reviewed : £238
inc VAT

A good NAS, but it's shockingly expensive for a 1TB model.


2 disk bays, 2x 500GB storage supplied, 2x 10/100/1000Mbit/s Ethernet ports

With its two removable disk trays, the Buffalo TeraStation Duo 1TB looks like a shrunken, smaller version of its larger, more expensive, four-disk counterparts. A small front-mounted LCD display shows status information, such as the current IP address and the health of the RAID array. The heavy, metal case feels reassuringly sturdy and the fan was barely audible in our tests.

The trays are hidden behind a lockable front door. Although harder to pry open than previous TeraStations, the lock will still only deter casual data thieves – the door can be forced open with only moderate effort. The trays themselves hold the disks in place using screws, so they’re easy enough to swap out whether you’re replacing a faulty disk or simply adding more storage capacity.

Configuring the TeraStation is blissfully straightforward, thanks to the friendly discovery utility and the logically organised web admin interface. The tabbed layout makes it easier to find the control you’re looking for. User accounts can be created quickly and there are options for setting usage quotas and organising those accounts into groups for easier administration, all accessible from within the same screen. To prevent you from accidentally erasing all your data, the interface requires you to retype an onscreen numeric code before changing your RAID array type.

The TeraStation fared very well in our demanding file transfer benchmarks. Whether configured as either RAID 0 or 1, it transferred large files at an average speed of around 30MB/s. Small files were copied at an average speed of just over 16MB/s – another excellent result.

We had no trouble using it as UPnP media server, with HD videos streaming smoothly to a network media player. We couldn’t get it working as an iTunes music server for the iTunes client, though. We had better luck using the TeraStation to share a USB disk and a USB printer with computers on our network – these features worked without a hitch.
