You don't need me to tell you why NAS devices are just about the best thing since sliced bread. Aside from the peace of mind afforded by knowing all of your critical data is safely backed up in the event of your PC kicking the bucket, said files can also be accessed from multiple computers or even, if you store media on your NAS, by a games console or TV. It is, as the kids say, "pretty rad."
Buffalo has been in the business of making NAS devices for a long time now and it's produced some excellent examples - an original TeraStation served as TrustedReviews' storage repository for several years. This particular model is pitched as an upgrade to the LinkStation Pro Duo and despite dropping "Pro" from its name should prove the superior device.
For a device that's never likely to be a centrepiece of your home computing setup the LinkStation Duo looks attractive enough. Its compact dimensions of 86mm x 204mm x 127mm should help with hiding the device out of the way should you so desire. Plus the Duo isn't intrusively loud unlike some NAS devices I've had the (dis)pleasure of testing.
As the name betrays, the LinkStation Duo is a two bay NAS device, available in configurations of either 1TB, 2TB or 4TB - fitted with two 500GB drives, two 1TB drives or two 2TB drives respectively. These can be configured in either RAID 1 or RAID 0, or with each drive showing separately - the foremost of which is obviously the safest.
The two hard drives are accessed by popping off the front cover, revealing two quick-release bays. As such, it's the work of a moment to pop out an old drive and place in a new one. There's no facility for upgrading the Duo's storage capacity in-place, but that's hardly a major criticism; just be sure to pick the right drives initially.
