The Western Digital ShareSpace (WDA4NC20000) is fast and comes bundled with two excellent 1TB hard drives, but it suffers from a slightly higher price tag than competing units and has a fragile interior racking system.

If you're looking for a simple and attractive storage device that you can access via networking options, then the LaCie Network Space may very well be the one for you. Just make sure you don't mind its lack of expandability and features.

Although the DS408 certainly has good software and strong multimedia capabilities, it is ultimately let down by a poor case design that restricts the ability to hot-swap hard drives. This will suffice for home use, but is inadequate for situations where data integrity is a must.

Combining exceptional scalability, stellar performance, powerful storage applications, and management tools that make even the most complex tasks seem easy, the BlueArc Titan 3000 sums up the best of what you can expect in a file serving system. The Titan is a good fit for demanding environments, where its scalability and admin-friendly features can offset a somewhat challenging price.

The N3200 is slower than some other drives on offer, but its performance was about same as a four-drive Iomega StorCenter 150D. It offers innovative functions and is easy to use. So considering the fair price, the Thecus N3200 is a clear winner that offers good value for money.

This is an efficient and effective NAS system for businesses.

The Aspire EasyStore is pricey compared to the competition, but it is fast and easy to use.

The 2big network's main flaw is that it was far slower than other drives we've looked at. Even considering the low price, and that some of these drives had three or four drives to the 2big's two, its performance was poor.

The TS-409 Pro has a number of features suited to both business and home storage, so it’s a little perplexing trying to figure out its target market. Although the unit’s only distinguishing feature is the somewhat illogical inclusion of RAID-6, its price and basic features are reasonable.

The DNS-343 is a simple to use NAS device that is also easy to set up. It doesn’t offer anything unique, but it's largely well-designed and is a decent option for the tech-savvy and novices alike.
