We test a dozen or so NAS servers every year, but have never come across such a low cost unit until the Patriot Valkyrie hit our office. Patriot has managed to deliver a product that everyday consumers have asked for at a price that those users can afford. The feature set of the Valkyrie is advanced and useful without being overbearing and complicated.
When it comes to the performance, the Valkyrie is able to do common tasks at a speed average users can appreciate. It should be said to not expect blistering performance like the enterprise models that we are accustomed to testing, but to get that level of performance you are going to pony up 4x of the cost of the Valkyrie.
Speaking of the price, at 145 after a mail in rebate, Amazon already has units in stock and ready to ship. Newegg lists the Valkyrie but the price is not yet published and they do have stock available. At this price there is no reason why just about every digital household should not have a NAS taking care of their digital entertainment storage needs.
