QNAP’s attention to the quality of the components used in the construction of the TS-409 is refreshing to see, and still they have proven quality doesn’t automatically mean a higher price. At $550 for the non-Pro and $600 for the Pro version the TS-409 is priced well below most of their competitors. The TS-409 incorporates many Enterprise-grade features one would expect to see in a NAS that costs almost half again this amount, and as such literally blows away four-bay NAS solutions within its price range by offering a better value, feature set, and very strong performance.
