Benchmark Reviews posted a review on the QNAP TS-509 Pro Gigabit 5-Bay SATA NAS Server

When corporate funds are tight, companies find new ways to reduce operating costs wherever they can. As a network administrator for several small and medium businesses, I'm used to seeing pedestal servers with expensive Windows Server edition Operating Systems running for the sole purpose of serving files out to the workgroup or domain. These environments have made it necessary to look for money-saving opportunities elsewhere in the office environment. A few years back Network Attached Storage server hit the scene with a price tag comparable to the alternative, but the NAS products offered in today's market are far superior and cost much less than before. QNAP offers many affordable NAS server solutions for every department size, and their Turbo Station TS-509 Pro delivers feature-rich functionality to the enterprise environment. In this article, Benchmark Reviews tests the performance of the 5-drive hot-swappable SATA Gigabit NAS server.
