Benchmark Reviews tested the QNAP TS-409 Pro 4-Drive SATA Gigabit NAS.

Quote from the review: "Times are a little tough right now for many small business owners, so any product that offers to save them money while still performing every function they require is sure to interest many of them. The task of providing an affordable product, that cuts overhead yet still performs up to par is not any easy undertaking. Most small businesses today have at least some level of data storage needs.
It may be as simple as storing bookkeeping records, emails and customer contact information, it may involve storing legal documents or patient records, it may involve storing work product such as digital artwork or CAD drawings, or it may even involve hosting the company's retail sales website. The bottom line is that in today's business world it is hard to find a small business that doesn't have some need to store their digital data. This is where the Network Attached Storage servers come in and today Benchmark Reviews will be taking a close look at one of these NAS Servers, the QNAP TurboStation TS-409 Pro."
