TrustedReviews have looked at the QNAP TS-109 Pro Turbo Station

When we reviewed the Synology CS-407e we thought it wasn’t possible to get any more features at this price point but QNAP has proved us wrong. Overall performance is particularly good and although the Download Station feature is of limited value there’s little this box can’t do - the backup features are also a cut above the rest.
