Summary: I've worked with several different QNAP units and while they are great little units this one is a bit under-powered, if you can afford a TS-259 instead of this unit I'd pay the additional cost. The power of the dual-core Atom, dual NIC, and expandable memory is worth the additional cost.
Summary: I bought this NAS a year ago for home use with two enterprise disks for mirroring. The device seems working as it is supposed to do. But one of the anti-feature is the USB One Touch Copy. It never works as expected. I wanted to backup all files to a USB drive in case the NAS crashes. After contacting QNAP, I was told that users need to add every directory/sub-directory names to the folder list for the job. It is not feasible for normal users.
Summary: I've owned this QNAP product for a year now. I'm using it with 2x 2TB WD RED's as single disks. Everything you read about QNAP's quality and hardware is true. When comparing QNAP (side by side) to it's competitors (like models) QNAP units typically have more powerful processors and more installed memory. Do QNAP devices often cost a little more.. Yes. You do however get what you pay for. Some of this is in quality, but the majority is in performance and features.
Excellent up to the point you want to use it to print.

Summary: As far as this goes from a NAS perspective and streaming and dealing with data i cannot fault it. The front end to configure the system is extremely easy to use and got everything i wanted to work, EXCEPT printing. I was absolutley not expecting my current printer to work and as such knew i would probably need a new printer. QNAP provide a list of printers but how wrong was i in terms of getting a new printer.
