Summary: After a year of having this device I think I will never again buy another Qnap product. The amount of problems from one firmware to the next is atrocious, I cannot tell you how many times a firmware update will solve one problem and break multiple other things, I feel as though they use the general public to QA their products. Some of the most common issues I've run into are: 1. Processor pegged at 100% for days.
VMWARE & iSCSI feature set is incomplete / poor support

Summary: I find the product lacking in its redundancy feature set and customer support. This comes from first hand experience during the failure of a drive in the QNAP TS-879U-RP, 8 drive product, in January 2013. I am writing to update this review in May 2013. My issues are not solved. In addition, what I had believed to be a VMWARE VMOTION issue, VMWARE has been able to reproduce and has communicated the problem is with QNAP firmware issue that isn't solved.
Summary: Purchased two of these. Within 24hours one failed. No power, no lights, just dead.Called QNAP and was told they didnt do advanced replacements. They told me I needed to send this unit in first then they would send me a replacement. The process would take around two weeks. I told them this was unacceptable for a brand new item and finally got them to agree to send an advanced replacement.
Summary: Although this device is fast and potentially highly versatile it is riddled with problems, check the Qnap forum for details. Mine was faulty from day 1, first problem was that it would not switch off neither from software or hardware. Contrary to what the first poster states you can switch it off from hardware, just hold the power button in for a couple of seconds. At least that's the theory, mine would turn off ok but would immediately restart.
Summary: The NAS is OK. Hardware-wise, I would rate it at least 4 stars. Software support... it's another matter. Last february, I opened a ticket with QNAP support about some bugs in NTFS implementation. I also wrote a thread in QNAP forums about the issue. To cut the long story short, if you connect an external NTFS disk to NAS (via USB or eSata), after a while you lose access to files.
Summary: Es ist schnell, zumindest beim Datentransfer. Das ist das einzig Gute was ich von diesem Gerät berichten kann. Ansonsten ist der Lüfter so laut, dass er im Wohnzimmer deutlich stört. Dazu schwingt sich das klapperige Gehäuse noch ab und zu auf und dann wird es richtig laut. Man kann das bessern indem man den Lüfter mit Schwingungsentkoppelten Gummihalterungen ausstattet und zwischen Platte und Halterung Gummistücke einlegt.
Summary: Negativ: - Abwicklung in der Garantiezeit. - Zeitaufwand für die Schilderung des Problems. - Defekt nach Automatischen Qnap Firmwareupdate !!! Sollte man sich überlegen eine Qnap Nas anzuschaffen, muss man sich im vorhinein überlegen wie lange man auf das Gerät verzichten kann, falls ein Defekt vorliegt.
