QNAP Systems Reviews 

Dreadful: I don't use my QNAP on a regular basis. The drives don't get hammered because nowadays I only use it as an ad-hoc data archive....so I really DO expect it to be reliable on the odd occasions I need to access it. Only since the ENFORCED firmware that occurred overnight last year (which completely changed my interface) I can only get as far as the root folder then it other denies me access to my data altogther or after 30 minutes, the rest of the directory structure springs back into life unaccountably. This is far worse than simply buying a USB backup drive. There is no way I'd ever use a QNAP as a server...not any more, 5 years ago maybe but in 2017, not a chance. QNAP techies spent 3 hours remotely fiddling with the server last year, then when they couldn't make any headway, decided that I had undertaken an inappropriate firmware update and therefore I was to blame for the mess. The firmware update had taken place automatically as soon as I switched it back on after a long period of disuse. I now which I had simply left it switched of.....or even better, thrown it in the bin. GARBAGE

I can only warn you to buy a product from this terrible company.
I made this mistake and it caused me serious trouble. I trusted about 6TB of data to my QNAP NAS (RAID 5). A few days later (my first full BackUp hadn't even finished yet) there was a Firmware-Update from QNAP. After the Firmware Update 4 out of the 6TB of data have just vanished! Hundredthousands of files are gone. Customer service didn't produce anything useful until now.
It's a real nightmare. Worst product experience ever!

Probably the worst electronic device ever purchased and it's not cheap. Customer service will blame anything apart from the product. The RAM for the device is a rip off over £100 for a 4gb module oh and apparently according to them no one elses ram will work.. Look else where if you need a reliable back up device, and do not even consider if you would like to stream multimedia as it just doesn't work.

Well it might for about 20 mins max before crashing.

We bought a small business TVS-EC880 , after 6 months the unit would randomly shut down. After many trouble shootings, we contacted the QNAP Support (Europe). They basically said, it was a software issue. We tried to solve it , without success. We believed it was a hardware issue. After trying another 3 months, QNAP also agreed that it was a hardware issue. Offer from QNAP: Ship it on our cost to the Netherlands, wait for a repair for an unknown time. Backup during that time ? Our problem.
Response time from the support on our email requests: Around one week. Unacceptable.
Will never buy QNAP again

QNAP TS453 PRO NAS failing in less than 2 Years!

I bought TS-453 PRO and in Less than 2 YEARS of Operations (and my receipt showing only few days more than 2 Years) the APPLIANCE Failed! Oh it is Out of Warrant! But worse, I offered to pay for the Service, but QNAP Cannot decide whether this is a Power Problem, Motherboard Problem, or other issue, and their local distributor Asked me to BUY ANOTHER NAS!?? SERIOUSLY? a High-End SMB Product, failing in less than 2 Years, and you can't even tell what is the Problem with the Appliance?!!? and Now you asked me to buy a new BAD QUALITY PRODUCT AGAIN?!

My Advise: NEVER BUY FROM QNAP Products again!

my Qnap ts 1079 pro has been failed second time ( I have 3 of these nas) it was faulty SATA interface controller and my RAID 5 failed not happy @ all as you can imagine
time to switch to other companies out there more reliable !!
Qnap (UK) asked me to send this faulty unit back to Holland with my own expenses !!! this is only 23 days old unit and with very high price tag
shame on you QNAP you should look after your customers
