4 out of 5 eggsWorking very well now

Pros: The support team identified the problem as a bad firmware update and walked me through how to reapply it. I can verify this was the issue since some things was missing that are there now even though the firmware version said the same number. From that point, the unit has been running solid and I have been backing up 27 desktops and 12 laptops and 3 servers every night without a problem.

Cons: should put some kind of crc checksum while doing the firmware update. The user can never tell if things don't get applied completely.

Other Thoughts: Because of the bad firmware update, this almost got RMA. Fortunately the support team was on to of it and narrowed it down within a day of my call.

3 out of 5 eggsRandom Reboots Copying Large Files Follow Up #01

Pros: +1 For the tech support. Better then average that's for sure.
"according the log we found this seems nas firmware incomplete, please try steps bellow to update again" etc, etc.

We have been back and forth in emails and will try the backup again once the raid is finished syncing.
I had already requested a RMA, but will hold off a bit longer to see if this does the trick :)

Cons: With every random reboot it has to resync taking several hours. I surely hope this is the last one.

3 out of 5 eggsRandom Reboots Copying Large Files

Pros: The amount of features this unit has is endless. I am very impressed with features of the unit.

Cons: I use Acronis Server backup and have had multiple random crashes while creating the large backup files. Usually anywhere from 8 gb to 40gb on the average. Tech support logged in and shutdown just about every service since I only need to to do backups to shared folder. No less then an hour later it's rebooting again. Back on the phone with tech support again. They poked around and couldn't find anything wrong. Made a diagnostic file to send the the support team to try and figure it out. Each drive is brand new WD 3TB RED and has been tested previously to install of bad sectors. Of course the firmware has been updated already.
Basically at this point they want a couple days to look at the diagnostic file. Originally they wanted me to remove the drives and let it sit for a couple days to see if it reboots.
I have 27 desktops and 14 laptops and 2 servers that need backing up daily and can't afford that kind of downtime. It's a shame I am going to have to RMA this device and will probably shoot for a different Manufacturer altogether rather then take the chance of getting another unreliable unit.

Other Thoughts: This would have gotten a 5 if not for the reliability. My 8TB WDSharespace from 2007 works better then this thing has in 4 days time.

3 out of 5 eggsquestionable pt 2

Pros: Seems that the failure of the networking on my last set was due to the first NAS 1/2 formatting the drives partially before it claimed a bay was bad. Seems I need to start it with all drives out of device, let it attach to network then reinitiallize everything. Fun Fun. Bright side, it isn't hardware failures for both NAS's, just a failure to properly attach to network (and constant rebooting) if the drives are not right.

Cons: No manual with the device to tell me such wonderful setup problems, requires a call to QNAp, who actually have fairly good hours and polite assistance.

1 out of 5 eggsQuestionable

Pros: Reasonable price for what it says it can do.

Cons: Well....I bought 2, neither worked. One kept swearing bay 4 drive was bad, even when I shuffled drives, still bay 4 bad. Also, one ethernet port refused to connect. The other, both ethernet ports refused to connect.

I have sent both back on an RMA, so that's another $40 I have spent for them. If the replacement pair is just as bad, well, at least I will have only spent $80 on junk and can then maybe buy a NAS that works.

Time will tell, maybe next set will be perfect and those 2 were flukes...

5 out of 5 eggsVery nice

Pros: Great personal storage solution. It has met everything I needed. Very easy to setup. After setup I have not seen any issues with speed. The interface is very easy to use. The extra apps are mostly useless, but I'm sure there are some people that they will use them. I tried the plex app, but it won't do any transcoding when installed directly on the qnap. Makes sense as there is just not enough processor and memory. Overall very happy with this device.

Cons: Not much. I did set it up with 4 3TB WD red drives in a raid 10. It took more than 24 hours to get the array fully online. That seemed a bit long to me.

Other Thoughts: Great storage device for home use.
