There are better NAS units from qnap, look at them first and be aware of limitations.

  • Summary: I ended up returning this unit for several reasons. It did not support virtualization and the eSATA support is limited to non-raid configuration, which pooched using an existing esata tower I already had.

Working very well now

Joyce V., Newegg
20 October 2014
  • Summary: 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.
  • 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 ...
  • 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.

Random Reboots Copying Large Files Follow Up #01

Joyce V., Newegg
17 October 2014
  • 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 req...
  • Cons: With every random reboot it has to resync taking several hours. I surely hope this is the last one.

Random Reboots Copying Large Files

Joyce V., Newegg
16 October 2014
  • Summary: 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.
  • 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 i...

questionable pt 2

steven r., Newegg
23 July 2014
  • 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 hard...
  • 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.
