    Customers are mixed about the ease of use of the system cabinet. Some mention that it's easy to set up and use, with clear instructions.

    Customers are mixed about the speed of the system cabinet. Some mention it's amazing, fast, and easy to use, while others say that it seems a bit slow at transferring data, not fast enough, and the network performance is poor. It's not inexpensive and a time drag as rebuilding can take a day or more. Customers also mention that the write performance is very poor and the transfer speed is 6.5GB per HOUR, which is unacceptable for a quick device.

    "...Anyway after getting the system set up I found the write performance to be very poor. Using AFP I was getting 34MBps using SMB I getting 44MBps...." Read more

    Customers are dissatisfied with the connectivity of the system cabinet. For example, they say it keeps dropping the network connection, it won't stay online for more than a couple of hours, and it has known issues with randomly dropping ethernet connections. That said, it goes missing from every point of connection and the drive would intermittently stop showing up on their network. It constantly has to be restarted and the drives had issue staying in standby.

    Customers are dissatisfied with the support provided by the system cabinet. They mention that there is zero support, poor support for third party cloud, and less supported cameras.

    "...avi (AVI container) is not supported by the Plex client (as it costs money for the license), nor is DTS passthrough, so the Media Server will try..." Read more

    "...Their drives either use Debian 7 (wheezy) or Busy Box. Poor support and you void your warranty by going to the shell (SSH) just to clear errors...." Read more

    "...known issues with randomly dropping ethernet connections and WD will not support it. I'm using it as an iSCSI target and it is horribly unstable...." Read more

    "No support. Great unit if you need a boat anchor!" Read more

    Customers are dissatisfied with the stability of the system cabinet. They mention that it's not powerful enough to transcode, has iffy hardware quality, and is not stable when it'd be on a network.

    "...on a EX4100 and dish out your media, but the one thing that it cannot do is transcoding...." Read more

    "...The EX4100 is not powerful enough to transcode, so you cannot play such files if using this device as the server...." Read more

    TOTAL SYSTEM FAILURE in less than two months of mild use.
    1 Star
    TOTAL SYSTEM FAILURE in less than two months of mild use.
    Worked fine backing up and storing our larger files, but all of sudden got a "System Under Temperature" error on ONE of the bays. Ok, so the other three bays have their own climate? Then, the red light of death for Drive/Bay 1. Fine. Restarted and put in a replacement drive. Nope still dead, and now look, bay/drive 2 is now dead. Day later, there goes bay/drive 4, so I quickly turned off and popped out drive #3 hoping to save it. Sadly #3 didn't make it either. All four (WD Red) drives have been killed by this monstrosity. And it was one month past the amazon return date, so now I get to pay to return it only to get a replacement (which I don't want or trust now) from WD.RUN AWAY from this horrible product at all costs if you want to keep you data.
    Thank you for your feedback
