The product is class, not a question, but I had just installed Seagate desktop hard drives that do not allow 24/7 operation. Despite demand at Buffalo and Amazon should here WD Red HDD have been installed. Unfortunately, this was not the case. Therefore, an ice-cold one star rating, even if it does not fit many. Because to build in in a NAS on work desktop HDD's without 24/7 certification is already an impertinence. Especially when you individually to NAS and HDD's that you want to have yourself together also gets cheaper.
We are rated only Nas therefore full 5 stars because all the features that are important to me are supported. Reviewed you only the hard drives, what I do in the case because it is the 16TB version, there is only one star.
Installed were:
Seagate Desktop HDD.15 ST4000DM000
These are not designed for continuous operation. But a NAS is a device that uses one continuous operation!
