There are so many software features that we could write an entire article just on the operating system and what's inside. In fact, we plan to publish comprehensive feature stories covering NAS operating systems and their GUIs in the future. For now, there are more native features and optional add-ons than we can introduce in a single device review.
There are hundreds of pages in the QNAP QTS operating system, but they all originate from the main screen. The icons are similar to what you find in Android; you can move and re-position them across the three default pages. Of course, you can also add and remove icons as needed.
The health check feature in the lower-right corner of the dashboard opens to what we see here. It provides a quick way to catch the latest QNAP software news, see details about firmware updates and view the system's status. You can monitor the storage array and CPU, in addition to keeping an eye on memory usage and network traffic. Another pane shows if other users are logged in to the system; you don't want to update firmware or restart the NAS if someone else is using a shared file from a remote location.
Before we even get into the applications, let's look at the system's many configurable features. Everything comes set up from QNAP to be completely usable. But you can easily change the options to create a more customized experience.
For instance, disable and hide all of the home/multimedia functions by clicking a single check-box. This helps save processing cycles and system memory if those capabilities aren't needed.
In QTS' Storage Manager, you can build arrays either in volumes or by pools of disks. The latter option, introduced a few years ago, allows the appliance to tackle storage like an enterprise-class SAN. For example, one part of a drive may be a member of a RAID 0 array, while another section is part of a RAID 5 array.
When we review QNAP NAS appliances, we use the single-volume option. Systems with seven drive bays and less are tested in RAID 5, while systems with eight or more disks are tested in RAID 6.
You get a lot of networking options, too. QNAP facilitates several modes of network teaming, including 802.11ad link aggregation. And there are a few ways to connect to the system from outside of your intranet: it's accessible from QNAP's cloud feature, a free service through a specialized website, or through a third-party DDNS service.
