|Over 100 official and community software add-ons such as Photo Station, Music Station, Video Station, DLNA server, Notes Station, Signage Station, Airplay/Chromecast, and more
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.

Bought a QNAP just over a month ago. Didn't find one sporting hardware from AMD, and I didn't think it would come anytime soon. Good to see that it actually performs well and isn't just the good old "cheap and slow AMD stuff". Will still be a while before I buy a new NAS though, sorry AMD. I do try to support you from time to time.Reply
With such a powerful SOC, can it do Movie transcoding to DLNA?? So i can easily watch things on my TV via wifi?Reply
Maybe I missed it, but I don't see test setup info on how you are fairly comparing 4-bay and 5-bay devices? For instance, QNAPs own 453 vs 563.Reply
If just a memory is different between $542 to $709 seems so much difference. There should be some other features missing on the cheap one.Reply
Four, five and six bay NAS are all tested in RAID 5 and with a single gigabit connection back to the network. Those systems are all grouped together and it's easy to spot overlap in the pricing as well.Reply
The only difference is the memory.
I think 8GB model comes with more camera license or different RAID configurations or something else. Because 2x4GB SO-DIMM memory doesn't make that much difference.Reply
I thought we would see power consumption comparisons, or did I just missed it?Reply
If these things always use cheap SOC's and opensource software, why are they are always so much more expensive than a PC I could build that would many times faster for less. I would love a NAS, but until they are more reasonable priced, I will stick with cheaper PC's that can do more and are faster. $700 will buy you a monster CPU, way more RAM than 8GB, etc. Ya, no hot swap case, but whatever. How often do you have to swap out dead drives.Reply
So what you are asking for is a free operating system, software plugins, optimizations, fast / redundant file systems and so on for little to no cost?Reply
They are not just about the hardware and support.
He has a point though. The price is high, and for people who like to tinker with old machines/cases they can build a NAS/server for their own office on the cheap that could be significantly more powerful from leftover components. These things are all running some variant of linux anyways, so don't even get us started on that.Reply
