QNAP TS-873 Review

The TS-873 8 Bay NAS is the latest from QNAP, and it sounds just like a perfectly promising device that will surely make waves this year. The company claims that the NAS offers premium high-performance, PCIe slot expansions, quad-core AMD RX 421-ND NAS, 10GbE network & graphics card support, M.2 SSD caching, 4K video & audio support, as well as high computing power.

QNAP notes that their TS-873 is packed with AMD’s latest high-end & quality R-series processors and it can also be increased to a total of 64 GB of DDR4 memory. If you plan to upgrade to the 10GbE by installing a 10G network card, the performance will reach up to 1,661 MB/s.

The TS-873 also features low power consumption, high-speed multitasking, as well as an AES-NI hardware encryption engine which claims to be one of the most cost-efficient AES 256-bit encrypted NAS device today.

Since it utilizes low-power, high-performing, and high-quality AMD R-series processors, this 8 Bay NAS device provides increased PCIe upgrades and scalability which is something that a lot of people would want. You’ll get to conveniently set up the QNAP QM2 M.2 SSD / 10GbE PCIe expansion card to include the M.2 to SSD cache, NAS, and 10GbE network connectivity.

The TS-873 probably has piqued your interest but maybe you’re thinking that this NAS device is a bit too good to be true? Today, we’re going to focus on this NAS device from QNAP and see if it’s just as awesome as the company claims it to be, and if it can really live up to its claims when it comes to performance.

First up, let’s take a look at what’s included inside the box of this device, and learn a bit more of this product from QNAP.

QNAP TS-873 Review – What’s in the Box?

The packaging of the TS-873 is a simple cardboard box, which is just like every other NAS device from QNAP. The box is a bit large and it doesn’t feature any fancy designs which is good since it gives off a clean and neat exterior. The only thing that’s colored on its packaging is a sticker in front.

On the sticker, you will find an image of the TS-873 NAS device itself. You will also see its name, as well as a list of its key features. Each side and on top of the box is clean and the only thing that you’ll see is the company’s logo.

Underneath the box, you will find more stickers that feature various barcodes, a sticker for the UPC Code, and under this is the EAN Code. Under the EAN Code is a larger sticker with five barcodes.

Inside the box is the NAS itself. Just like all of QNAP’s products, there are also pieces of Styrofoam around the TS-873. This is to keep the device protected while in transit. You will also find another smaller box that contains two Ethernet cables, screws for installing the drives & M.2 SSDs, a quick installation guide, and warranty information.

Using the Product

Of course, we didn’t pass up on trying out the TS-873 NAS device, and we do have the model that has 4GB of RAM. The first thing that we can say about this device is that it’s a great product that works really well. We used it as a NAS, for virtualization, and as a Plex media server.

We loved the fact that QNAP continues to develop and enhance their firmware, so features like snapshot backups, backups, and more, continue to improve. Another element that we appreciate about this TS-873 is the fact that we were able to dedicate an SSD to virtualization.

It is extremely quiet during operations and that’s really a good thing especially if you’re someone who’s really concerned about devices being noisy when used. Also, this is probably the most full-featured NAS device that we’ve ever tried; plus, it’s really great as a file server for small businesses and of course, for home use.

Just recently, we decided to install a Plex server on our TS-873 8 Bay NAS. We installed this as a QPKG the pointed it directly to our movie. Plex instantly took the name of all our movies then searched for each of their posters; some of them were wrong but could be corrected manually. Playback was seamless and skipping through chapters was relatively swift.

Overall, we’re quite impressed with how fast the QNAP TS-873 8 Bay NAS when it comes to transferring data. And if you compare its performance with the older models of NAS, you’ll surely love its improvements and enhancements. Because of its excellent performance, efficiency, and upgrades, we’re definitely going to recommend this to anyone and everyone who plans to upgrade their current NAS devices.

The QVR Pro: A Brand New Surveillance Solution

Sometime in the past, surveillance apps were simply one of the numerous applications available on the NAS. It didn’t have any specific storage for surveillance recordings, and its system performance was often limited. This made it inadequate for achieving the requirements of qualified surveillance systems.

QNAP’s latest surveillance application, the QVR Pro, presents the idea of dedicated storage space. This is to guarantee that your storage will be completely restricted for the QVR Pro, while its system performance won’t be affected by other applications that are available on the NAS.

This new solution from QNAP allows you to organize an independent and dedicated storage space for all the surveillance data located on the TS-873. You can also leverage its benefits of storage management and scalability from the QTS.

With the QVR Pro, things like storage space allocation, camera management, live camera viewing, as well as playback have been readily simplified for ease of use. Not only that, but you can also utilize the QVR Pro Client mobile application to better monitor your cameras anywhere; if not, you can use your USB webcam and turn it into an ONVIF network camera using the QUSB Cam 2 app.

With this, you’ll get to conveniently manage and monitor a number of IP cameras in real-time using web browsers, while having a first-hand status of monitored areas. You’ll be able to manage your fisheye and PTZ cameras while flexibly monitoring each area of choice with detail. With its user defined views and default display mode, you’ll be able to effortlessly manage your surveillance system.

The QVR Pro backs a ton of camera models today, and these are from more than 140 brands with numerous image formats. It lets you seamlessly create a variety of surveillance solutions that cater to your choice and suits your environment while also giving you convenient camera control.

In the Device Pairing and Service Account portion, you’ll find four kinds of notification delivery options: these include SMS (Twili, Nexmo, and more), email (Gmail, Yahoo, Outlook, etc.), instant messaging, as well as push notifications.  You can select a specific procedure as required, or utilize a variety of methods to guarantee that you always get updated and notified.


We don’t really keep our hopes up at first until we’ve tried out the products that we have, but when it comes to this TS-873 8 Bay NAS from QNAP, it surely exceeded our expectations. At first, we were reluctant to believe that this NAS device could work as effectively and efficiently as QNAP claims it to be, but after trying it out and testing it for almost a week, we can definitely say that you can’t go wrong with QNAP’s devices.

At first, we assumed that a lot of command line functions were necessary, just to reach some of the advanced features that are present on the NAS. Surprisingly, the TS-873 is also extremely easy to manage and setup, meaning, you don’t need to have any technical expertise to get this thing moving.

It’s far easier than expected so you don’t really have to worry about setting up the NAS device. Switching features off and on via the web portal interface was extremely easy, and the QNAP TS-873 is powerful enough to adequately run the Plex server to play media on a PC, as well as to simultaneously perform file server functions.

Not only that, but the TS-873 is also very responsive over the Gigabit single-port when copying big media files and backups. We decided to setup the TS-873 8 Bay NAS in our office’s basement and we were still able to add this to the media center and easily play media from it without worries.  Just keep in mind that you will need to purchase your own drives for the TS-873; factor in a total of eight hard drives in addition to the expense that you’ll have for this device.

Lastly, the device consumes less than a quarter of electricity compared to our previous devices but it still works faster; so basically, this is a really nicely-made device that functions excellently. So we’re giving the QNAP TS-873 8 Bay NAS device two thumbs up for its great performance, sturdy build, and efficiency.
