QNAP TVS-672N Reviewed


Representing an evolution of their lineup of Network Attached Storage (NAS) solutions, the QNAP TVS-x72N features some pretty exciting hardware improvements. We were able to get our hands on the TVS-672N for a quick test drive.

Featured Technologies

QNAP has been pushing for faster speeds in their NAS line up for some time now. Most, if not all, of their top-end SOHO to enterprise models already support 10Gbps. Showing some love for the entry-level SOHO models, QNAP now includes a 4-speed 5GBASE-T (5Gbps/2.5Gbps/1Gbps/100mbps) NIC. The 5Gbps connection is going to make 4K video and file sharing across your network buttery smooth.

Another significant advantage of the QNAP TVS-672N has to be the fact that it comes with two separate M.2 PCIe (Gen 3 x2, 2 GB/s) NVMe SSD slots. NVMe SSD opens up lightning-fast SSD cashing capabilities, complete with HBS three technology that includes data de-duplication setups. You will be able to breeze through data backup and recovery a lot faster no matter how you have your RAID settings established with this technology.

We were hoping to use an existing Seagate Firecuda (Gen 3 x4) NVMe SSD, but unfortunately, x4 devices are not supported. Always check the QNAP Compatability List before you go ahead and purchase 3rd party components for your NAS.

We were looking forward to using the Firecuda but alas no support for this x4 module

Supporting the latest Wi-Fi 6 Trends

Modern setups using the latest wireless routers are now supporting Wi-Fi 6 (802.11ax). This means that wireless bandwidth is capable of reaching 5Gbps under optimal conditions with ease. Older NAS devices in your network will not be able to keep up as most run on legacy 1Gbps or slower network connections. Couple the QNAP TVS-672N with the QNAP USB 3.0 to 5GbE adapter (QNA-UC5G1T) and you’ve got 5Gpbs all around. Whether you are on Wi-Fi 6 or networked (using the adapter), you will have plenty of speed to cater for most common tasks.

The following reference image from the QNAP site does a great job of explaining this:

Chassis Design

The QNAP TVS-672N itself also looks quite similar to its predecessor models. It’s a design that’s worked well for QNAP so doesn’t need to change.

We reviewed the six-bay model, but there is also an eight-bay model available. In addition to being able to house six 3.5″/2.5″ drives, you can also install two M.2 SSDs internally. As I mentioned earlier, ensure you use compatible units.

Streaming Features

Setting up your private cloud is a significant benefit of using a NAS. Similarly, more and more people are choosing to use NAS technology like the QNAP TVS-672N to create their media servers as well.

The QNAP TVS-672N includes an Intel integrated UHD Graphics 630 card. The 630 is capable of triple channel 4K H.264 hardware decoding as well as real-time transcoding of multimedia up to 4K resolutions. Also, HDMI 2.0 outputs allow you to keep this NAS close to your main screen (TV, monitor, projector, etc.). You also have the opportunity to stream the content as well – even beyond your internal network.


The eighth-generation Intel Core i3 processors act as the brains of the new QNAP TVS-672N NAS. They provide the right level of processing power without chewing up a lot of energy or producing a lot of heat.

Our storage drives for the QNAPs are always the Seagates. We did some localised hdparm benching with a couple of the 14TB IronWolf drives.

Closing Thoughts

The QNAP TVS-672N is a notable step forward compared to previous models. The TVS-672 sits squarely between the consumer and enterprise markets. It’s difficult to pigeonhole everything the QNAP TVS-672N offers. But that’s part of its attractiveness and allure.

There are a lot of impressive features about the QNAP TVS-672N. The NAS is affordable, easy to set up and features next-generation technology. These all help to set it apart from the rest of the pack.
