QNAP TS-453B Reviewed: Powerful And Light


The TS-453B from QNAP is part of the TS-x53B Network Attached Storage (NAS) line up of storage devices, that comes in a new sleek look. It features an OLED panel and two responsive touch buttons.

Drive access is quick, easy and completely tool-less. This means that your drives will snap right in or out of the device whenever you need to replace them. No tools necessary.

With the dimensions at 168 x 170 x 226mm and the weight at just slightly over 2.33 kgs, TS-453B is the smallest in the series, which makes it perfect for small business and home use.


The new design features a sliding cover for faster and easier access to the drives located inside.

The OLED panel display system shows temperature, cooling fan speed, available storage space on your hard drives, your IP address and LUN.

Having all this information available at a glance gives you increased control and allows you to quickly check your system status, IP settings and the passwords for your host.

You can even shut the entire system down quickly using easy access buttons.

The front panel contains a SD card slot, which you can use to transfer data from your camera or phone directly to your TS-453B.

Below the SD slot there is a USB-C port, which lets you plug the NAS directly into your computer. By doing that, you can quickly gain access to all of your data using a USB-C cable (which comes included with the device.)

Right under the USB-C port, you’ll see a USB 3.0 port, which is accompanied by a very convenient, one touch copy button.

This button lets you quickly copy all your files from a flash drive directly onto the NAS (and yes, you do have the ability to easily configure where on the NAS your data gets saved.)

When you flip the device around and look at the back, you’ll see even more ports that come with your storage. There are two Gigabit LAN ports, two HDMI ports, four additional USB 3.0 ports and a PCI expansion slot.

The ports on the back are perfectly placed, and they’re a breeze to access and use. Also, the cables in the back are organized in such a way, that it is remarkably easy to keep them neatly organized.

The overall design of the TS-453B is compact and very easy to work with. When I first saw it, I was quite surprised by the tiny footprint it has.

This device will fit any office space, regardless of how big or small it is.

As mentioned before, TS-453B houses two tool-less drive slots that can take either 3.5” or 2.5” hard drives, including Solid State Drives for more speed and stability.

TS-453B also features a USB-C Quick Access port, which allows for first time installation and set-up without the requirement of network connectivity.

Files and data can also be directly accessed by using Qfinder Pro. Keep in mind, however, that Qfinder Pro is only supported by windows 8.0 or later and Mac OS X 10.7 or later.

The device is powered by quad core Intel Celeron J3455, 1.5GHz processor, and up to 8GB RAM. This simply means that all your tasks will be run smoothly and quickly with up to 225 MB/s of read – write speeds.

QNAP has chosen to implement a quad-core CPU and as a result, offering more than sufficient performance to satisfy even the pickiest users. The device is surprising quiet, due to a cooling fan being neatly housed, and muffled inside the machine.

The TS-453B was configured as follows:

  • RAM – 4GB
  • HDD #1 – Samsung 850 EVO 250GB SSD
  • HDD #2 – Samsung 850 EVO 250GB SSD

Hdparm was used to see how the unit performed with buffered and cached disk read speeds under RAID1:

# hdparm -Tt /dev/sda


 Timing cached reads:   8460 MB in  2.00 seconds = 4231.36 MB/sec
 Timing buffered disk reads:  1498 MB in  3.00 seconds = 498.95 MB/sec


When using TS-453B in a single client scenario, you’ll see that transfer speeds average at about 100-115MB/s for unencrypted data.

In a multiple client situation, increased demands are handled smoothly as well, the TS-453B didn’t even break a sweat. In our test with 4 clients, the TS-453B continued to perform well over a single gigabit link with our file transfer tests. The average read/write speeds hovering at about 101MB/s and 102MB/s respectively.

It remained cool and responsive through the entire test period, and at no time have we experienced any noticeable lags or other signs of distress.

Final Thoughts

TS-453B houses a tremendous amount of power for such a small frame, and the combination of Intel Celeron J3455 quad-core, DDR3L RAM, USB 3.0 and Gigabit Ethernet work extremely well together.

The OLED screen makes it easy for users to stay on top of what the unit is doing and how it’s performing.

Considering how reasonably this unit is priced, and the fact that it can easily handle two drives out of the box, with expansion options available for up to six drives, TS-453B offers fantastic value for the money.
