What To Look For In The Best Thunderbolt 3 Dock

There are tons of reasons why you would need to connect multiple components and pieces of hardware to your computer. Not the least of which are gaming, surveillance systems, business applications, and engineering projects. Those are just a few examples. Most computers don’t have all of the ports you’ll need to connect all the parts you’d like. That’s where a Thunderbolt 3 dock comes in. This is a docking station that allows you to, essentially, add ports to your computer by connecting an external connection box to it with just one cable.

What should you look for in the best Thunderbolt 3 dock? For starters, you’ll look for a good data transfer rate, at least 40Gbps. The other three important factors are the ports, the cables, and the peripherals. You may only want a few kinds of ports or you’ll look for the whole gamut of connections. Also, consider the cables you’ll need. Look into what comes with the docking station and pay attention to the length of them. In terms of peripherals, you want to look for something that will accommodate all the peripheral items you intend to use with your computer.

Thunderbolt 3 docks can come in handy for both desktop and laptop computers. You want to choose one that fits your needs the best, though. So, let’s talk more about how you do that.

Do I Need A Thunderbolt 3 Dock?

You may not be sure if you need a Thunderbolt 3 docking station. If you’re working from home on a laptop that sits on a desk, a Thunderbolt 3 docking station will give you convenience and more flexibility with regards to port options. 

Some laptops, such as the MacBook Pro and the MacBook Air, have only a few USB-C ports to use with them. Thunderbolt 3 docks make it where you don’t have to figure out how you’re going to connect the peripherals you’d like to use with your computer. 

You’ll have to make sure your laptop is Thunderbolt 3 port enabled, but chances are, if you have a fairly recent laptop model that has the USB-C ports, they are compatible with a Thunderbolt 3 docking station.

What Are The Important Features Of The Best Thunderbolt 3 Docks?

You don’t want the data transfer speed to be too slow going through the docking station. When you’re using Thunderbolt 3 docks, you’re adding a bunch of options for inputs and outputs. That means you want the data to be able to travel from the peripheral you’re connecting to your computer, through the docking station, and into the Thunderbolt 3 port on your laptop without slowing down too much. Generally, you’ll find the new generation of Thunderbolt 3 docks to have a data transfer rate of 40Gbps.

You shouldn’t go with anything lower than that because it will cause hiccups that ultimately lead to frustration for you dealing with lagging. You’ll be able to get up to 10Gbps for USB speeds and have the ability to connect two 4K monitors, rather than just one. 

Obviously, the ports included on the docking station you choose are important. You can get one that is very basic and only carries some HDMI ports so you can connect two 4K displays. Alternatively, you can choose a Thunderbolt 3 port docking station that has the HDMI ports, an SD card slot, several USB ports, multiple Thunderbolt connections, an ethernet port, and more in some cases. Multiple Thunderbolt connection ports allow you to piggyback another docking station for even more connection options.

The cables you’ll need are often overlooked by those looking for the best Thunderbolt 3 docking station. The Thunderbolt 3 port box you choose should come with a Thunderbolt cable, at a minimum. Some Thunderbolts will only have one DisplayPort and one HDMI port. If you’re planning to connect two 4K monitors to your docking station, you’ll have to either have one that has two of each connection or you’ll have to get a braided DisplayPort cable to tether the two displays together before connecting them to the docking station.

Length is also very important when it comes to considering cables. You should pay special attention to how long the Thunderbolt cable is that will connect the laptop to the Thunderbolt 3 port box. Also, the cable that will tether the two displays, if you’re going with that option, has to be long enough for your preferred positioning of the monitors. It’s best if you have your placement configuration decided on before obtaining any cables so you know how long they need to be. 

Try to think of all the possible peripherals you’ll want to connect to your laptop. The best Thunderbolt will accommodate your displays, mice you intend to use, any keyboards, graphics cards, SD cards, speakers, you name it.
