Though ourpersonal computing deviceshave gotten smaller and more powerful over the years, the number ofUSB,Thunderbolt, and other types of ports present on these devices has decreased. And no matter if your device has one, two, or three USB-C or Thunderbolt ports, the fact of the matter is you can always use more—especially if you depend on external devices such ashard drivesand adapters to get your work done.
And that’s where docks and hubs come in. Both docks and hubs have risen in popularity and necessity alongside the rise of USB-C and Thunderbolt. Some of this is due to the lack of ports we mentioned earlier, but some of it is also due to how powerful and versatile these ports are due to their fast data transfer speeds and their ability to pass through power and display signals to your main device.
Unfortunately, “dock" and “hub" are sometimes used interchangeably to describe devices that add and enable these connections, but there are some differences between the two. Here’s what you need to know.
Thunderbolt 3/4 vs. USB-C
Before we can address hubs and docks, let’s talk about the protocol and cable specification behind these devices because this is the first place where a lot of confusion around device connectivity starts.
Thunderbolt 3/4 is a protocol and USB-C is a type of connector and cable specification. Thunderbolt isIntel’s trademarked name given to a high-speed protocol that can deliver power and adjust data and video bandwidth on-the-fly depending on its use. While Thunderbolt 1 and 2 used the Mini DisplayPort form factor Thunderbolt 3 and 4 use the USB-C port.
In other words, USB-C refers to the connector (port) and cable specification, whereas Thunderbolt 3/4 refers to thecapabilitiesthat are available over that USB-C connection.
Power supply
The first big difference when it comes to docks and hubs is thatThunderbolt 4 docking stationssupply more power than hubs. Among other features, this can add to the cost. That is why dynamic power in a docking station is important. This allows docks to supply additional power to your computer, but only when it’s needed.

It also allows the power supply on some docks to be smaller than those on others. And unless you’re running a half-dozen or more bus-powered devices at once that are connected to your dock, you won’t see any power drain on your computer.

Multiple “hubbing" and consistent speeds
One of the long-anticipated features brought along by Thunderbolt 4 is the ability to add multiple Thunderbolt devices to one dock, creating up to three independent chains. This is new to the Thunderbolt spec because Thunderbolt 3 didn’t allow for this and it allows docks to act as a parent device for hubs, but not the other way around.
But perhaps the most important improvement with Thunderbolt 4 is the fact that now both MacsandPCs have consistent and standardized speeds. Thunderbolt 3 and Thunderbolt 4 on the Mac provide 40Gb/s (which means that aside from the hubbing capabilities mentioned above, Mac users won’t see any performance difference between Thunderbolt 3 and Thunderbolt 4). Prior to Thunderbolt 4, if a PC user connected a Thunderbolt 3 device, throughput speeds could vary between 20 and 40Gb/s. Now, all Thunderbolt 4 users can enjoy the same speeds.
What it all comes down to
At the end of the day, when you’re in the market for a device that allows you to connect multiple other devices to your computer, you not only have to determine between Thunderbolt and USB-C, but you have to decide between a dock vs a hub. Let me make it easy for you:
If you need to simply expand the number of available Thunderbolt ports for external drives or other devices, you can do fine with a hub.
But if you need something with more gusto, can provide more power, and has lots of different connection options like headphones, SD card readers, and USB-A ports, go for a docking station.
No matter which you choose, you’ll be able to get more out of your devices and you’ll waste a lot less time searching for dongles or adapters.
