Thunderbolt vs. USB-C: A Port Selection Guide to Expanding Laptop Functionality
Laptops used to have an abundance of ports to meet your needs for connecting a wide range of popular peripherals. However, as manufacturers pursue thinner and lighter designs, most laptops have eliminated multiple ports in favor of Thunderbolt and USB-C connectors.
For users who need to frequently connect accessories, a Thunderbolt dock is an ideal choice. It provides multiple input and output connections through a single cable while also charging the computer. Thunderbolt docks are designed to expand the functionality of laptops, allowing you to connect multiple peripherals (such as displays, drives, printers, etc.) to your computer through a single cable with just one Thunderbolt port.
When you're working at your desk, a Thunderbolt dock transforms your laptop into a makeshift desktop computer, giving you easy access to multiple peripherals without having to repeatedly plug and unplug. When you leave your desk, simply plug your devices into a power source; when you return, simply plug the Thunderbolt cable into your laptop to instantly connect all your devices.
Thunderbolt is perfect for creative professionals who need the fastest transfer speeds and the widest selection of ports. However, for most users, a more affordable USB-C hub is also a good choice. It uses the same connector to accomplish almost all of the same tasks, albeit with slower transfer speeds and fewer ports.
The standards and names of USB-C, USB4, and Thunderbolt can be confusing because they look very similar. However, each name actually refers to a different connection standard, each with its own advantages. Thunderbolt 3 and Thunderbolt 4 (which can be considered interchangeable) are enhanced versions of USB-C that offer faster transfer rates (up to 40 Gbps) and support bidirectional data transfer. This means it can connect a range of devices including hard drives over a single cable, while charging a laptop and outputting video.
Because Thunderbolt is more complex, it costs more for computer manufacturers to adopt it. As a result, it has mainly appeared on recent Macs and high-end Windows PCs. Thunderbolt 4 has the same maximum data transfer rate as Thunderbolt 3, but with higher minimum requirements for video and data.
USB4 (sometimes also stylized as USB 4), on the other hand, is being advertised on products such as Apple's M-series Mac laptops. It functions exactly the same as Thunderbolt 3, but it is a royalty-free standard established through the USB Implementers Forum, unlike Thunderbolt 3 which is owned and controlled by Intel.
When choosing a port to expand your laptop's capabilities, decide whether to go with Thunderbolt or USB-C based on your needs and budget.
