Look out for device charging potential, too, with up to 7.5W on offer with some docks and hubs. Many of the models tested here include faster 10GBps USB-A.
USB-A (the old rectangular connector that had to go in one way, usually not the first way you tried) usually maxed at a bandwidth of 5Gbps (USB 3.0) but could be as slow as 480MBps (USB 2.0). They supersede older USB 3.0/USB-A connectors and also slower USB-C variants in terms of speed, but are backwards compatible with USB-C and Thunderbolt 3. Learn more about the differences between USB-C, USB4, Thunderbolt 3 and Thunderbolt 4. The latest connection standards are Thunderbolt 4 and USB4, which are both based on the neat reversible USB-C connector seen on most new computing devices. They are also the best way to add an external display or two to your more mobile computer, plus Gigabit (or faster) Ethernet for wired Internet access.Īll the docks and hubs tested here support two external 4K displays at 60Hz a single 8K display (Windows) or a single 6K display (Mac). You will therefore need to connect a multifunction adapter, hub or a more able docking station that includes the ports and slots you need to add extra devices such as hard drives, memory sticks, storage-card readers, printers and so on, as well as wired input tools such as a keyboard or mouse. Hubs and docks allow you to add more types of connections to your main computer if it lacks them itself-particularly with laptops that might have just a few ports on the side.ĭesktop PCs and Macs usually have a decent set of ports at front and back, but laptops and tablets often have just a couple. They take over from Thunderbolt 3 and USB-C hubs and docks, with significant future-proof benefits while staying backwards compatible with the older connectivity standards. Thunderbolt 4 and USB4 hubs and docks are the latest technologies in computer connectivity and expansion.
