At the office, home or school, USB-C has arrived. We’ve got tips on how to take advantage of those new ports, along with a peek at the future of data transfer and video.

You’ve probably noticed something strange about many of the latest phones, tablets and laptops at your company: The familiar rectangular Type-A USB ports are gone, replaced by smaller oblong connectors. USB-C has taken over at work, at home and at school.

While many iPhone and iPad models stick with Apple’s proprietary Lightning connector, USB-C is now part and parcel of most laptops, phones and tablets made today. Even the latest MacBooks and Chromebooks are part of the movement to USB-C.

What is USB-C?

USB Type-C, usually referred to as just USB-C, is a relatively new connector for delivering data and power to and from computing devices. Because the USB-C plug is symmetrical, it can be inserted either way, eliminating the frustrations of earlier USB ports and putting it on a par with Apple’s reversible Lightning plug.

 

This alone makes it a hit for me, but USB-C is closely linked to several powerful new technologies, including Thunderbolt and USB Power Delivery, that can change how we think about our gear and working in the office, on the road or at home.

Most USB-C ports are built on the second-generation USB 3.1 data-transfer standard, which can theoretically deliver data at speeds of up to 10Gbps — twice as fast as USB 3.0 and first-gen USB 3.1, which both top out at 5Gbps. The key is to get devices that say “USB 3.1 Rev 2,” “USB 3.1 Gen 2,” “SuperSpeed USB 10Gbps,” or “SuperSpeed+” to get support for the faster spec.

Confusing matters more, the current USB 3.2 standard is mostly a restatement of USB 3.1 specs. For instance, USB 3.2 Gen 1 and 2 are the same as USB 3.1 Gen 1 and 2. The new spec that’s actually noteworthy is USB 3.2 Gen 2X2, which has a pair of 10Gbps lanes of data traffic available for a total of 20Gbps. So far, however, it hasn’t caught on with device manufacturers, so it’s hard to find it on any devices in the wild. That might change in the coming year as new controller chips come out.

To make sure the data gets through at higher speeds, always get high-quality cables. They will often have the SuperSpeed logo and a “10” on them to show they’re capable of moving 10Gbps. The good news is that there’s a good chance that this spaghetti bowl of cable standards could disappear with the next rev of the USB spec with a universal USB cable. More on that later.
