Just When You Got Used To USB-C, It’s On To USB4

Anything with electronics inside to subject to an arms race when it comes to a way to interface with it. There was a collective groan from computer users everywhere when USB-C was introduced, not because of its considerable features, but because the plug was different. That meant that hard drives, interfaces, monitors and more were in need of an upgrade (unless you were already using Thunderbolt 3, which used the same connector) once more. Well, get ready for yet another data interface upgrade, this time to USB4.

USB4 should be a lot less painful than the update to USB-C. That’s because the same connector is being used. It does have improved performance though, that makes it valuable. Here’s what to expect.

  • up to 40Gbps operation over 40Gbps certified cables (about double the normal speed normally seen today over USB-3.2)
  • juggle a lot of different data streams
  • Incorporates Thunderbolt 3 technology
  • Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3
  • deliver power to outboard devices (which USB-C does today as well)

Here’s the best part though. USB4 will allow for dongles that incorporate multiple ports, just like the old USB multi-port dongles of the past. USB-C and Thunderbolt multi-port dongles are pretty much non-existent because of the costs involved. This means that the aftermarket USB4 accessory market should be more robust and cheaper too.

Essentially USB4 promises to eliminate the multiple data interfaces that have plagued us for so long. No more USB and Firewire, USB and USB-C, USB and Thunderbolt, or USB ports with different speeds on the same device. USB4 means that one port will fit all.

It’s not going to be here tomorrow though. You should expect to see devices incorporating USB4 probably about a year from now. It can’t come fast enough if you ask me.
