The next generation of USB devices might support data transfer speeds as high as 80 Gbps, which would be twice as fast as current-gen Thunderbolt 4 products. From a report: The USB Promotor Group says it plans to publish the new USB4 version 2.0 specification ahead of this year’s USB Developer Days events scheduled for November, but it could take a few years before new cables, hubs, PCs, and mobile devices featuring the new technology are available for purchase. According to the group, the new protocol will make use of the same USB Type-C cables and connectors as USB4 version 1.0. In fact, if you’ve already got a USB Type-C passive cable that’s capable of 40 Gbps speeds, you should be able to use that same cable with next-gen hardware to achieve speeds up to 80 Gbps. But the new standard will also introduce a new USB Type-C active cable designed specifically for speeds up to 80 Gbps. The new standard is also backward compatible, which means that if you buy a new device with USB 4 v2 support, it will still work with older hardware featuring USB 2.0, 3.2, or Thunderbolt 3 connectivity. You just won’t be able to take advantage of the full speeds.
