The existing USB 3.1 can transfer data at up to 10 gigabits per second using two lanes (5Gbps per lane), but the new USB 3.2 tech aims to double that to 20Gbps, or 2GB/sec, by allowing for 10Gbps per lane.
However, the devices you’re using will have to support the newest USB hardware and come with the modern USB-C connectors.
USB-C has long been touted as the universal standard that will save us all, a single port that can charge your phone, your laptop, your tablet, your Bluetooth speaker, and even your Nintendo console, all through a single common port.
With that in mind, the USB 3.0 Promoter Group — which counts Apple, HP, Intel, Microsoft, Texas Instruments, and others among its members — just announced another USB-C specification: USB 3.2. It will support “multi-lane operation” that, in theory, will allow devices utilizing it to transfer multiple lanes of data at the same time. Put simply: it’s faster than regular USB 3.0, allowing up to two lanes of 5Gbps or two lanes of 10Gbps operation.
Another benefit of USB 3.2 is that it will work with USB 3.0 and earlier devices, and requires only a minor hub update to “assure seamless transitions between single and two-lane operation.”
And that, for now, is all you need to know. The USB 3.2 specification is now in a final draft review phase, but the formal release is planned to go ahead in time for the USB Developer Days North America event in September.
Hope This Helps!
