New USB 3.2 technology doubles data transfer to 20Gbps; but you have to wait until 2019
USB, the port that every phone and PC uses to transfer data, tops out today at 10 gigabits per second with USB 3.1.
The USB 3.0 Promoter Group — which counts Apple, HP, Intel, Microsoft, Texas Instruments, and others among its members — announced Tuesday a new USB-C specification: USB 3.2.
The new specification will support “multi-lane operation” that, in theory, will allow devices utilizing it to transfer multiple lanes of data at the same time.
It’s faster than regular USB 3.0, allowing up to two lanes of 5Gbps or two lanes of 10Gbps operation.
According to CNet, the new USB 3.2 technology doubles data transfer to 20Gbps using new wires available if your device embraces the newest USB hardware — specifically the modern USB-C connectors and cables.
But the industry group that announced the move Tuesday, the USB Implementers Forum, isn’t willing to commit to 20Gbps just yet, reports CNet.
It’ll be at least 12 to 18 months before the very first products hit the market, said USB-IF Chairman Brad Saunders.
The existing certified USB-C cables will work fine with new standard, according to CNet.
This year should be the tipping point for USB-C, according to analyst firm ABI Research. The number of devices shipping with USB-C should increase 69% each year through 2021, ABI said.
