Upcoming USB 3.2 Specification Will Double Data Rates Using Existing Cables

A new USB specification has been introduced today by the USB 3.0 Promoter Group, which is comprised of Apple, HP, Intel, Microsoft, and other companies. The new USB 3.2 specification will replace the existing 3.1 specification and will double data rates to 20Gbps using new wires available if your device embraces the newest USB hardware. Mac Rumors reports: An incremental update, USB 3.2 is designed to define multi-lane operation for USB 3.2 hosts and devices. USB Type-C cables already support multi-lane operation, and with USB 3.2, hosts and devices can be created as multi-lane solutions, allowing for either two lanes of 5Gb/s or two lanes of 10Gb/s operation. With support for two lanes of 10Gb/s transfer speeds, performance is essentially doubled over existing USB-C cables. As an example, the USB Promoter Group says a USB 3.2 host connected to a USB 3.2 storage device will be capable of 2GB/sec data transfer performance over a USB-C cable certified for USB SuperSpeed 10Gb/s USB 3.1, while also remaining backwards compatible with earlier USB devices. Along with two-lane operation, USB 3.2 continues to use SuperSpeed USB layer data rates and encoding techniques and will introduce a minor update to hub specifications for seamless transitions between single and two-lane operation.
