If you’re the kind of person who copies hundreds of photos or giant video files onto your external hard drive, know that there’s good news: the USB ports are about to double speed again. The USB Implementers Forum 3.0, which includes Apple, HP, Intel, Microsoft and other companies, released a cable specification yesterday, which is called USB 3.2 and will replace the current USB 3.1.
An incremental upgrade to USB 3.2 is designed to define multi-way operation for USB 3.2 devices. USB Type C cables already support multi-way operation, and with USB 3.2, hosts and devices can be created as multi-way solutions, allowing two 5 GB per second or two 10 GB per second ways. With support for two 10GB per second transfer rates, performance is essentially doubled over existing USB-C cables . A faster USB is useful if you are restoring data from a drive, backing up your music collection or transferring video. In the future the USB-C could also be used to connect monitors.
To take advantage of USB 3.2 you will need devices that support it . That said, assuming that both host and receiver devices are USB 3.2 compliant, even older USB 3.0 cables will work at faster speeds of up to 2 GB per second. Therefore, assuming the manufacturers support it, there will be some advantages in adapting the new specification, even if you cannot yet upgrade .
Along with two-way operation, USB 3.2 continues to use SuperSpeed USB data rates and encoding techniques, and will introduce a small update to the hub specifications for seamless transitions between single channel and two-way operation .
We will learn more about this in Vancouver, Canada next September 26th, within the USB developers conference .
