Windows 10: USB 3.1 version 2 cables and performance Solved

    USB 3.1 version 2 cables and performance

    Will a USB 3.1 version 2 device run at maximum efficiency using a USB 3.0 cable? I have read that USB 3.0 and USB 3.1 version 1 can use the same cable but I can't find any information relating to USB 3.1 version 2.

    Also, will there be any performance increase with a standard SATA hard drive using USB 3.1 version 2 over USB 3.0? Is the SATA drive fast enough to take advantage of the of the new USB 3.1 version 2 speed?

    USB 3.1 gen 2 does have stricter cabling requirements than 3.0/3.1 gen 1. So you aren't guaranteed to get maximum gen 2 speed out of a gen 1 cable, though you may get lucky if the cable was manufactured well.

    Real-world throughput for gen 1 is around 400MBps and gen 2 is around 800MBps. A mechanical hard drive won't sustain anywhere near 400MBps. However, an SSD will likely saturate a gen 1 connection.
