A:Answer Jerry, please look closer at the specifications: it says speeds up to 10 Gbps, which translates to gigaBITs per second. Not gigaBYTEs, which would be GBps.
Which makes its maximum transfer speed around 1250 megabytes per second, or just 1.25 GBps.
Seeing as this is also referring to the new USB 3.1 standard, your results will vary if you don't have a USB 3.1 compliant port.
