[5] USB 3.0 connectors are generally backward compatible, but include new wiring and full-duplex operation. SuperSpeed+ (SS+) rate of 10 Gbit/s is defined by USB 3.1, and 20 Gbit/s using 2 lanes ...
The physical phenomena on which the device relies (such as spinning platters in a hard drive) will also impose limits; for instance, no spinning platter shipping in 2009 saturates SATA revision 2.0 (3 Gbit/s), so moving from this 3 Gbit/s interface to USB 3.0 at 4.8 Gbit/s for one spinning drive will result in no increase in realized transfer rate.
