How Fast Is USB 3.0 Really?
While you won’t see a tenfold increase in the transfer speed from USB 2.0 to USB 3.0 in real-world use, USB 3.0 is fast—about three times faster than USB 2.0 with a spinning hard drive, and three to five times faster with SSD. And using a hub doesn’t impact speeds, even with other (and slower) peripherals attached. USB 3.0 is also faster than FireWire 800, and it stacks up favorably against Thunderbolt.
