“SuperSpeed” USB 3.0 offers 4.8 Gbits/s
One example of their speed goals is to transfer a 27GB HD movie to a portable device in 70 seconds. The same thing would take 15 minutes or more with HighSpeed USB (2.0). The SuperSpeed devices will use the same connectors and the same programming and device models as existing devices. Consider that it takes maybe one or two tenths of a second to transfer a typical 4 Mbyte song to a portable music player with today’s USB 2.0. That’s “fast enough” for some users, but just try to fill up that 80-Gbyte iPod and you might as well walk away and cook dinner while you wait: 3,000 songs would take perhaps 400 to 600 seconds ? up to 10 minutes.
