SuperSpeed USB 3.0: More Details Emerge

Performance improvements are notable, too. "We have research that shows that after 1 minute, 1.5 minutes waiting for a transaction, users get impatient.," says Ravencraft. "The transfer times have to get much faster." Hence the evolution of USB SuperSpeed's Sync & Go concept.

SuperSpeed USB 3.0's 5Gbps data rate (compared with Hi-Speed USB 2.0's 480Mbps) should help--and with very clear real-world advantages. For example: A 25GB HD movie will take 13.9 min to transfer with USB 2.0, and 70 seconds with USB 3.0, says Ravencraft.
