USB 3.0, also known as SuperSpeed USB, will increase the speed from 480MB/s (USB 2.0) to 5GB/s. USB 3.0 is even faster than eSATA (external SATA) , almost doubles the speed.
USB 3.0 was first announced on September 18, 2007 at Intel Developer Forum.
The first samples of the USB 3.0 controller were distributed by NEC Electronics of Japan. Mass production is announced to begin in September at a rate of a million chips a month. NEC Electronics itself predicts that shipments of USB 3.0 PCs will reach about 140 million units in 2011, and about 340 million in 2012.
According to Nec Electronics, you will need only 70 seconds to transfer 25 Gbyte of video content on a blu-ray disc, compared to 14 minutes to transfer the same content when using the high-speed USB 2.0 with 480 Mbps transfer capability.
Apart from the announced speed, USB 3.0 establishes a communications pipe between the host and each device, in a host-directed protocol. In contrast, USB 2.0 broadcasts packet traffic to all devices. New power management features include support of idle, sleep and suspend states, as well as Link-, Device-, and Function-level power management.
Windows 7 drivers are under development but no public releases have been made available as of June 2009. The Linux kernel will support USB 3.0 with version 2.6.31, which will be released around August.
