About month ago Intel has released USB 3.0 or "SuperSpeed" USB specifications. It is not released to public but to technology partners and manufactures. Get it from here if you have xHCI contributor agreement. Release of this information was not as simple as it sounds. Intel was accused of withholding the information so they could get a head start in design and manufacture of first boards and devices.
Eventually, information was released and USB 3.0 will have the following specifications:
- 5 Gb/s data rate
- Fast Sync-N-Go
- download 27 GB in 60 - 70 sec
- Optimized power efficiency
- lower active and idle power requirements
- Backward compatibility with USB 2.0
- new devices interoperable with USB 2.0 platform
- hosts support USB 2.0 legacy devices
USB 3 cable interface
Results of speed test. If this is real life test this means it is very fast.
First commercial devices with USB 3.0 are not expected before 2010 and for widespread use until 2012.
