Here's the deal:
- Cables and connectors will be backward compatible with USB 1.1 and 2.0 specs.
- Cable thicker because of the five additional lines (the cable is now about the thickness of Cat5).
- USB 3.0 has a maximum transfer rate of 4.8Gbps.
- Data lanes separate for uploads/downloads.
- More efficient.
Expect USB 3.0 products to hit the shelves early 2010.
