It keeps getting faster, USB 3.0 SuperSpeed will be a massive 10 times faster than the 480Mbps limit of the old 2.0 spec. The example Intel likes to give out when talking about the new speed lets say transferring a 27GB HD movie to your future media player will only take 70 seconds with USB 3.0, while it would take 15 minutes or more with 2.0.Or this sounds just as good it’s the equivalent of moving almost one full CD’s worth of data in 1 second!
The good thing like all usb cables will be physically and functionally compatible with hardware from the older specs rah!.USB 3.0 achieves those speeds with a new plug and cable format, but it’s all backward-compatible with USB 2.0 and USB 1.1. Plug in your old device, and it will still work (at the older speed). Plug a USB 3.0 device into a USB 2.0 port, and it will run at the slower speed
Usb 3 should hit us early in 2010
