Finally a USB 3.0 Device?

USB 3.0 specifications have been out since last quarter of 2008, and devices supporting it are rumoured to be out by the end of this year. USB 3.0 is touted to reach speeds of up to 4.8Gbps, compared to USB 2.0 480Mbps. Seems like finally USB 3.0 is going to see some light of the day.

Fujitsu recently announced a USB 3.0 to Sata bridge chip, with in-built AES encryption/decyption for secure storage. What does this mean? I would say faster copying to portable storage devices. An example was given that a 2 hour HD movie can be copied to a USB 3.0 3.5 inch hard disk drive in 3 to 4 minutes (I assumed no encryption). Now... That is fast.

USB 3.0 is backward compatible with the previous versions of USB too, so do not be too worried about your previous USB 2.0 devices.

However, one catch though to this piece of news. It would most probably be only available next year. Chicken and egg problem again I assume. How to sell USB 3.0 devices if there are no machines with USB 3.0 ports?
