Yeah, I saw that too. I wondered about the "4.7 times faster" though. USB3 was supposed to be at the speed of eSata which should make it even faster than 4.7 times.

eSata isn't really any faster then your regular internal sata simply due to being extended outside of the case. You still use the same bus but plug into an external port extended from the board there. Some cases come with eSata ports while you can also add an adapter that fits into a PCI slot opeining.

While the present external usb drives tent to see slower access times over those installed internally the new 3.0 bus would seem to change a few things there. That will be especially helpful with something like the XP Mode that sees integrated components with usb support present.

Once prices start falling on SSDs watch out however! Those will be a stiff competitor to the ATA form presently common in use whether internal or external.

Right, but USB3 was supposed to be at the same speed as eSata - 3Gb/sec. But 4.7 times faster than USB2 (480Mb/sec) is a far cry from 3Gb/sec.

The new usb standard will do precisely that boost the overall performance and access times for external drives when using the new usb bus. Presently many prefer eSata and even Firewire over the 2.0 bus simply for the gains seen with those.

7 by default already sees support for 3.0 included. That won't be helpful for those running Intel chipsets however not until at least 2011. NVIDIA confirms Intel chipsets won't support USB 3.0 until 2011 -- Engadget

This is where the SP1 for 7 will need to offer some help along with updates from Intel for their own chipsets.
