USB 3.0 to arrive at superspeed in 2008
Author: Tim SmalleyPublished: 19th September 2007
Gelsinger says that USB 3.0's specifications will be finalised in the first half of 2008.
The group, which consists of HP, Intel, Microsoft, NEC, NXP and Texas Instruments aims to deliver a final specification for the third generation of USB in the first half of 2008.
Intel said that USB 3.0 will be backwards compatible with current devices and will deliver more than 10 times the bandwidth of USB 2.0. Additionally, the new specification will enable better power efficiency and is expected to support both copper and optical interconnects.
Initial USB 3.0 devices and implementations are expected to be in the form of discrete silicon.
In order to explain the importance of the USB interconnect and how it has transformed the way we use our PCs, Gelsinger said that over 6.2 billion USB devices had shipped since 2001, with 2.1 billion of those shipping during 2006.
He pointed out the usual list of USB-enabled devices that most computers use: keyboards, mice, digital cameras, printers (and so on), and then revealed the USB cool wall, which featured record players, mini-fridges and mittens, all of which were USB-powered.

Current USB 2.0 devices hitting 30-40MBytes/s but I just can't see USB3.0 stuff hitting 300MBytes/s can you? For one, copying from a USB stick to your hard drive, even a 15,000 rpm drive won't be able to keep up! It would have to be a flash-to-flash transfer to really benefit
what i want to see is a little higher / or same transfer speed as USB2.0, while having a very, very low latency. so that everything will be really responsive. eg, when copying to USB HDD, it's all nice and fast, but as soon as you have multiple copy instances, it goes to a halt. so large chunks of data while having a low latency is what they should be concentrating one, not pure speed.
Most of my usb 2.0 flash memory only deliver about 15-25 MB/s. Why your devices get such an awesome speed?

I totally agree that 10x speed is a tough competitor to hard disks. But with such a high speed, it would reqiure a more powerful chip. So how does USB3 get a low energy consumption?
A usb networking protocal like firewire has to me would be the greatest improvment.
has anyone heard about wireless usb?
edit:
how about running applications and files of an external drive? i think this would be very nice, don't you? and with some kind of network interface were you can easily link 2 pcs and share files and other stuff this could easily pwn.
I dont even use up any of the 10 USB 2.0 ports to the limits yet, even with some SATA-II to usb drives.
Optical sound's rather cool, but how does one go about powering there usb device via optical, so I guess means the need for external power, more energy effcient they say? :|
I think your right about firewire, they do make it hard for implementors although have to say the large product manufacturer out there using these interfaces look towards selling much much more than 1000 units.
From the looks of the image above, it looks like the optical is in the same plug as the data. So the power would be carried over the same copper, and the data over the optical (The two spots on the "Tongue" in the USB plug)
And that does still pwn even the quickest HDDs :(
It would have to be Ram-Ram :p and then you would be very limited by the USB bus ;)

...though you could connect a gigabit ethernet connection through it too if you wanted.I was kind of hoping they'd increase the power part by "more than 10x" as well, but sadly that doesn't look like it's happened. Mains or 12v rail bypass would be cool - kilowattage :D (if a little dangerous if they got the plug design wrong).
