 USB 3.0

The "SuperSpeed" USB Promotions Group was announced Tuesday at the Intel Developer Forum. The promotions group will get together with contributors over the next year to finalize a USB 3.0 spec that will, they hope, take care of our wired peripheral and syncing needs for another five years or more.
USB 3.0 is built upon, and is backwards-compatible with, the USB 2.0 "High Speed" spec. It would be generous to even call the specifications "early" at this stage, but the group still had lots of information about how USB 3.0 will work and what features it will provide. The spec should be finalized sometime in the middle of 2008, with initial devices available in '09, and broad deployment by 2010.
The main two goals of SuperSpeed USB are to provide a 10X boost in transfer rate (from 480-Mbits/s in USB 2.0 to 4.8 Gbits/s in USB 3.0), while dramatically lowering power consumption. One example of their speed goals is to transfer a 27GB HD movie to a portable device in 70 seconds. The same thing would take 15 minutes or more with HighSpeed USB (2.0). The SuperSpeed devices will use the same connectors and the same programming and device models as existing devices.
Consider that it takes maybe one or two tenths of a second to transfer a typical 4 Mbyte song to a portable music player with today's USB 2.0. That's "fast enough" for some users, but just try to fill up that 80-Gbyte iPod and you might as well walk away and cook dinner while you wait: 3,000 songs would take perhaps 400 to 600 seconds – up to 10 minutes.
Nobody wants to sit at their computer for that long, but if you could get it to under a minute, you're on to something. That's the performance aim of USB 3.0.

I find it rather ironic that USB came about because Steve Jobs got pissy/greedy about the royalties Apple deserved for firewire although many other companies had contributed to the technology. (He originally demanded one dollar per port in royalties for Apple.) Intel got pissed and started the development of USB... and the rest is history.

I thought USB came about a while before FireWire?

usb 1.0/1.1 did, but then firewire was developed, boasting 400 MBPS, then shortly after usb 2.0 came out and could run up to 480 MBPS...even though i think they have 800 MBPS firewire now...

Sorry, it was the USB 2.0 that was the result of the firewire royalty dispute. Michael Teener, the chief architect of Apple's Firewire technology, has a great read about what happened. http://www.teener.com/firewire/index.html:
Quote:
After Steve Jobs came back to Apple, he was somehow convinced that Apple should change the game midstream and ask for $1 per port for the Apple patents (his argument was that it was consistent with the MPEG patent fees). I left Apple before Steve came back, so I have no idea how this really happened.
This annoyed everyone (including yours truly) immensely ... particularly Intel which had sunk a lot of effort into 1394 (the improved 1394a-2000 and 1394b-2002 standards are partly based on Intel work). The faction of Intel that doesn't like open standards like 1394 used this as an excuse to drop 1394 support and bring out USB 2 instead. (There are lots of other stories about this whole process, but this is my favorite).
Simultaneously, Sony and the other 1394 backers pushed hard back at Apple noting that they all had patents too .... and if Apple wanted $1 port, so did they ... which meant that Apple would have to pay about $15 to every else to do Firewire ... not a pleasant picture. The result was the "1394 Licensing Authority".
