This is a little better than half of the rated speed of USB 3.0....350MBps=2.8Gbps.]]>Aug 21st 2008 9:07AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/
Things are looking good for USB 3.0]]>Aug 21st 2008 9:11AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/
USB 2.0 = ~30-35MB/sec (real-world)
Firewire 400 = 35-45MB/sec (real-world
Firewire 800 = 60-70MB/sec (real-world)
SATA I aka SATA 150 = 150MB/sec
SATA II aka SATA 300 = 300MB/sec (current and eSATA)
USB 3.0 = 350MB/sec
Firewire 3200 = ? (will most likely be real close to 350MB/sec max)
SATA III aka SATA 600 = 600MB/sec]]>Aug 22nd 2008 2:21AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/Aug 21st 2008 8:56AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/Aug 21st 2008 9:11AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/It's a question of "Can"

Wired USB has come to an end with the introduction of the Certified Wireless USB 1.0 approved in May 2005. Everything will start to go wireless when wireless USB hub & USB dongles begin appearing in Q2 2006"

I have one of those cheap USB drives. Now I know why I could not find a mbps rating for it. I guess it will do for backing up, but it is annoyingly slow for normal use, especially if you are getting to it via a Share on the LAN. Must be 10 mbps. Yes it is on a 2.0 port. Tried it on another machine with a usb 1 port; that truly bogged down to near useless.]]>Aug 21st 2008 10:29AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/Aug 21st 2008 11:21AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/Aug 21st 2008 9:29AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/
As for SATA, didn't SATA 3 just get certified too? Nobody is standing still.

And is USB 3 free of the problems that made USB 2 so much slower than its rated speed that Firewire 400 continually proved the faster way to go in spite of being rated at 400 while USB 2 was 480? The problems I'm referring to is the fact that you had to have a port for each peripheral, and that the processor has to be involved with moving data, whereas in Firewire the processor was left alone. Streaming is clearly better than packet-based data transfer for anything other than a bunch of tiny files.]]>Aug 21st 2008 10:43AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/Aug 21st 2008 11:02AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/Aug 21st 2008 10:57AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/Aug 21st 2008 11:27AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/People said that CAT 5 cable was going to go the way of the dodo, and that all future networks would be wireless... That hasn't happened yet, and people are now talking about residential fiber optic installations (I live adjacent to a pretty wealthy neighborhood that seems to get some bizarre installation requests for new houses).

You'll still see advances in wired standards to send and receive data.]]>Aug 21st 2008 11:35PMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/that's a 500Mhz powerpc core + gate array
the're thinking waaay ahead of us.
then again, that makes battery life waaay worse.]]>Aug 21st 2008 11:20AMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/Aug 21st 2008 1:21PMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/Aug 21st 2008 1:36PMhttp://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/http://www.engadget.com/2008/08/21/usb-3-0-data-transfer-demonstrated-at-idf/
