More USB 3.0 demos tip up
USB 3.0 IS gaining momentum, with a plethora of companies showing off their new super-speed wares at a USB Developers Conference in Tokyo.
After NEC announced its (and the world's) first USB host controller supporting the new USB 3.0 standard on Monday, other firms have been quick to get in line with their own offerings and demos, most notably Fujitsu Microelectronics, LucidPort Technology and Fresco Logic.
USB 3.0, AKA SuperSpeed USB, the spec for which was released in November 2008, will deliver throughput at 5Gbps, 10 times that of USB 2.0. The standard is also backwardly compatible, uses less power, boasts simultaneous bi-directional data transmission and is generally nifty in all things pertaining to the movement of HD content and multi-Gigabyte sized files between PCs and external storage devices.
At the show, fabless semi, Fresco Logic, demonstrated the potential for system-level interoperability between its SuperSpeed USB extensible host controller interface (xHCI) adapter and a USB 3.0 SATA bridge device from Fujitsu Microelectronics.
In another demo, NEC showed a PC host transferring data to a mass-storage device from LucidPort.
Jeff Ravencraft, USB-IF president and chairman said he was pleased with the "intense interest and market need" surrounding USB 3.0, adding its features had "resulted in excitement from silicon vendors, electronics manufacturers, and consumers alike."
The USB-IF reckons USB 3.0 products will be available for punter purchase by early 2010.
Meanwhile, IDC is predicting SuperSpeed USB will ship in 45 per cent of mobile PCs by 2012. µ

Its Two Way communication that reminded me of simpler, two way, internal two way Crossbar hyped for cpu/gpu. Larrabee to be exact.
Recently someone published photos of "Larrabee", except larrabee has two way crossbar, at least thats what we are told.
NO SUCH MECHANISM WAS PRESENT IN PHOTOS.
Picture was most likely Xbox 360 part(First Shots Had 24 ?SIMDS or Processors/cores?, Latter Altered to appear as more.
, NOT Larrabee at ALL. So Don't Get Your Hopes Up. There IS NO Known Samples of larrabee in Existence.
In Fact, Leo LaPorte Stated It Well on Friday to PC Perspective, whom splashed supposed Larrabee Photos about.
In Leo La Porte words: "Larrabee, Refresh My Memory, Whats Larrabee?" No Truer words could Be stated.
So Be Warned.
On USB 3.0, two way IS bit like doubling potential, with capability for quite large array, chattering ALL Time. You Can Tell Intrest When Companies Come out With Samples In Matter Of Days Of Each Other.
Larrabee NO. USB3 YES.
That was the first post you've written that I understood. Sorry to disappoint you. Good luck tomorrow!
Vondrashek, we had not see the final silicon of Larabbe yet, so I think it's nonsense to argue over that.
Either Drashek the person is having a bad day, or Drashek the bot just had its algorithms upgraded.
Are we sure there's nothing DRM in this specification, ala HDMI cables?
I much prefer Firewire and I hope that with the upcoming Firewire S3200 (3.2Gb/s) more vendors will get interested.
Firewire advantages over USB:
* Guaranteed 97% throughput where as USB in only around 50%. So Firewire S3200 is still going to be faster that USB 3.0.
* Firewire hardware is in the device, so you can plug S3200 devices into a Firewire 800 port and still get S3200 speeds!! Awesome!
* Firewire protocol is much better design. It even allows for tcp/ip networking (all built-in).
*Firewire allows higher power throughput, so devices that use more power can be used without external power bricks.
* Firewire doesn't require your system's CPU to function (unlike USB). So I can plug my firewire harddrive directly into my Video Recorder (no pc required).
The list goes on! Vendors, please look at Firewire as well!!
I can only wish that USB3 devices will be more compliant that USB2 ones are.
Some of the cost cutting exercises that manufacturers get up just make my life harder.
I'm sick of buying 7 port USB2 hubs which only have 2A power supplies.
You try finding one that supplies 3.5A!
Buying devices that need more than the rated 0.5A so you end up using 2 USB sockets.
Or coming across Laptops which can't deliver 0.5A on each and every one of its USB sockets!
Well I can wish... :-)
Hopefully too I might be able to stop having to make sure a USB card has NEC written on it rather then VIA.
Why VIA never got its USB controllers right I'll never know. Thet also rarely push out enough power.
Store owners used to look puzzled when I asked them to open the box to make sure it wasnt VIA.
Had to be NEC all the way.
As for Firewire...just let it go, it had its day.
USB vs. Firewire: Can you say "convergence"? How many different serial multidrop short-distance "standards" do we need? Most of "advantages" listed for Firewire will be met with USB 3.0.
Agreed with NEC vs. VIA on USB implementation; VIA cut far too many corners.
Drashek, are you feeling okay? You're actually making sense.
Larabee doesn't exist on silicon. As far as I'm concerned, it is a red herring. Intel is only trying to screw around with AMD and NVIDIA. Probably thought it would drive NVIDIA into failure. Turns out NVIDIA doesn't need help with that; doing quite poorly anyway. Or maybe Larabee was someone's wet dream at Intel, and they aren't really able to design/fabricate an actual working part that will be competitive. Who knows? All I know is that Larabee has been talked about for years, but NO silicon.
Ok, guys. Von Drashek is just back on his meds. Don't worry it won't last. He will be off of them soon enough, only to go back on them for awhile. We have all seen the cycle before and it will happen again. Though it is nice to easily understand what he is saying.
I'm looking forward to these ports becoming as ubiquitous as USB 2.0 ports are now. It'll mean the end of eSATA and Firewire, but no real loss there. eSATA didn't take off like it could have due to limited application, and Firewire has always been too expensive, what with the patent and licensing hoops implementers had to jump through. With USB 3.0, we can get rid of two more under-utilized oddball connectors on the front and rear I/O panels of our computers.
Again no ability to power an external HDD without a seperate PSU. What were they thinking? Safety issues?
