USB 3.0 Proposed

Intel has announced the formation of the USB 3.0 promoters group, a consortium that aims to create a "super speed personal USB interconnect."

The first members of the promoter group (HP, Intel, Microsoft, NEC Corporation, NXP Semiconductors and Texas Instruments) said that USB 3.0 will deliver more than ten times the data transfer bandwidth of USB 2.0, which tops out at 480 Mb/s. The new interface will be designed to be used in consumer electronics and mobile applications and able to deal with digital media file sizes that are likely to exceed 25 GB.

Intel stated that USB 3.0 will be based on current USB technology and ports and cabling will be backwards compatible; however version 3.0 will offer enhancements for better protocol efficiency and lower power consumption. The development group will also integrate an upgrade path to optical capabilities for USB. A completed USB 3.0 specification is expected to be released in the first half of 2008.

Finally USB can be used in HDs and they can be super fast!

You know, I wonder how all the old electronics are going to cope with this... I remember that when they made 2.0 I practically cried because everything was faster, but it overvolted my old items I had... stupid 2.0... I am quite curious: how do they make 3.0 faster? Magic? I think not!

Oh that is a good point... USB is now faster than SATA!!! Or so they say...

Probably not since currant USB really can only hold a sustained rate of about 30 mb/s which multiplied by 10 is 300 mb/s. SATA is rated at 300 mb/s between the controller and the drive. 3 gb/s between the controller and the sb. So all in all, SATA is still faster if looked at realistic speeds because I believe SATA can run closer to the limits than us.

I was thinking that way as well... Realistically you say...

This maybe a stupid question, would this enable the use of external graphics cards?

Hell if it can pull off the full 4.8 gb/s yeah. But the thing is there's going to be overhead, and the usb bus is shared with everything that's connected onto it etc. So it's not really as good as pci-e, and anyways, pci-e 2.0 has standards for external gfx cards.

Nice find :D

USB2.0 was getting pretty slow for my external HD :(

stupid intel. When will everyone learn? USB sucks. Always has (and most likely always will).
1394 is the way to go. Who wants slow speeds and high CPU utilization?

Reminds me of this huge argument we had with an instructor that thought intel was cool. Took us forever to get him to believe that 1394a slaughters usb 2.0 (same thing happened with him and CPU performance a couple yrs ago). Theoretical and synthetic tests doesn't mean jack (especially with intel haha).

The only reason I don't think it would work that well is because USB sends information in bursts, whereas FIREWIRE sends information streaming.

No matter if it's faster or not, I have 2 Firewire 400 ports on my PC, they've never been used. USB is just more readily available. (Also its near impossible to find a mobo with 1394b)

True, but it's still faster. ;)

Wonder if it can push more power than the current 500mA.

firewire is faster, since it does streaming. but USB is cheaper, and more common. the compatibility is the big thing, even a pentium 2 can use a flash drive, whereas firewire as A and B that arent compatible, requiring different devices/cables to get anything to work.

USB3 has to beat firewire 800 (B) and hopefully it supports streaming, and not just bursts...

Fire wire costs far too much per port to make it an industry standard, a USB port costs approx 15 cents per port while Firewire costs $1 per port. If Apple wasn't so greedy they could have had the industry standard but Apples greed over firewire shows why single small collaboratives should not own the rights to any industry standard that is to be a world wide standard.

Usb is the peoples champion!

SATA 6 is due to be launched soon. It has 6gb transfer rate

Don't get all excited just yet, guys!

Sure, USB has the bandwidth, but it Sucks at read/write times. It's as slow as a 4200RPM HDD. What we need is improvement in that area.. if possible.

Then, we could hook up a USB flash drive and it'll be as fast as an SSD.

Apparently the Guru is here to make us all Disciples of 1394 ;)

Please qualify your original statement. I fail to see how you proved Intel is stupid... and for that matter I don't think you offered a convincing argument that USB sucks. Are you saying it sucks because its slower than 1394? How does that follow? Does this mean anything that's not the fastest sucks? Using a similar argument, I could state that 1394 sucks because eSATA is faster.

You must see the foolishness in this logic.

Do I think 1394 is superior to USB? Yes. Would it be great if it had overtaken the personal electronics & peripherals market instead of USB? Yes. Does that make Intel or USB stupid? Certainly not.

Save the bashing/flaming for a different forum please.
