wow, yay....

There's a reason why usb 2.0 has been around for forever: It's enough.

Is there a reason for 3.0, besides running 5 or more studio quality cameras for your own personal TV station in your basement?

Since when was 10x faster speed not "good enough"? The only reason USB 3 hasn't been widely adopted yet it is relatively new and USB 2's ubiquity is unchallenged so far. If everyone thought like you, we would still be at 640KB of memory for our DOS systems.

[citation][nom]oneblackened[/nom]Wait a second, doesn't the 800 series of SB's already support that?[/citation]
I think it's not integrated. You get that from MB manufacturers.

????????USB 2.0 bottlenecks external drives pretty bad (even my 500gb 5400rpm USB drive, and I cringe when I'm in a situation where I can't use eSata to connect my 7200rpm drive). So yes, there is a reason for USB 3.0

Everybody should cut this guy some slack... It took him a long time to dial-up and get on-line to write that comment.

Thunderbolt is prob going go the way of Firewire. Most of your avg pc users are more concernd about comtability over anything else, which is why USB is not going to get knocked off its thrown for a long time. USB has been out now for a little over a decade with millions upon millions of products that support USB and becuse of that. It has become apart of the everyday pc users lives and one of the the reason why it's still around and Firewire is all but dead is because of its wide range of compatibilty over the years.

I'm more concerned for dual channel memory support. That small change would further widen the massive performance gap between the fusion and atom platforms.


If I remember correctly, USB 2.0 wasn't adopted very quickly either over the 1.1 standard. Even 1.1 stuck around for many years afterwards.

That's the theoretical peak of the interface. Your actual speeds will be far lower. Even with enhanced drivers designed for specific products, USB 2.0 can't put out more than 40MB/s.

Plug any mechanical external drive into a USB 2.0 port and benchmark it, you'll see. Most mechanical drives easily exceed 100MB/s these days, so the extra overhead of USB 3.0 is very much welcomed.

[citation][nom]memadmax[/nom]That 30 meg a sec is prolly just your hard drive/controller or something else cause 2.0 does twice that.[/citation]

Nope, back to the drawing board!
 
USB 3.0 is a welcome addition, its the next evolution in the USB standard. What I really wanted was "Lightpeak" to support full HD video displays, basically I want my system to be in my computer room but be able to display to the living rooms HD display. If they can combine this with a USB channel (keyboard / mouse) and audio channels, then it would revolutionize how home computing is done.

But it looks like Intel is trying to replace the open USB standard with their propriety Intel-only LP standard and not even bothering with the remote display capability.

What's so good about integrated USB 3.0 controller over a a NEC controller?
(forgive any inconsistencies in my question, altough I believe it's understandable)

Fantastic news, hopefully this means that Bulldozer will also support USB 3 natively. I can't see AMD supporting USB3 for their laptop systems but not there high end PCs.
 
Cost for one, simplicity of design for another. MB manufacturers having to add another chip to a board raise's the cost of the design. Low power devices have a requirement to be cheap and small, add on chips conflict with this requirement.

Just look back in the days with IDE controllers and IO controllers were "add in" cards and the issues those caused.

[citation][nom]danwat1234[/nom]What's an NEC controller?[/citation]
Currently all motherboards that have support for USB 3.0 are using a controller chip manufactured by NEC, and fused to the motherboard. The motherboard chipset doesn't have any native support, so this is the only form of USB 3.0 for now.

NEC is making a fortune I'm sure.

For one, it would reduce data latency slightly. It would also be cheaper since it would be integrated within the system's chipset rather than buying a chip from a 3rd party. Having the USB 3.0 option right now usually increases the board cost by at least another $15~$20.

I have yet to see USB HDD that can bottleneck USB 2.0 link. Most HDDs I have do something like 25-35 megabytes per second, while USB 2.0 could handle up to 60.
