Title: USB 3.0
Post by: luck of the irish on June 26, 2009, 02:36:06 PM
I have heard from a reliable source that USB 3.0 the newer and faster edition of the USB ports is going to be lead by Linux i.e. Linux will be the first to integrate USB 3.0

That would have to be supported by the hardware as well.

<edit> Of course it would step down to USB 2 if they do it right.  I can't imagine them messing that up. </edit>

According to Intel, the Linux kernel is shortly to be updated to integrate the faster USB 3.0.  The transfer rate is ten times faster, sounds like good news for Linux users

The hardware still has to support it.

No ones going to be first on this...by the time Linux integrates it Windows will have it...
But Quantos is correct...

Thanks patio.  There's nothing like a good pat on the back as a pick me up  8)

well yes of course, the new computers will have the supporting hardware though correct.

Hopefully(and probably) it'll still be backwards compatible.

And also, perhaps once they get it on PCs, no more Windows ReadyBoost?

Then it won't be Linux to be the first to have it.  The hardware manufacturers won't touch it until there is a standard. 
Linux just doesn't have the market share to decide what those standards will be.

I don't see why they should bother.  USB 2.0 is fast enough, right?

Computers are never fast enough, that's why we upgrade :)

It was actually predicted by a man by the name of Michael Moore, that we would build things smaller and smaller, it is going to keep getting smaller (if one would like formula please don't hesitate to ask me)

err...

Michael Moore?

*censored*?

"Moore's Law" which appears to be what you've merely rephrased here, was coined by Gordon Moore.

err... That doesn't make sense- Faster USB would INCREASE readyboost performance, so I'm not sure what you mean...

Sorry, meant Gordon Moore he was the co-founder of Fairchild and Intel Corporation. When Moore looked back in time, he noticed that every 2 years, the number of transistors on his company's IC's had doubled. I.e. he predicted that the number of transistors on an IC will double every 2 years.

I get the impression that luck of the irish is in fact ireland-1.

Hopefully(and probably) it'll still be backwards compatible.

Not necessarily, there comes a time in every standard's life when backwards compatibility is not feasible.  We'll just have to wait and find out.

Michael Moore is an idiot anyways...

Hopefully, take for example the Gameboy Line and the DS line.
They stopped the backwards compatiblity with original GB and GBC on the Gameboy Advance SP.
And now they've discontinued backwards compatiblity with GBA games on the DSi.

It's still a good idea to keep backwards compatiblity for thoses who are catching up.

Nintendo isn't exactly known for "backwards compatibility" by any means. NES games don't play in a SNES. SNES games don't play in an N64. Their gameboy's were different in that they were compatible for the most part- but how long did the PC have ISA? over 20 years. More to the point, other technologies have gone through numerous revisions and still remained backwards compatible to those expecting the previous revisions namely, Windows. Not to of course get into an open debate about it here, but the main reason older programs don't work with a newer Windows OS was simply because the programmers of the older program took shortcuts. This can be seen fairly easily when you run some windows 9x designed games on XP, thus moving it from the relatively lax security of the 9x environment to the stricter virtualized NT based OS. The same effect is seen from XP to Vista, again, due to the fact that Vista has a different security model.

It will simply be done "because it can" or as in the case of "Everest" (the mountain) because it's there. truenorth

Good point, BC.

Backwards compatiblity is good in some ways/bad in others(especially when it comes to PC security)

I don't see why they should bother.  USB 2.0 is fast enough, right?
USB 2.0 = 480 Mbits/s.  USB 3.0 = 4800 Mbits/s (4.8 Gbp/s).  Which one would you choose if you dealt largely with big files?

:O thank you, that was interesting, I now know that if it is compatable I will be buying the USB 3.0

Then it won't be Linux to be the first to have it.  The hardware manufacturers won't touch it until there is a standard. 
  The USB 3.0 standard has existed for some time now.  USB 3.0 will appear in OSes when the USB 3.0 ICs appear in computers probably at the end of summer 2009.  USB 3.0 means data at 'movie' speeds - 5 gigabites per second.

  Intel is a primary promoter and developer of USB.  Intel has also moved into directly supporting Linux software.  USB from Intel will be available in all Intel supported OSes when hardware arrives.

  Data that once took 22 minutes with the original USB will transfer in 3.3 seconds with USB 3.0.  USB 3.0 is for real time video and other large data applications.

USB 3.0 will support the legacy versions.
