The new standard for USB (Universal Serial Bus) 3.0, also known as SuperSpeed USB, has released the specifications for its next major upgrade. USB 3.0 is meant to surpass its current predecessor USB 2.0, which supports up to 480 Mbps data transfer. The USB 3.0 will support speeds up to 4.8 Gbps, roughly 10 times faster than USB 2.0.The new standard is expected to be more power-efficient over its predecessor. Your old devices will not be garbage just yet, since USB 3.0 will be fully backwards compatible with your old devices, supporting USB 1.0, 1.1 and 2.0.
The switch over from USB 2.0 to USB 3.0 on your hardware will hopefully take place late in 2009, where media devices will be the first to see the upgrade in things such as, external hard drives, flash drives, digital cameras, and personal media players.
Hopefully manufacturers speed up delivery of this.

They should go for a simple USB 3 logo... or USB III
Universal Serial Three?
Now I'll wait more 8 or 9 months and buy a Notebook with USB 3.0, Sata 3.0, using DDR 3 and I hope by that time Core I7 ( Intel Nehalem microarchitecture ) is already available in notebooks..
Also if everything goes well Windows 7 will be available by that time, so already bring Windows 7 and no problems with notebook not supporting 100% of all the drivers needed for Windows 7 to run on it perfectly..
Nice notebook I'm going to have, well if they don't mess up the dates...
Point taken, but USB 3.0 + DDR3 and Core I7 should make some years of being on the same plate from a computer generation point..
I hope you understand what I mean..
agreed.
I'd rather see WiFi USB. Imagine wireless iPod sync

I think the spec is fast enough to be basically faster then the access speeds of most hard drives to be future proof for quite a while.

That's not the same technology. USB is Serial, Bluetooth is wireless. Bluetooth 2.1 currently has 2.1 Mbps (pure coincidence that the version number matches the speed). Bluetooth 3.0 is supposed to bump that up to 480 Mbps, which opens the door to wireless external drives & high-speed synching with cameras, digital portable players, mobile phones, etc.
Zune wireless sync anyone?

omg
the new spec 200x faster ! ???
+1!

I disagree it might not be as fast as SATA the just because it says 4.8 Gbps, when transferring files it might be slower than SATA. Look up USB vs firewire for reference.
+1 as well. We already have that over here!
Zune wireless FTW. My Zune syncs automatically to my computer while it is on the charger in my car. Awesome.
or was it one of those things it was 'to expensive to mass produce for a pc' type thing at the time?
cause when they make USB 3.0 they need to make it plenty fast ... quite faster than anything that we would need within the next 5-ish years... i.e. basically make it semi-future proof if possible

usb 1.1 12 Mbit ~1.5 MB
while Usb 2 480 Mbit ~60MB
now usb 3.0 4800 Mbit/4.8Gbit ~600MB !
USB 1.1 ===> usb 2 40x faster
usb 2 ====> usb 3 10x faster
so they already give us something that last us a while
btw we dont use usb 2 at it fullest yet (the best usb flash ~33mb read ~22 write ?)
i believe usb 3.0 would make it better for external new harddrives
There's a reason why people use eSata for their hard drives and performance drives. USB 2.0 isn't fast enough.
4.8 Gbps!
lol don't be too mean
Anyway, I'll wait until a USB 3.0 enabled External Hard Drive comes out, and then I'll buy one (alongside a USB 3.0 card, obviously).

most (all?) harddrives don't even reach usb2 speed

u fail
I hope you are joking because that isn't true.
i think you mean it's 3.2Gbps not Mbps
That's lame. I'll get a new computer regardless so no worries.
The USB 3.0 Promoter Group has now announced the final specification for the USB 3.0 interface, which will also be known as SuperSpeed USB and offer transfer rates up to 600MB/s, more than ten times faster than USB 2.0.

4800 (4.8Gb)/8 = 600 (600MB)
They, Neowin and the Promoter Group, are both listing the same speed using different units of measure.
