USB 3.0 Specifications released

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.

Cough**** The USB 3.0 will support speeds up to 4.8 Gbps, roughly 10 times faster than USB 2.0 Thats what Neowin tells us

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.

Eh? You lost me. You realise the lower case b refers to bits, of which there are 8 per a byte (upper case B)

4800 (4.8Gb)/8 = 600 (600MB)

They, Neowin and the Promoter Group, are both listing the same speed using different units of measure.

Curious.. can anyone provide a link to research done to increase the firewire spec to something nearly as impressive?

Bloody hell, 4.8GB? That's mad.

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

Not true. USB 2.0's practical speed limit is about 30MB/s. There's a reason performance drives come with eSata as well as USB.

I think your thinking of Sata specs. They certainly can meet USB's.

It's worth noting that the seemingly ridiculous speed will probably be shared among several devices, so it makes sense to have a lot.

Sweet then we fall back and think, that's faster than my HDD can write or read. About 300MB/s - hmm i wonder when will we see normal (non RAID) drives do that?

i swear... i hate when people do this... they should have gave us something fast like USB 3.0 a good 3-4years ago.

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 ... so i figure they should try making something that can pump out a sustained 100MB/s.... cause it's unlikely that would be 'slow' anytime in the next 5 (maybe even 10 years) ... and even if im wrong i doubt it would be slow slow like USB 1 is considered.

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

We do actually use USB 2.0 to its fullest. The reason why they cap at about 33MB/s read is actually because the practical limit of USB 2.0 is about 30MB/s. The 60MB/s limit is just theoretical and has probably never been achieved anywhere.

There's a reason why people use eSata for their hard drives and performance drives. USB 2.0 isn't fast enough.

i find it funny that it is faster then sata by a lot

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.

omg

the new spec 200x faster ! ???

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.

You can actually wirelessly sync your iPhone and iPod with AmaroK already. Yeah that's right, a third party music player that isn't designed for Apple can do something iTunes can't?

Zune wireless sync anyone? :)

Zune wireless FTW. My Zune syncs automatically to my computer while it is on the charger in my car. Awesome.

Finally..

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...

Just when you're about to buy that notebook.. they announce Windows 8, Bluetooth 3.0 is almost ready, some new awesome Fusion processor that combines videocards and processors is about to be releases making all other computers look like simple calculators.

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..

Haha, we need a new logo. The Hi-Speed USB just doesn't cut it anymore.
Hopefully manufacturers speed up delivery of this.

They should go for a simple USB 3 logo... or USB III
