USB 3.0 To Boost Peripherals to Multi-Gigabit Speeds

The "SuperSpeed" USB Promotions Group was announced Tuesday at the Intel Developer Forum. The promotions group will get together with contributors over the next year to finalize a USB 3.0 spec that will, they hope, take care of our wired peripheral and syncing needs for another five years or more.

USB 3.0 is built upon, and is backwards-compatible with, the USB 2.0 "High Speed" spec. It would be generous to even call the specifications "early" at this stage, but the group still had lots of information about how USB 3.0 will work and what features it will provide. The spec should be finalized sometime in the middle of 2008, with initial devices available in '09, and broad deployment by 2010.

The main two goals of SuperSpeed USB are to provide a 10X boost in transfer rate (from 480-Mbits/s in USB 2.0 to 4.8 Gbits/s in USB 3.0), while dramatically lowering power consumption. One example of their speed goals is to transfer a 27GB HD movie to a portable device in 70 seconds. The same thing would take 15 minutes or more with HighSpeed USB (2.0). The SuperSpeed devices will use the same connectors and the same programming and device models as existing devices.

about time, i wonder why they just did not goto USB 3.0 in the first place right after USB1 ... this would it would make it somewhat future proof ;)

although USB 2.0 is still "good enough" for external hdd's for transfers and data backup here and there... it would be nice to get much faster speeds like USB 3.0 offers.

cause after i got used to SATAII hard drives when i transfer **** to my external 10GB laptop hdd type thing it does takes quite a bit longer lol

Right... And why didn't they just go straight to quad-core after the 8086 CPU? Its called technology. It doesn't move instantly. It grows steadily. Live with it.

I hope they have sped up the usb polling rate so controllers, mice etc. have reduced input lag and more accuracy.

That'd be Wireless USB :)

There will be a day in which I don't even have to take my USB out of my pocket to upload a virus to a computer.... ah the possibilities

No need for internal hard drives anymore. Just carry around your USB drive and run everything from that. Now we just need non-hardware specific operating systems ... :P

Hope hard drives will develope faster than others...

Agreed. No point of making super fast USB to transfer at 4.8Gbits if your HDD can only read 100Mbits. But its nice to know you have than extra bandwidth to spare.

SATA II can theorectically read at 3.0 Gb/s, fast enough

Yes, but no. Even with a disk stripe, my SATA (1) drives only go to a maximum of about 110 megs/sec on ACTUALL throughput. I'm sure it's gonna be the same with this new USB 3.0 deal.

That would be putting a ton of work on your CPU wouldn't it? Also say goodbye to 3D acceleration.

Like most USB devices wouldn't all of that be built into the monitor itself already?

"One example of their speed goals is to transfer a 27GB HD movie to a portable device in 70 seconds"

Those sort of speeds are nice to have and all that but unless some big advances in SSD tech is achieved soon then the vast majority of the speed won't be utilised. A 1Gbit LAN connection already saturates the write speed of today's hard drives almost entirely.

The whole point is to future proof it.

Does it matter if the speed is not utilized? Not really.

All that matters is the current interface no longer has enough bandwidth to transfer data at maximum speeds.
