SuperSpeed USB boosts speed 10x over USB 2.0
A variety of USB 3.0 demonstrations have been planned for the Intel Developer Forum scheduled next week, according to CNET News. Grey Point Research will bring one of its prototype cameras with a 3-megapixel Sony CMOS sensor. The camera will stream uncompressed 1080p video at 60fps to a laptop outfitted with a SuperSpeed USB ExpressCard from Fresco Logic.
A Fujitsu laptop, allegedly the first with built-in USB 3.0 components, will be on hand to preview data transfer rates with an external USB 3.0 drive built by Buffalo technology. Asus plans to demonstrate its X58 motherboard with USB 3.0 and support for the new USB Attached SCSI Protocol (UASP).
The new format is claimed to peak at 5Gb/s, enabling 25GB of data to be transferred in just 70 seconds. The same amount of data currently takes nearly 15 minutes to transfer via USB 2.0, while even FireWire 800 doesn't meet USB 3.0's speed capabilities.
Connected devices will be able to draw more power from the new connection, eliminating the need for AC adapters on many external drives. Despite the boost in speed, the standard is still backwards-compatible with USB 2.0 devices.
The IDF previews are scheduled to begin Tuesday at the Moscone Center in San Francisco.

5 Gb/s - yeah right
This is complete bogus. The current USB 2.0 standard, on a 2.2GHz Core 2 Duo machine will take at least 15 minutes to transfer 4GB ... this is in optimum conditions. In reality it will take 20 minutes. Where as ... FireWire 400 does it in 5 minutes or less. 25GB of date on USB 2.0 will take easily 2 hours if not more ... never in 15 minutes.
I believe USB 3.0 will be just like USB 2.0 in terms of real performance. Current USB 2.0 is about three times SLOWER than FireWire 400. By my rough calculation, it'll be about the same speed as FireWire 800, if we're lucky.
