The all new USB (Universal Serial Bus) 3.0 specs, which can handle data transfers of up to 4.8 Gbps, is the leader to USB 2.0 and should be pop up in devices in late 2009.
The USB 3.0 spec, which is also called as “SuperSpeed” USB, will support up to 10 times faster data transfers than the normal USB 2.0 which is predicted to be lower power consuming.
“SuperSpeed USB is the next advancement in ubiquitous technology,” Jeff Ravencraft, the president of the USB Implementers Forum (USB-IF), the industry group that promotes USB technology, said in a statement on Monday. “Today’s consumers are using rich media and large digital files that need to be easily and quickly transferred from PCs to devices and vice versa. SuperSpeed USB meets the needs of everyone, from the tech-savvy executive to the average home user.”
As for backwards compatibility for this USB 3.0:
The USB 3.0 will remain backwards compatible with USB 2.0 as long as the Type A connector is used. While USB 2.0 is based on uni-directional data flow with negotiated directional bus transitions, USB 3.0 supports simultaneous bi-directional data flows by the use of dual-simplex four-wire differential signal wiring as compared to half-duplex two wire differential wiring in USB 2.0 type.
What does that mean? We’re not so sure, but it sounds fast, fast, really fast. Kudos for the USB Implementers Forum for getting this USB 3.0 specs finalized to the public. After all, where would we be today without USB? Have you ever thought about it? Life would probably be a little bit more complicate
