A new major feature is the "super speed" bus, which provides a fourth transfer mode at 5.0 Gbit/s. The raw throughput is 4 Gbit/s, and the specification considers it reasonable to achieve 3.2 Gbit/s (0.4 Gbyte/s or 400 MByte/s), or more, after protocol overheaded.
When operating in SuperSpeed mode, full-duplex signaling occurs over two differential pairs separate from the non-SuperSpeed differential pair. This results in USB 3.0 cables containing two wires for power and ground, two wires for non-SuperSpeed data, and four wires for SuperSpeed data, and a shield that was not required in previous specifications.
To accommodate the additional pins for SuperSpeed mode, the physical form factors for USB 3.0 plugs and receptacles have been modified from those used in previous versions.
First post in a month. Thanks for getting these up Kyle. If you are legitimately interested in technology, why not spend more time learning about it.
ReplyDeleteIf you have a suggestion for a different publication (ie something other than Wired), feel free to suggest it. But, it needs to be a legitimate publication, electronic or otherwise.
Most of your posts seem to be about new technological breakthroughs. Consider adding what you think the impact of such breakthroughs might be at the end of your posts.
