arstechnica.com— The Higher Speed Study Group has made a decision about how the next generation of Ethernet speeds will be standardized, and for the first time, a single standard will comprise two very different speeds.

1g connections are the norm in our data centers. Equipment with only 100m is basically obsolete for us now. The network I administer is running a full 10g backbone across the US and Europe. We already have to balance a lot of the traffic over those 10g links and we're pretty anxious for 40g (oc768) and 100g connections (even if they *are* going to cost absurd amounts of $$.) We're very much not the first either. A number of internet exchange operators (AMSIX for example) have been crying out for years that they need 100g to use in trunking exchange switches together. From the standpoint of combining the 40g and 100g speeds into a single standard, I'm all for it.
My server to PC link sustains about 70 MB/s. Not bad considering that my disk array maxes out at about 85 MB/s, so with processing and protocol overhead, it isn't bad at all.NOTE: Above in Bytes, not bits. Multiply by 8 to figure out in b/s.
Ethernet is a communications protocol, not a cabling standard. Before Gigabit Ethernet over copper became commonplace, it used fiber links instead. Just like this one.

I'm something of a bulls**tter myself, but occasionally I enjoy listening to an expert. Do carry on...

Yeah... you'll probably want to rip out the copper and put in fiber instead.
