I saw a couple of surprisingly inexpensive 10GB switches on ebay last night (though I'm too broke to get one this month ). Now I'm confused about cabling. I see there's a whole variety of different connectors, apparently depending at least partly on the physical cable (fiber optic, copper, etc.) selected. I was hoping for something that would simply be backwards compatible and use RJ45 and Cat6 (or Cat6a) but, apparently, it's going to be more complicated than that.

10GB is appealing to me because I often move lots of data around my system and it would be nice to accomplish in seconds what currently takes minutes. I may have to wait, though, until the various standards shake out and a "preferred" one emerges. Then again, my first LAN was 10 Mbs, so I shouldn't complain about my 1 Gbs setup.
