It's not all about density. You *Must* have positive retention and alignment. None of the USB nor firewire standards provide for positive retention. eSATA does sort of in some variants but the connectors for USB are especially delicate and easy to break off and destroy. There's the size of the Cat5/5e/6 cable to be considered too. Then you must consider that the standard must allow for local termination, the RJ45 (And it's relatives) are pretty good at this. Fast, reliable, repeatable termination with a single simple tool that requires only a little bit of mechanical input from the user of the tool.

I was looking at a Raspberry Pi board and was struck with how large the ethernet connector is in comparison to the board as a whole. It strikes me: ethernet connectors haven't changed that I'm aware in pretty much 25 years. Every other cable has changed several times in that time frame. I imaging that if anybody cared, ethernet cables could be many times smaller. Looking at wiring closets, etc, it seems like it might be a big win for density too. So why, oh why, nanog the omniscient do we still use rj45's? Mike
