And then you have to add overhead, addressing, error correcting, ack/nak
messages, etc.
Only hubbed Ethernet uses CSMA/CD; switched is full-duplex. I've
benchmarked over 95 Mbps using generic consumer cards and switches,
although that was card-to-card (netperf), not disk-to-disk. It's not
that hard.
