Oooh good point. modprobe ehci-hcd seemed to speed things up, the last gigabyte went by at a clip of 1.4mb/sec. It seems it was getting around .8mb/sec before. An improvement, but nothing earth shattering.

It has gotten the server they're being transfered to up to a load average of around 6 and has the cpu bouncing back and forth between 10-90% system. Looks like it's the raid array that needs work at this point.
