not just samba writes to either of the data disks from the network via
samba or scp are painfully slow. Reads from the box to the network are
fast. Copying files from one disk to another one the server are fast.
Taking the disks out of the equation entirely: does scp'ing a file to
/dev/null run fast or slow?

The NIC is sharing IRQ 9 with the USB controller, can you select another
IRQ for the NIC in the BIOS? Especially if you can select a non-shared
one?
Good suggestion Darren,
I thought you might have hit upon it there. I remember a problem from
way back when a promise raid controller card was fussy about which pci
slot it was in. Anyway I tried moving the NIC to another slot and also
manually set the irq in the bios to 12.
Neither made any difference though....
