OMG, drive prices are insane!  Just 4 x 2TB SATA drives cost more than 
the rest of an entire 2U system.  We are considering getting Desktop 
drives temporarily and waiting for Thailand to rebuild before filling 
out the remainder of our disk arrays!

We are thinking now to just get 4 nics.  2 bonded for the storage 
network and 2 bonded for the Samba interface to the LAN.  That outta do 
it.  I think your math on the drive speed vs network speed is right.
