Ah, indeed, but 'external data transfer rate'. I doubt that's a

Sure, but where are you going to get a PCI-express controllers from? 
The 3Ware thing is PCI-X - should be enough though. </smartarse>

If you're looking at 3Ware and 3Ware claim 380MB/s RAID-5 writes are 
possible, I'd say "ask them".
