I recently read a very nice review of the 7042 on a Sonnet card in a Mac and they were pulling over 
700MB/s using SIL port multipliers in a 4 lane slot. They managed over 1GB/s with 20 drives across 2 
of the cards! I've heard some unkind things about the SIL cards bandwidth, but these Marvell jobbies 
look very nice.

I've half a mind to order a couple of these and some PM's to play with. Shame the only PM's I can 
seem to find that do what I want are $85 each from addonics (I need 5 of them)
