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. http://www.amug.org/amug-web/html/amug/reviews/articles/sonnet/mac-pro/ 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) Brad -- "Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so." -- Douglas Adams
