Hope this info/insight helps. I'd love to switch, but I didn't really have the money for the card then, and now I have less money. I suppose if I ebayed this card first, and then bought a new one that would work out, but yeah, It will have to wait a bit (things are VERY tight right now). So this Intel card, looks like a good option, but how much faster is it? I get 500MB/s read off this SASLP. Probably a bit more now that there's 7 drives in the array. Off of XFS, it gets at least 200MB/s read (the discrepancy between raw and over xfs really bugs me, something there can't be right can it?). Thank you for the suggestion though, I will have to book mark that link. -- Thomas Fjellstrom tfjellstrom@xxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
