I think tho, that you give it some bias not testing the best configurations for Linux SW raid. For example raid10, the f2 and o2 layouts are faster than n2, and you don't know if Adaptec has some kind of improved layout. It would be interesting if you could enhance your article with benchmarks on raid10, f2 and o2 layouts. I think they would outperform HW raid, at least on input. And I would like to see how they perform on outout and rewrite, with ext3 and xfs. We do have some tests, but many of them are without a file system layer. I would also welcome test with mobo HW RAID - Many mobo's today come with some HW raid functionality, and many people would be in the situation of whether to choose a HW or SW configuration. best regards keld -- 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
