software raid and multiple cores

Hi Thanks to those who contributed to a discussion on software raid recently, it changed my mind about the universal desirability of hardware raid cards. So now I'm intent on building a sw raid based machine, but mostly am interested in performance under disc load. Basic question: given a number
