Cool! BTW - based on the above benchmark page, I just immediately ordered 2 x of the Areca 1220 SATA controllers ( http://www.areca.com.tw/products/html/pcie-sata.htm) so that we can compare them to the 3Ware 9550SX that we've been using. The 3Ware controllers have been super fast on sequential access, but I'm concerned about their random IOPs. The Areca's aren't as popular, and there's consequently less volume of them, but people who use them rave about them. - Luke
