I'm curious how much of a performance hit you'd take from running Mast/Slave on a Pri/Sec ATA setup with Linux RAID 1+0 on top? Mainboard is a basic A8V from ASUS: http://www.asus.com/products4.aspx?l1=3&l2=15&l3=68&model=478&modelmenu=1 None of its mine, I am just curious if it makes any sense for a production box. Thanks.
