Linux "md" raid, and Linux SATA drivers :) One caveat: you *may* have to create "one disk RAID-0" arrays of your disks (which is equivalent to the single disk), in order to make the SATA controller boot from the disk. So, with two disks, you would create two RAID-0 arrays, each containing one disk. Silly really, but at least I had to do this with the Promise TX4. Other than that; Standard Linux SATA drivers + Software RAID + LVM2 is a beautiful all-open-source solution for cheap flexible and reliable storage - my mom is using that ;) -- / jakob
