    Having had an issue with 2 powercuts in quick succession meaning my Mac Pro was unbootable I am looking into the software RAID built into Snow Leopard. I know it doesn't replace backups and I got my data back ok from backups.

    My system disk is a 1GB drive, could I purchase a 2nd identical drive and mirror across that without having to do a system re-install?

    What would happen to the Bootcamp partition which is also on the same drive.

    Taking my thoughts one step further, if I bought 3 more 1TB drives, could I create software mirror sets, and then stripe across those, which should give me some performance and reliability gains?

    Thanks alot,

    Greg

    No if you're striping the disks into a single volume, you'll have to move your data elsewhere, create a single RAID volume from the disks, partition it how you want, and then move the data back.
