See if I can make this make sense. I previously had 2 160gig HDs set up RAID 0. One drive failed and I reformated the working one and reinstalled windows and all my apps. I just purchased 2 250gig HDs to set up RAID 0 (again) and a backup 500gig HD to mirror the RAID 0 configuration. Can this be done somewhat easily? Does anyone see any problem with this?
