I have 4 160 GB SATA drives and a Raid controller that does Raid 1, 0, and soft 5. I also have a 5 pack of DVD+RW's that I am dedicating to backups. My original plan was to have one drive with a partition of 20GB where windows would sit, and the other 3 drives used for soft raid-5. But then I would have 140GB of just blah space on my primary drive. I never made it a habit of backing up so I have no idea what the best method is of doing it is. I have Norton Ghost 9 and a boot disk that can boots up in dos that can burn the img on DVD's. I guess the question is, what would you do? Also is it bad to have a 400+GB partition?
