I would recommend getting a hdd bigger than 80gb to back up your stuff, that way you have room to add more to it in future back ups and dont run out of space. Maybe like 120gb will be good.

If you want to use RAID, you need 2 hard drives. You can set them up with RAID 1(Mirroring), this enables you to have 2 exact identical hdds for ultimate safety storage. however, if you have 2 120gb drives, you only actually have 120gb of storage because data is written to them simultaneously . If 1 of them ever dies, you still have an exact identical copy on the other drive!
