As has been mentioned in another thread, RAID 1 pairs with LVM is pretty safe and flexible. The disadvantage is when adding more capacity, you have to add drives in pairs.
With RAID 5, you don't have to add in pairs: just add a drive when you want to. If one drive fails, *all* your data is still safe :)
The disadvantage is that you may not be able to utilise the entire capacity of each drive (unless they're all of equal size), but hey, nothing's perfect!
