Anyone here have experience with RAID

Thats what i was hoping for, and then by adding a 3rd disk the parity would happen.....BUT i guess things don't work that way

Basically, in my head you can add disks to a raid array without needing to reformat the array correct?, the controller will re-optimize everything itself. Thats what i thought would happen, that by adding a third disk my raid controller would realize that i has room for parity and then it would just work

I'm going to have to end up buying a new HD then, If i combine every hard drive i own and put my data on it, I'd barely reach 700GB and thats on ~5 drives....very risky and inefficient
