Personally would recommend a couple of external/removable hard drives; one for at home and one to keep somewhere else (work/friends/family). That with your local (home pc) copy of images gives you three copies for plenty of redundancy. Just keep updating these until you run low on space and you can replace with a bigger/newer drive. So cheap these days and avoids any worries about media degradation and the hassle of managing numerous discs, plus quicker to access/update when needed.Is there a certain type of CD or DVD that would be best suited to saving pics to that has the best shelf life etc?
Now its nearer 20p/gb!
