An anonymous reader writes "My kid is now 1 year old and I already have 100G of digital video (stored on DVDs, DVD quality) and photos. How should I store it so that it's still readable 10 to 20 years from now? Will DVDs stil be around, and readable, 10 years from now? Should I plan for technology changes every 5 to 10 years (DVD->Blue-ray->whatever)? Is optical storage better, or should I try to use hard drives (making technology changes automatic)? And, if the answer is optical, how do you store optical disks so that they last?"
