Depends on the CD.. the Green one's are the cheapest, and they're only
rated for ~20 years (tip: don't leave near direct sunlight, it fades them
and the data becomes unreadable, as happened at home)
Silver/Blue are next, they're allegedy ~40-50 years.
Gold are the best and most expensive and are rated for ~100 years, but
finding the actual gold ones is a bit harder because most people
are buying the cheapest ones possible.
