Google published a study a number of years ago, based on statistics they gathered of drive performance in their enormous collection of servers over many years.
One of their conclusions was that hard drives tend to have a useful life of three years: the odds of catastrophic failure were very low for the first three years, and after that the odds start climbing. Based on the statistics they gathered, they recommended a policy of replacing drives every three years regardless of whether they're failing yet. The idea is that disks are cheap these days, and the cost of losing data far outweighs the cost of replacing drives before they fail.
