Actually, you have all disk failures at the end of the disk's life. :-)
I think you're referring to the so called "bathtub curve" failure rate (named for the shape of the graph), where it's generally observed that the failure rate is high at the start and end of the expected disk life. Here's a hokey ASCII graph:
failure |* *| rate |* *| | * * | | ********************** | 0 |--------------------------- 0 age of unit Age
