My situation can scarcely be unique.
The MTBF is a statistical measure or prediction of the behavior of a
population of drives (not a single drive!) during the design life
(typically five years). The MTBF rating of drives you purchased 15-20
years ago means absolutely NOTHING at this late date. If the drives
keep working, that's great, but you don't have any particular basis for
expecting them to do so for any length of time.
