Well... You're probably not 100% active 100% of the time...
Assuming the failure rate of drives is not linear, but skewed toward higher
failure rate after some period of time (say, 3 yrs) then you're more likely to
experience no errors for the first year or two, and you're more likely to
experience multiple simultaneous failures after 3yrs or so.
