MTBF figures for hard drives (and possibly other things) are quoted
in terms of analysis of large numbers of that model. The item is
rated for 2 years of use.
What they are saying is that if you got many of these items and ran
them simultaneously for 2 years then you should get 171 years
aggregate service out of them before any of them developed a fault.
Or if you ran one item for 2 years then replaced it and kept going,
it should be 171 years before you had a failure inside the 2 years
of any individual item.
Cheers,
Andy

Q. How many mathematicians does it take to change a light bulb?
A. Only one - who gives it to six Californians, thereby reducing the problem
to an earlier joke.
