Why is that amazing? Does it not make perfect sense to guarantee disks 
for as long as you say they will probably remain free of error? If the 
two were out of sync, then we could conclude the manufacturer either is 
using poor techniques to measure the MTBF or misrepresenting the true 
value. Now, if they extend the warrantee well beyond the true MTBF, 
then they'll be paying for a lot of replacements, and it would be 
foolish or inept of them to do so. If the drives fail long after the 
warranty period, then they could, without additional expense, extend 
the warranty further and appear to their potential customers to have 
great quality products (which their drives do in fact possess).

No matter how cynical you are, business still works best when all 
parties (customers and competing vendors) share accurate and complete 
information about the products and services being bought and sold.
