Quotes 1.2M (136 Years) Hours MTBF. Now as *I* understand that, they are saying the average drive will last that long? So If the average is 136 Years, I am wondering what their actual failure rate is and what that makes the minimum and maximum and how they actually test that :) 

I am thinking that if they have ONLY 50 drives a year fail in the first 2-3 years, then some of these drives must be lasting a very very very long time to bring the average to 136 years. Or has my math failed me?
