Which "the hybrid" are you talking about? There are several of them  
on the market. Since you're equating "estimated life" with MTBF,  
where do you get the MTBF data? What are the criteria for that MTBF  
figure?

Unless you can point to an accredited source of information  
publishing this figure and the criteria by which it is defined, it is  
worthless noise.
