I was some time involved with mtbf calculations (the milxxxxx norm 
from the us air force). 
It is not easy to make 100.000 with electronics (solder points, ... 
and specially ASICs). 
I always wondered how the hardware (3000...7000 spins(?) per minute, 
times 60 minutes per hour, times 150.000(!) hours!) can make that. 
Sure, Server discs can do that, but pay attention using "normal" or 
notebok drives.
