[TowerTalk] Long Term Connector Reliability Re: TowerTalk Digest, Vol

[Grant Saviers]

And automotive buyers are totally serious about "better than six-sigma" 
quality & infancy failures.  Six sigma is 99.99966% good.

Another fascinating stat is the Hitachi data center disk drives have 
around an 800,000hr MTBF.  That is 91.3 years.  Sounds great unless your 
google cloud site has 20,000 of them.  Then statistically one fails 
every 40hrs.  One strategy is to have enough redundancy that failures 
are ignored since the whole server blade will be replaced every few 
years and thrown away.
