SO, with 100 drives the propability is 100%? It just don't work that
way, sorry.

The discussion is about MTBFs. If a single drive has an MTBF or 10000
hours and you have 100 drives in the system then the MTBF of the system
would be 100 hours. That doesn't mean that the system will fail once
every 100 hours like clock work. It just means that on average you would
see a drive failure every 100 hours.

That's a pretty amazing statistic, but after the 2 or 3 duds died the
other ones would last for awhile before they started to.

I'm just using 10000 hours as a nice round number to explain the math. I
don't know what the actual MTBF number for any particular drive is but I'm
pretty sure it's better than that.

That is very fascinating, but the probability still doesn't add up to
100% does it?
