Sounds wrong to me.

The MTF for that many disks would be hours or even minutes ;--)
But then again they would be under warranty. Then you have maintenence
contracts, which can cost a pretty penny. 2 yoyo's a drive sounds like
wishfull thinking, or marketing.
Storage is bloddy expensive, and google would be using fibre arrays I
would imagine and they can cost millions - vendor depending.
But they have obviously thought this through, and its april 2nd so we know
its not bull ;--0
