You missed the point, Gaillo.

Running outrageous numbers of hard drives with multiple levels of redundancy would generate highly useful cross-sectional data on hard drive reliability.

No amount of money will make 100% of hard drives reliable 100% of the time. It can however provide 100% data retention and uptime, which is what you are referring to.

Ah... gotcha.

I doubt they keep most of the drives actually running (powered) though... I'm betting they index them then store them "offline" until needed - particularly the backup copies.
