from what some google guys have told me at pete's coffee, starbucks, etc. here in mountain view ca where i live, google does not use RAID, they only use ZFS. but that's hearsay and i'm not a storage nor hard drive guy ( i work on RF and uW noise related to materials sorta stuff) so better to ask around some more.

Google has their own filesystem, gfs, designed around large number of cheap servers, where multiple copies are stored and you can lose servers without data loss or interruption.    Hadoop is similar.  While it wouldn't surprise me if they have zfs in some use cases, zfs is not the model for mass cloud installs.
