I'll go with that. Thank you.
I like John's postings... he's rational, and where his solution might not
work for everyone, he usually acknowledges that.
However, did not one of the links posted here state that Google does not
use RAID, it uses replication, except in a few situations where they find
RAID is unavoidable.
As I recall, the "Google File System" is a distributed file system (i.e.
where a particular chunk of data might be one any of a cluster of
computers), and because it replicates each chunk of data onto multiple
systems, you could say it's "application-level RAID". Or, you could say
it does "filesystem-level replication" (as opposed to database-level
replication). See http://en.wikipedia.org/wiki/Google_File_System
