If data redundancy is built into the storage - lots of extra bits to allow for recoverable data - then you'd get the durability that Amazon quotes. You're guessing that they store on tape. That might be true but for long-term storage tape isn't an ideal candidate. However it's stored, Amazon says they have a technology, or a growth path for technology, that will keep your data alive and available for the indefinite future. Looks pretty attractive to me.
