The amortized cost is closer to $600 for nickel disks and $150 for polymer.

Back to the near term : can someone tell me the rough cost per GB and
expected lifetime of the backups our colo uses?  (I would guess $1 and
20 years.)  Are there full offsite backups?

I would feel better if people would help update
