I'll stick with the 3 year life cycle of the system followed by a hot migration to new storage, thank you very much.
Once again there is a fixation on the idea that computers gradually degrade over time and that simply replacing the hardware before the expiration date (like a bottle of milk) will save the data. I recently took an old Sun system out of service that was approaching 12 years on the same disks with no known read errors. The Sun before that one was taken out of service after 11 years with no known read errors. Lucky me.
Various papers I have read suggest that degregation is in fits and bursts and contrary to what one would expect based on vendor specifications.
