Are there trends for AFR by drive age? ie. for a specific drive or manufacturer, what is the failure rate for drives that have been in use n years? It'd be interesting to see how the failure rate go up/down as they get older.

Electronics typically follow a "bathtub" reliability curve. You'll have a large number of early failures (unflatteringly called "infant mortality") then the curve levels off for a long period of time, and then starts rising again as the items start wearing out.

It'd be interesting to see if BackBlaze sees this in their drive populations.
