> Overall, any kind of SMART error correlated strongly with disk failure.
The likelyhood of a disk failure going up from an annual 7% to 15-30% in eight month is hardly what I call a strong correlation. 80-90% would have been a strong correlation. 30% leads me to the same conclusion Google had:
keep the disk, but also keep a backup somewhere.
And this conclusion is no different for 0.5%, 7% or 30%. If anything changes at all, the number of backups might.
