When it comes to predicting stats; agreed.
This is the other way around; historic data on how $device *has* behaved.

Something which can help with replacing early etc. In our case: a certain
model HDD was reported with a high error rate. Sure enough, once one of
them failed, 2 others were quick to follow. Thanks to the warning from this
data, we were prepared and could simply swap the disks without any downtime.
Oh yeah, the replacements were from the same brand, just another model.
Superstition? Perhaps, but so far, so good ;).
