The drive doesn't mechanically fail because it's build to work under high load. It can't be thermal because drives would slow down if they get too hot. It's not electrical because the drive doesn't die. So what is it then?
This statement makes no sense. The theory here is that drives don't experience stress, because they are "designed to work under high load." This is simply untrue. Are they "designed to work under high load", sure, whatever that means. But that doesn't change the fact that higher loads create higher stress.
My car's engine is "designed to work up to the red line". Whatever that means. But running the car near red line creates a lot more stress than running it at slower speeds. So engines running near red line regularly die much earlier than ones that do not. And they are mostly likely to die when at their highest RPMs.
Basically you are missing two key facts. The first that designed to work under high load is a meaningless phrase, it tells us nothing other than that some stressful situation is planned for, but failures are planned for, too. So that is not useful in determining anything else. And the second is that higher stress is higher stress regardless of what the drive is intended to handle.
Otherwise, drive failures would be impossible, since no drive is "designed to fail." Since drives do fail, we know that your statement doesn't indicated what you were saying.
If we look at the mechanical stress a rebuild is not so bad because it's sequential reading and writing. The disks are spinning regardless if you are reading or writing or doing nothing so that makes no difference. And the arms don't have move all over the place when you're doing sequential block operations.
But what I was implying is that the second drive doesn't fail for a mechanical reason because that would be the end of the drive. Isn't that your experience as well, that you end up with bad blocks but not dead drives?
