In my experience, the issues that take 80% of your time are the unexpected edge cases, not the easy fixes.
Swapping drives is basically the easiest fix. The issues that cause the most problems are the hard to diagnose ones like the faulty RAM that flips a bit every once in a while or the hard drive controller that triggers an driver bug with weird behavior that doesn’t show up in the logs with anything meaningful.

Sure, but realistically, how often does this really happen? I have probably replaced 3 or 4 DIMMs over the past few years. Hardware is very reliable these days.
