When both mirror drives fail the same way

• jqpabc123 18d ago
  Never use identical drives in a mirror. The same model is Ok but the exact same age is not. I always try to "engineer" a controlled failure by using one old and one new drive. But none of this can defeat human error.

    It was something I never thought about until I lost my first drive. And agreed on human error, I killed the second drive by running the second scrub.

      I start with 2 new, "reliable" drives. After a couple of years, I replace one drive with a new one. Keep the removed drive to use for offline data backup. Run until failure or 5 years, which ever comes first. Then replace the oldest or failed drive with a new one. Wash, rinse and repeat.
