> Failure on spinning disk HDDs is comparatively random.
comparatively, yes, but when averaged out over a large number of hard drives it definitely tends to follow a typical bathtub curve failure model seen in any mechanical product with moving parts.

early failures will be HDDs that die within a few months of being put into service
in the middle of the curve, there will be a constant steady rate of random failures
towards the end of the lifespan of the hard drives, as they've been spinning and seeking for many years, failures will increase.
