> You may wear out your (spinning) disks with scrubs more than you do with real workloads. This seems like an extraordinary claim requiring extraordinary evidence, especially since the notion of wear out is only applicable to SSDs (as shorthand for write endurance). I certainly believe that mechanical disks, with all those moving parts, can have their failure rates increased by increased use, but it's not safe to assume even something as high as a linearly proportional relationship, considering which parts move when.
