Amazon has employees as well, yes? Employees with access to data centers? Employees that may be convinced to make some "mistakes" in the disposal of old disks combined with the early replacement of a few specific drives?

Of course this is very hypothetical and it requires the attacker to know what disk in what rack to target, I'm not saying it's the most likely scenario, I'm saying it can be avoided by flipping a switch and paying a few extra dollars so I'll keep it enabled.
