Surely a unit with one defective block and a squillion good blocks is
faulty. Sure it is. It has a fault, which is what it means to be
faulty. Spread the wear of that one block over all squillion and one
blocks and you get a much longer lifetime. It seems intuitive that
distributing wear significantly increases time to failure.
