I think my post was unclear. The attack (and rapid wear) were both in the absence of wear levelling (of which capacity variance is a form). My points, which I admit got lost in there: 1) With wear levelling, write amplification doesn't matter much, since you have nearly infinite life in either case. SSDs fail, but only in highly esoteric scenarios due to going over write limits. 2) The write patterns in the paper make no sense, relatively to real-world usage patterns, or what wear levelling is trying to address.
