A lot of that opsec material is very dated back from when density was lower and you had a spinning disk. Do you have any that’s evidence-based that such techniques are needed for flash storage? If anything the opsec concerns are different. There’s very little that would force the controller to actually perform erase of specific blocks (eg the flash could blacklist blocks due to errors). To my knowledge that’s the primary concern, not that the data is still somehow recoverable once erased (which used to be true but I’m not sure holds for modern storage).
