how hard is it to just flip bits on every single available memory? Is it because you have to use the manufacturer's black box controllers and you don't really know if they actually do what you asked?
- daneel_w 2y agoYes, that's exactly what the problem with flash storage is. A single pass of overwriting all nominal storage is pretty close to wiping the entire disk - the spare blocks are limited in number - but with SSDs there's just no easy way to know what may be left behind on eventual bad blocks that have been replaced by spares. So-called "hybrid" HDDs that are fronted by a small SSD to give the impression of faster writes are subject to these complications as well.
