Which approach to SSD?


The first article is specifically about "raw" solid-state memory. It's therefore not applicable for your typical (desktop/server) SSD. These drives contain firmware that already handles wear balancing, so you don't need to do this in software using e.g. MFS.

But this has another consequence: It's close to impossible to reliably "wipe" data from a modern SSD. Therefore, I suggest to go for full-disk encryption from the very beginning. Then, throwing away your key is effectively a perfect "wipe".
