How does powering on an ssd help keep the data? Can it refresh without causing wear equivalent to a rewrite?
Edit: Apparently erasing is what causes wear, not writing
AFAIK, an ssd uses different amounts of charge per transistor to store a 1 or a 0. An unpowered ssd would seemingly eventually lose that charge signifying the 1 or a 0, and thus lose the information it represented.
Haven't looked into that thoroughly though, so could be totally off base.
