Unpowered SSD endurance investigation finds data loss and performance issues

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.

Apparently

SSD's endurance rating is calculated based on how long it can store data if left unplugged after a certain amount of data has been written, hence the importance of this testing.

That said I thought it was more of a byte write life for SSDs.
