Somewhere I read, for maintainance of an SSD all it's cells should be read
from time to time like this
sudo dd if=/dev/DEVICE of=/dev/null bs=8M status=progress
Where did you read that? That seems like a huge waste of time.
As far as I remember, the idea behind this suggestion is to help the SSD
firmware detect bad blocks or cells early on and to mask them out. Of course, a
good firmware with it's wear leveling algorithm
(https://en.wikipedia.org/wiki/Wear_leveling) should do this by itself.
