It clears all data to reduce the time of reading and writing. But a quick format won’t. When you delete data it isn’t really deleted, it is just marked for deletion. Next time, when you rewrite data to that block, the reading and writing times would increase. That would reduce SSD lifespan since it has limit read and write times.

Nevertheless, a quick format is good enough if you just want to reinstall your operating system to your Crucial SSD because a Quick Format will trigger SSD TRIM for the entire disk.
