In order for TRIM to work its magic, two conditions have to be met first: That's why TRIM is so crucial: It makes sure that your SSD performance doesn't degrade with use, and keeps it (nearly) as fast as new. That way, your SSD is able to write data to that marked space as if it was brand new and skip the cumbersome deletion process. but in addition, a TRIM command is sent to wipe that marked space clean.

Here's how SSD TRIM saves the day: When you delete a file from your SSD, the operating system will still mark the file space as "not in use". This awful situation is compounded by the fact that solid state drives are only able to delete data in large 512 kB blocks so this slows down the entire overwriting process even more. A traditional hard disk drive is able to overwrite data in one single operation, but a solid state drive first has to erase all data in this "not in use" space before it is able to record the new data.
