What is TRIM？

TRIM is a command for SSDs that tells the controller which data blocks are no longer in use. This allows the SSD to clean and free up space in advance, helping maintain long-term performance and prevent slowdowns in write speed.

Simply Put:

Imagine your SSD as a bookshelf. When you delete files, it’s like taking books off but leaving the spots messy. (TRIM) is like telling the librarian, “These spots are free now!” This helps the SSD clean up in advance, keeping it fast and organized over time.
