This is what happens to a file when you delete it from your SSD
Deleting a file on an SSD isn’t as straightforward as it looks.

the OS only removes the reference (or pointer, in programming lingo) to that file from the file system index.
SSDs don't overwrite data like traditional HDDs
Unlike traditional HDDs, SSDs use NAND flash storage, which organizes data into blocks and pages. This storage structure plays a key role in differentiating how SSDs store and erase data in comparison to HDDs
Can you recover deleted files from an SSD?
