    I have no issues with my Trim enabled Crucial SSD, But i would like to keep it running in tiptop shape. What does Erase free space in disk utilities do?

    Depending on certain conditions you might see a minor, minor improvement (like if your SSD is nearly full).

    Erasing free disk space

    When you delete files by emptying the Trash, Mac OS X deletes the information used to access the files but doesn't actually delete the files. Although the disk space used by deleted files is marked as free space, deleted files remain intact until new date is written over them. Because of this, deleted files can be recovered.
