This TRIM technique speeds up the data access process and has a side-benefit of making it impossible for anyone to recover the files erased from an SSD-based Mac. To avoid Mac slowdowns that traditional spinning hard drives often cause, Trim allows macOS to immediately wipe blocks of data that are no longer considered in use - once you delete the files either by emptying Trash or using similar tricks to get rid of the files such as Command + Del or Command + Opt + Backspace. This is mainly because the way how a solid-state drive (SSD) works is different from that a hard disk drive (HDD) does, especially when your Macintosh internal drive uses the TRIM command.
