This results in a reduction of the number of erase cycles on the flash memory and enables higher performance during writes. Why Is TRIM So Important When the OS, (Mac, Windows or Linux) uses TRIM with a solid-state drive, it sends a signal to the SSD every time you delete a file. The advantage of the TRIM command is that it enables the SSD’s GC (garbage collection) to skip the invalid data rather than moving it, thus saving time not rewriting the invalid data.

TRIM will release deleted blocks, It is recommended once enabled do a restart into SafeBoot Mode (hold the Shift key.) What you don't want to do is turn it on and then change your mind a turn it off, which can lead to data corruption. ![]() Optimize Performance - Access advanced macOS.
