Trimforce status from terminal copy & paste: This helps ensure that all storage cells are aged uniformly and maximum lifetime achieved. The SSD doesn’t need to immediately delete or garbage collect these locations it just marks them as no longer valid. This results in a reduction of the number of erase cycles on the flash memory and enables higher performance during writes. 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.
