Plagiarizing, or representing someone else's ideas or words as your own, will cause problems for people in any stage of life. Students get flunked for it and it even cost Joe Biden a shot at becoming the US President in 1988.  Avoiding purposeful plagiarism is straightforward, but to avoid plagiarism committed by accident, you should restate information several times to verify that you've put it into your own words and always cite the original source of that information so that you give credit to where it's due.
TRIM is a SATA command that enables the operating system to tell an SSD which blocks of previously saved data are no longer needed as a result of file deletions or volume formatting. When an LBA is replaced by the OS, as with an overwrite of a file, the SSD knows that the original LBA can be marked as stale or invalid and it will not save those blocks during garbage collection. If the user or operating system erases a file (not just remove parts of it), the file will typically be marked for deletion, but the actual contents on the disk are never actually erased. Because of this, the SSD does not know that it can erase the LBAs previously occupied by the file, so the SSD will keep including such LBAs in the garbage collection.
