Here's a screenshot of X-Ways WinHex after TRIM.
On your screenshot I can see additional TRIM files created instead of TRIMming the deleted file. Based on that screenshot your tool fills up the NTFS volume with hidden files and then wipes them. Actually it is a way of trimming (let's call it MANUAL TRIM as you named earlier). But you can do the same with sdelete, you don't need any special tool for that and you could always do that in the past, too.
A few weeks earlier I asked on this forum if I would do the same with SDELETE, why it would be not equal with a manual TRIM? If I fill up the unused space on the NTFS volume with zero and wipe the files on Winhex the result looks the same as if TRIM would work.
Could someone please explain me actually what is the difference between if the controller flushing the NAND chip (TRIM) or I fill up manually with zero with SDELETE?
