''I carried over my answer from your other post here:''
Lets think this with something more tangible!
Hopefully you have a paper shredder to destroy your papers. So, if we go back in time the first generation of shredders merely made strips of the page so if I only did one page I could easily take the strips side by side and arrange them back together quite quickly and with some tape reconstitute the page! Now that's easy! The only way this gets harder is when many pages are shredded and they are uniform if you have a few yellow or red pages they could be pulled away and bingo! They could be put back together!
The next is when the cross-cut design came out as now instead of strips we now have smaller pieces! So if we do that one page again while much harder it too can be reconstituted! In fact a person only needs an OCR program and a bed scanner to let the computer do the grunt work!
For most, this is all one needs as the needed gear and skills are beyond what one would apply if you where not a government agency trying to get dirt on you.
This is what I use for my bills and I make sure I bag up a good mix of stuff and as big a bag as I can. This makes it so hard no one will do it!
Still not the ultimate in safety! So let's get to the most secure way. If the paper is dyed so you can't see the writing then you've made the task so hard its just not doable or lets just burn the paper! So all you have is ashes!
So as we can see we have three levels of effort Now lets apply the three with the drives:
● Level 1 - HDD
● Level 2 - Plain SSD
● Level 3 - SSD with full encryption via T2
So clearly if you want full destruction you want ashes Level 3 is the answer. Nothing but NOTHING will be scrap able from your drive.
I have not heard of anything about APFS file system being breakable. Besides its not the file system its self, it's how the data held within it is dealt with.
Think of it this way an envelope that holds the piece of paper is not the risk its the exposure of the piece of paper held within it. So having a bucket which is holding that page I metaphorically shredded above, which is safe? A pile of ashes!
