M1 activity monitor showing different SSD write reading than system terminal... Apple is hiding something

This kind of goes along with my postulation that the excessive swapping/disk usage exhibited by the m-series Macs is not "a bug", but rather, "a feature".
That is to say, it has been purposely "designed into the system".
But... they'd rather not talk about it.
It would also support [what I believe to be] Apple's total "silence" on this issue so far...

Or your iostat command is showing both reads and writes? Which is very similar to 84.77+42.40=127 GB.
Internet: fake facts prove my baseless conspiracy theory!
Yes, I agree with you that it is a 'feature' which enables the unified memory architecture and efficiency of Apple Silicon helping it to do more with less memory, but I'd argue that it is a bug as this 'feature' comes at a cost. As you might know all SSD's have a certain TBW after which it is prone to fail, so this amount of write over a period of time even though is to increase efficiency might end up failing the system. Thereby making it less efficient than their intel macs that would last for years, but in these M1 macs a drive failure could be fatal as the system now depends on RAM more than before. This is why I say it is a bug..... Open to other speculations😁
I was wrong about the 2nd fact yet you can't deny my 1st fact "1. On intel macs using this code you could see the total data written to SSD since you first started using the device, but on M1 these values would be too huge that apple purposefully disabled it from showing all time ssd write and made it to show data written since last reboot only."
It's exactly the same on Intel and M1 Macs... iostat shows the total IO (reads + writes), as already pointed out by others. Apple is not "hiding anything", you just misunderstood what the numbers mean.
I would kindly ask you to edit your original post to clear up this misunderstanding, or we will have hundreds of "articles" tomorrows with "proof" that Apple is deliberately killing your SSD and does not want you to know it.
A little high but not unreasonable. Unless the MacBook Pro is only a few days/weeks old, a total of 1 TB would be pretty unlikely.
That isn't a statement of fact, 'on M1 these values would be too huge that apple purposefully disabled it' is an opinion. The difference is that since you don't have any way to know why the results on the M1 system are not the same as on the Intel, you cannot state Apple's motive. You can guess, of course, but that also would not be a fact.
I suspect that apple doesn't like users keeping their devices for more than a year or two, so a feature that writes an ssd to death in a couple of years seems more like planned obsolescence than a bug.
And you think the total IO to your SSD is just over 1 TB for the entire time since 2015? It is the amount of IO to the SSD since your last reboot.
Well since it's my mom and 10 year old brother who uses it i don't expect the values to be huge.
Just OS updates alone will have written more than 1 TB not to mention it also includes reads. Why not just reboot it and check again to convince yourself?
An interesting proposition, which seems likely to become the basis for a class action lawsuit in due course. It will be interesting to see what Apple's defence would be.
Perhaps a fair point with iPhones, but there do seem to be plenty of people who have been using their Apple computers for years though, so it doesn't bear up to examination at this point.
I'm not following how the M1 results are different from Intel?
On both my Intel and M1 systems the iostat number is approximately the sum of Activity Monitor's data-read & data written.
From my rMB12:
and from my M1 MBP:
This whole thread is wrong. There is no difference between Apple Silicon Macs and Intel Macs with regard to iostat and Activity Monitor.
