Nope your misunderstanding the problem. Of course I understand how to make sure I don't lose data. So instead of thinking I am an idiot, you should reread my post. The problem is that my hardware based on my usage pattern has a short life and I don't agree with Apple's need to make throwaway computers just to save a few cents and forcing me to buy a new computer every 2 years.
So Apple should of course make the glued together plastic cased cheap low weight low performance products for the masses. But all I am asking is for them to also make at least one Pro laptop that is serviceable for RAM and SSD. Something that people that demand more from their computers can use for more than a couple of years. I would gladly pay for that, if the design was thermally stable and did not throttle after a few seconds of processing.

Maybe, looks good for posting, but there is nothing is system information that I could find in a current iMac. Maybe instead of just grandstanding you might publish some links so I can learn.
Here is a thread from Jan this year
https://forums.macrumors.com/threads/2017-ssd-life-expectancy.2104004/#post-25771428. No one responded with Apple SSD specs. First without Apple SSD specs no amount of data read and write quantities make any sense. You sure you know anything at all about SSD life calculations.
