How do I prolong the longevity of my MacBook's internal SSD?
Solution 1:
I'm speculating that kernel_task's write may be a result of swap memory, so your 'fix' might be to not run so many things at once.
As to the rest, I'd simply stop worrying about it.
My oldest Samsung SSD has been running 24/7 since 2014 & has yet to show any sign of age. In fact the only failed SSD in the building was a cheap generic 128GB drive which gave up the ghost after about a year of not particularly hard work. All the others are still going, various ages from 1 to 6 years.
