Thank you for an insightful answer.
Now I wonder, why would anyone want to use TRIM feature on a portable
SSD, especially on an encrypted one?
Isn't this feature only increases drive wear, offering next to nothing
as a benefit in return?
I don't use TRIM feature on my systems because of that, and hope for a
firmware of modern SSD will manage everything automatically. Am I wrong?
