Re: how to enable trim for an external encrypted SSD?

You could ask the LUKS developers to include an additional flag in

opened with discards allowed by default - to maybe solve this in the

as they do discourage the usage of TRIM in LUKS because it weakens
possible security guarantees somewhat.


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?

With kindest regards, Alexander.
