The problem with this question, as I see it, is, it's hard to understand what the person is talking about.
I admit that this seems to be because I simply don't know enough about the topic, but then maybe this is the wrong audience for the question in the first place?
Nevertheless, if you want to improve the question to make it more clear what is being asked, then I'd be happy to reopen.

Funny thing, it is because electrons are captured in the oxide layer of the cells. This slows performance, but can be "reset" by applying larger voltage in the opposite direction of the cells to remove the electrons that block the cells.
Read that, then read it again, then read it until you understand why the question was closed :P
In all seriousness, what the user claims there sounds wrong. Which might be because he doesn't know what he's talking about. Which isn't surprising, cause neither do I.
- How are electrons captured in oxide layers?
- Where are these oxide layers in the SSD?
- How do you apply a voltage in a direction?
- How do you determine the opposite direction of a charge?
I have no clue what process he is trying to describe here and why he thinks it has to be explained on this level.
And then he asks for a software hack... What is that even?
The question is horrible. It could be made into a proper question that asks "What is the TRIM feature and how do I enable it?". But, in my opinion, it's not even clear if that's what the user is talking about. So you can't even edit the question in that regard.
