Hey, I've got a rock64, USB case with a JMS578 and a Samsung 860 evo 1Tb (ext4) in it which I'm trying to trim.
I've tried it with fstrim and the wiper.sh script from here, both without success. The JMS578 is running v173.01.00.01 from odroid.
After verifying that trim really doesn't work with a method like this , I'm now kinda worried about my drive health long term as even garbage collection doesn't seem to help here (because of ext4?). As people are successfully trimming with the same setup but with a 850 evo instead, I guess the problem lies here.
Now my question,
