Alright, a few months ago, I got a Samsung 860 EVO 250GB. All was going well until recently, when it started being a bit slower than usual, I ran a test and saw that the read speed was a lot slower (supposed to be 530 ish, only 391.). I tried running Samsung's error checker and chkdsk, none said there were any errors. I also trimmed the SSD, there is around 130GB free of 250. Any possible solution before I send it to Samsung for repairs?
