There's a blog entry about a possible problem with some Samsung SSDs when using trim. https://blog.algolia.com/when-solid-state-drives-are-not-that-solid/ Up to now this problem was only spotted under Linux and was not confirmed by anybody else yet. Nevertheless, I thought it might be of interest to one or another here. Since Samsung SSDs have been recommended a lot in the past. Perhaps it's a prudent move to disable trim — if you enabled it — for Samsung SSDs for the time being.
