From: FF To: freebsd-fs@freebsd.org Content-Type: text/plain; charset=UTF-8 X-Content-Filtered-By: Mailman/MimeDel 2.1.20 X-BeenThere: freebsd-fs@freebsd.org X-Mailman-Version: 2.1.20 Precedence: list List-Id: Filesystems List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 08 Sep 2015 23:15:51 -0000 I'm asking a pretty vague question and I apologize in advance, not trying to troll. The question has to do with whether FreeBSD is using TRIM the same way as recent Linux kernels. https://blog.algolia.com/when-solid-state-drives-are-not-that-solid/ seems to imply that there are instabilities that can occur. Trying to avoid duplicating effort if this has already been addressed or if its a complete dead alley because there isn't a commonality. Thanks in advance! -- FF
