November 29, 20223 yr I just got two Samsung 870 QVO 2.5" SSD and set them up in a new pool. I'm just curious if the trim function will be run automatically on the new pool just like on the original cache pool? Or do I have to do something special to trigger it? Also, they are set up in a BTRFS raid1. Will trim be performed on both drives?

November 29, 20223 yr Author Aha! I did not know that. But now I'm confused because I don't see the dynamix trim plugin installed anymore. Did that get uninstalled in an upgrade? I do however still see SSD TRIM Settings in the Scheduler: I thought that was part of the plugin actually. So do I now simply disable the TRIM scheduling?
November 29, 20223 yr Author Thanks! I guess I will just go ahead and disable the scheduled trim then.
October 11, 20241 yr Hello all, apologies for resurrecting an old thread but thought I should ask these questions here since it's quite related. I have several m.2 nvme SSDs in XFS format as well as a couple of 2.5" SSDs in btrfs format. Both 2.5" SSDs already have autotrim enabled in their respective settings. One of the nvme SSDs have autotrim enabled while the other two don't. These settings were all set automatically by the system. My questions are: 1. Should I enable autotrim on the other two nvme SSDs? 2. If autotrim are enabled on all SSDs, do I need to enable TRIM schedule under TRIM settings? 3. What would be the difference between autotrim vs trim that is scheduled via trim settings? If there is a difference, which would be a better one to use? Thank you

Typically yes. 40 minutes ago, aquariuz23 said: If autotrim are enabled on all SSDs, do I need to enable TRIM schedule under TRIM settings? Still a good idea, since sometimes some extra sectors are trimmed. 41 minutes ago, aquariuz23 said: What would be the difference between autotrim vs trim that is scheduled via trim settings?

Recommend both, I think I remember reading that auto trim can is some cases cause a performance penalty, but possibly only in some extreme use cases, where the SSD is constantly being used.

As always, appreciate your clear and to the point answers! Thank you.
