I'm still awaiting official TRIM support for SSDs. Last I checked, that was still a work in progress but coming close to release.

Also along that line, there's also work going on to make L2ARC persistent across reboots (which would be wonderful for starting up VMs hosted on zvols).

I heard that recent SSD s don't really rely on trim so it doesn't really matter, does it?

ZFS needs double digits of free space to be happy. SSDs need double digits of zeroed space to be happy. Overlapping these requires TRIM.

Hey, I'm curious, would you mind turning 'showdead' on and replying to my comment here? I'm shadowbanned on here and would sometimes actually like replies in discussion with interesting comments like yours. Thanks.

You don't need it but you want it.

SSD's don't rely on trim, so you don't need them. It has still impact on performance and longlivety of the SSD. Depending on the usage patterns, the effect can be large or nonexistent.
