I am using an SSD with Solaris Express. Solaris Express does not have TRIM. I doubt newer versions of Solaris has TRIM, but OpenZFS might have TRIM?
My question is this. I am going to reinstall Solaris 11.1 on the SSD (I have bought a new PC). My SSD has never been TRIMed, so I should TRIM the SSD I guess. But, if I reformat the SSD with ZFS, do I still need to TRIM the SSD?
