I am not sure about the ZFS implementation on FreeBSD but regarding ZFS on Linux (ZoL0 there is a patched version which supports trimming, and I have tryed it (on Linux RHEL7). I had a positive experience with the Intel SSD DC S3510 series 480GB. They are discontinued now but I have seen them on amazon at $280, they are enterprise class, and I never needed to TRIM the FS on them, I Really wrote a lot of data on them, and they are SATA. I also bought a bunch of them second hand which were used intensively and they still run fine even if they have been used a lot before me. I used them as boot disk and system disk on OpenBSD (sparc64). Rick > >> On 5 Jun 2020, at 11:23, Riccardo Veraldi <[email protected]> wrote: >> >> you may opt for enterprise level SSD disks.
