Switched to AHCI and now looks more plausible:
kstat.zfs.misc.zio_trim.zio_trim_bytes: 2173466624
kstat.zfs.misc.zio_trim.zio_trim_success: 13244
kstat.zfs.misc.zio_trim.zio_trim_unsupported: 0
kstat.zfs.misc.zio_trim.zio_trim_failed: 0
I'll report back if anything unpleasant happens. Thanks to all for this.
