I wonder if in this case it would be beneficial to slice i.e. 90%
of an SSD for use in ZFS pool(s) and leave the rest of the
disk unassigned to any partition or slice? This would reserve
some sectors as never-written-to-by-OS. Would this ease the
life for SSD devices without TRIM between them ans the OS?

Curious,
