looks like my mistake - or simply a shortcut that made statement
it should be added:
ZFS can be installed on partitions and share disks with other things, but
the performance will be bad.
ZFS - contrary to every other filesystem that use FreeBSD disk I/O
scheduler - does it's own I/O scheduling, so it assumes it's the only user
of physical drive.
if both non-ZFS and ZFS filesystem will share the same disk AT THE SAME
TIME - there will be a lots of thrashing.
