A much better way is to use the ZFS mirroring capability.  The command
is:

    # zpool attach -f ... ... ...

You could also use:

    # zpool replace [-f] pool device [new_device]

Wait for the resilver to complete.  The result will be a two-way
mirror, in the case of the first command.  Then, detach the small SSD
and try booting from the big one, again for the first command.  The
second command does it all in one operation.  The manual will tell
you more than I can.

Note that I've only done this with both disks permanently installed
on a desktop.  I don't know if it even works with USB disks.
