I'd use the extra SATA port for an ssd, and use that ssd for some
combination of boot/root, ZIL, and L2ARC.
I have a couple systems in this configuration now and have been quite
happy with the config. While slicing an ssd and using one slice for
root, one slice for zil, and one slice for l2arc isn't optimal from a
performance standpoint and won't scale up to a larger configuration, it
is a noticeable improvement from a 2-disk mirror.
I used an 80G intel X25-M, with 1G for zil, with the rest split roughly
50:50 between root pool and l2arc for the data pool.
