2 x 500GB mirrored root pool

I happen to have 2 x 250GB Western Digital RE3 7200rpm
be better than having the ZIL 'inside' the zpool.
listing two log devices (stripe) would have more spindles
than your single raidz2 vdev.. but for low cost fun one
might make a tinny slice on all the disks of the raidz2
and list six log devices (6 way stripe) and not bother
adding the other two disks.
But if you did that, a synchronous write (FUA or with a cache flush)
would have a significant latency penalty, especially if NCQ was being
used.
The size of the zil is usually tiny, striping it doesn't make any
sense to me.
