I actually mentioned that, but maybe not as well as I should have. I did say 8, 12, and 16 drives in an array will perform similarly.
However, in cases where you are using SSDs for ZIL/L2ARC, vdev spam isn't as big of a factor. In the example I gave I was illustrating the amount of usable storage you could get in the context of having it reliable, not comparing performance of RAID-Z vs non-ZFS RAID.
