The "zpool status -v" output was from a Thumper (X4500), slightly edited,
since in our real-world Thumper, we use c6t0d0 in c5t4d0's place in the
"optimal" layout I posted, because c5t4d0 is used in the boot-drive mirror.
See the following for our 2006 Thumper benchmarks, which appear to bear
out Richard Elling's RaidOptimizer analysis:

While I'm at it, filebench numbers from a recent J4400-based database
server deployment, with some "slog vs no-slog" comparisons (sorry, no
SSD's available here yet):
