Only write performance to the UFS root filesystem.  I run a system
using a similar approach (though across 3 disks).  My only suggestion
would be that instead of a single 5-way mirrored root, you have a 2-
or 3-way mirrored root and an off-line root backup using the remaining
disks - if you accidently trash your active root, you can just boot
off one of the other disks to recover.
