Sorry, I'm lame. I was originally curious why my read performance was
less than half of the original posting. I didn't initially realize he
was doing RAID 0 Striping...

I'm still wondering though... does the fact that part of the drive is in
a software RAID mirror affect write performance to the other non-mirror
partitions? Basically, would I be better off adding a third drive for
all Myth-related stuff that is completely independent of my RAID mess?
