RE: Raid to Mirror comparison

OK, I'll bite. If I have 4 4Gig drives I have 16Gig total. But won't I have
to eat one of those drives as overhead. Looks like you accounted for it in
the 8.5Gig drives, but not the 4Gig drives. Was this simply a mistake, or is
there something about the 4Gig jobbers I am missing?

Will this be a new AS/400 or are they looking to install on an existing
box ?
What approx. disk capacity do they have (MB).
With the new model 6xx and Sxx series you can RAID-5 the base (Load
source) disks, so you could install four 4GB or 8.5GB drives and have
16GB or 25.5GB usable disk with RAID-5.
With older systems mirroring was often cheaper because you had to mirror
the load source drive.

        Does anyone have any good information on the value comparisions
on raid vs. mirrioring for a small shop?  My client is looking at the
cost vs. benefit differences. 
         
        Thanks,
