"use the girth" -- I'd love to pretend that I knew what this means but
someone might call me on it.  What does it mean?  Each drive is 36G.

On my NT Quad Development box I have 9x2 Raid 1 for OS/Oracle Files.

Then Raid 0+1 for the 6 drives for data.  It isn't perfect, but works good.
If you do raid 0 with 6 drives, make sure you look into a good stripe size
so you actually use the girth.  Otherwise 0+1,1+0 may be a better option.

We're setting up a development box that will have a number of instances on
it.  We won't need any backup, since we can easily re-create the databases
from testing instances.

I'm planning on implementing the disk storage as RAID0 - a single logical
volume stripped across all the drives (6), with the stripe size set to the
OS (Win2K) block size.  We will only have 4 or 5 developers on the box at
any one time and I want to maximize IO utilization.

Any "heads up" here?
