First what use are the two internal drives that aren't in the disk array?
Someone suggested to WRT them, and I am not familiar with that term.

of my 10 18GB disk configuration. After the sales guy and engineer

that their RAID performs that well with extra large database block sizes.

We are in the process of buying new hardware, and our original configuration
called for 10 18 GB drives in a Hitachi disk array cabinet. We are getting
some sales pressure to change this to 5 36 GB disks. Now I was planning to

Hold on a minute. I run Oracle on my laptop just fine with a single drive.
It would also scream with an EMC disk array attached to it. It really

You'll have to do the math, and that's still not a complete
answer.
By 'math' I mean figure out the maximum throughput of their
configuration version the one you really want.
Also keep in mind that 5 36 gig disks means RAID 5. Being
somewhat familiar with that app, I feel fairly

Although I agree with these recommendations, I don't agree that Oracle
is such an I/O hog. Oracle was designed to perform I/O efficiently
and generally does so. Poorly-written SQL can create an I/O
bottleneck, but it's not the fault of the RDBMS.
