Dennis, to tell the truth, writing in oracle is not a big problem, as long
as the redo files are not on RAID-5. Everything else can reside on RAID-5
without a visible performance impact. Second, RAID-5 vendors like EMC and

Mladen - I would propose another theory. Please consider this rant for

astonishing piece of information and if it wasn't coming from you, I'd
dismiss it as yet another conspiracy theory.

...Because if they don't sell RAID5, they don't recover the R&D costs of
creating a RAID5 microkernel that has more lines of code than the Oracle7
executable. I'm not kidding.
