>  Why is it that there are no RAID 5 controlers for IDE?

My gut reaction was to say:

	"The same reason there are no after-market turbo
	 chargers for those little gas scooters that seem
	 to be so popular lately."

...as a backhand reference to the fact that IDE dtill does not
support concurrent outstanding I/O via tagged command queueing.

But the fact is that there are IDE RAID controllers, even though
I personally think that a server will have much more need of
concurrency than a desktop.
