IDE has one real drawback, you can't chain anywhere near the same extent,
so you really have to replace one drive with a larger drive for upgrades.

Don't get me wrong, for a high-end machine, I'd go SCSI all the way.

But for a machine where you do not head real fast disk access, and
can live with a reasonable max of 2-3 Gig, SCSI can't compare to IDE for
a cheap fast solution.

And on older (486) machines, a VLB IDE controller still gives better
performance (by observation, regardless of whether its technically possible).
