R: Questions

[David Brower]

Long term, the cost advantages of IDE drives may become
truly compelling.  They are currently 1/2 the price of
SCSI drives, and that trend shows no signs of changing.
Thus, it is the case that for the same price, today you can
get N bits on a SCSI drive, or N*2 bits of IDE, mirrored
through s/w and the nbd.  This kind of configuration ought
to challenge some of our assumptions!
