heh... thank goodness for _software_ raid, hm?
aren't Quantum drives put out by Maxtor? and isn't the Quantum line killed? if
my memory is serving me right on this, what you are seeing is the difference
between a middle of the road hard disk manufacturer whose speciality is not
really high end drives (maxtor) versus a top flight disk manu who caters to
the enterprise (IBM).

yeah, dieing drives are generally pretty neat.

which is, of course, why everyone who sets up serious data systems uses SCSI
if they are going with a commodity solution? right. maybe you should start
calling data centre around the world and letting them know. ;-)
seriously though, SCSI is generally better than IDE. the gap has narrowed
CONSIDERABLY over the years, however. primarilly because of the HUGE market
for IDE drives, ergo the increased R&D budgets. you can primarily thank a
certain company in Redmond and another associated with the colour blue for
that. had the same efforts been put into SCSI, not only would the prices be
what they are for IDE, we'd probably have larger, faster and more reliable
drives today. SCSI technology has not topped out, is more scalable and had a
head start on IDE.
