Hybrid, IDE internal , SCSI External
One thing I can do with my SCSI Castlewood ORB drive that I couldn't do
with the IDE one is: disconnect it from my home machine, pop it in
the briefcase, drive to work, hook it up to the work machine, and start
accessing the data I saved there. (Note I do not power off either machine;
if I suspect that it might cause conflicts I go into device manager and
do a refresh on the installed devices). That's hot plugability in action.
IDE has advantages in price, and acceptable performance for most users.
With the newer ATA standards, it meets the average requirements of the majority
of users. But there is really no need (or excuse) to bash SCSI over it,
as SCSI still offers functionality, adaptability, and performance
characteristics that even the latest IDE standard was never designed to apply.
There are times when speed and flexibility are more critical than capacity,
and those are the areas where SCSI still shines. Yes, it is more expensive,
but those drives are also (arguably) built to higher specs than their 7200
and 5400 RPM cousins. Consider that there have already been posters to
this (and other) forums saying they would pay a little extra premium for
the possiblility of 10000RPM IDE drives.
SerialATA is no more "right around the corner" than any other currently
hyped next generation technology. By that same whitepaper it will be
halfway thru 2002 before we see any large volume of devices supporting it.
And even then, the drives running on it will barely be able to reach the
level of ATA66 speed. Also, I don't see anything on that white paper that
addresses the growing desire for IDE RAID solutions.
