True in most cases. Over the years I have seen prices very close on many
SCSI and IDE drives with similar capacity. IDE is slower. However, there
is a real advantage to having a SCSI intelligent controller and the
number of drives you can have. I would have run out IDE drives a long
time ago, or would have to spend a lot of money on an expensive IDE
controller for more than 4 drives.

Actually, for a long time after they came out you could only get them as
LPT or SCSI. There were no IDE ZIP drives for a long time. I never have
had any experience with LPT ZIP drives, but the Ditto LPT tape drives
seem to work just fine with DOS and NT. I just recently got one of
these, so I have not had a lot of experience with it yet. I don't have a
printer connected either at this time but did see some notes about using
it with certain printers.

Most people do not have a problem, but I have seen many problems with
them. Sometimes, for example, a person has gotten a second drive and
wanted to use it as the master and may not be able to if it was a
different brand. In the past if you connected a slow drive with a faster
drive, then the maximum transfer rate for both drives would the slower
rate. I don't know if this has ever been fixed and if it has, at what
point it was fixed.
Basically all the so-called IDE controller is, is a buffer between the
drive and the motherboard bus. All the electronics is in the drive
itself. There have been something like six different standards for IDE
and they do not seem to be 100% backward compatible.

There is quite a bit more to it. EIDE has busmastering capability, which
IDE does not. I don't believe that IDE drives could do block transfers.

Yes and CD-R/W.

Until recently with some of the newer drives, the write speed has been
slow. I am not talking about five years ago. I was thinking of buying a
R/W drive about a years ago, then saw the DVD RAM drives and compared
speeds. Since the DVDs were as fast for write speed, I decided to wait
and buy a DVD RAM drive when the prices drop and the bugs have been
worked out and it will be a SCSI drive. (I don't think they even have
those in IDE yet.)

This is a very recent drive. My main point is why should some have to
upgrade everything when something new comes along. I do not have to do
this with SCSI. I can mix the old technology stuff with the newer stuff.

You did not read what I wrote very well. I said a K6-III+ 450Mhz. If you
wish to do some research on it, you'll find that it is comparable in
speed to the Duron! The reason I chose this, is because I don't want to
invest in a new ATX case and power supply. I also get 4 ISA slots if I
need them. My 56K modem is ISA as is my Ethernet card and my Central
Point Deluxe Option board.
