IDE array question

T

The Seabat

This has probably been debated forever, but maybe some one can give me
a difinitive answer. Ha!

I have two 40GB hard drives, one DVD burner and one CD/RW burner. What
is the best way to arrainge these puppies on the two IDE channels for
optimum performance? I don't plan on ever doing any disc-to-disc
copying, so that is not a concern. Right now I have the boot drive and
the DVD burner on the Primary channel and the other hard drive and the
CD/RW burner on the Secondary channel. Both the CD and DVD drives are
set as slaves and the hard drives set as masters.

Someone said that it is better to have both hard drives on the Primary
and the two burners on the Secondary. Is this better than the way I
have it?

It's better to divide drives of a given type across multiple
channels. Your existing configuration is optimal, except you
should swap your DVD and CDRW, i.e. put your DVD
burner as slave on the secondary channel instead of the
primary. A DVD burner has to move a lot more data than a
CDRW drive, and will be far more easily starved if you're
doing lots of multitasking while burning discs.

I had a wierd experience regarding this recently. A 2.4GHz Pentium 4 PC
using an Asus P4PE motherboard. I had a Pioneer 109 DVD burner sitting by
itself on one IDE cable, and my two hard drives sharing another IDE cable.
With this combination, I noticed that even though I set my DVD burner to
burn at 8x speed, the total burning time was equivalent to 2x. I also
noticed that the LED on the DVD burner flashed slowly on and off, and I
thought this was normal to mean that the DVD was in operation. (I found
out later that, no, if the DVD was being constantly supplied with new data
and not being starved, then the LED would be on constantly during the
write operation. So apparently I was not getting data fast enough to the
DVD burner here). I also had many DVD write failures when burning from
images located on the "slave" hard drive.

My hard drive started to become quite noisy, and anticipating a pending
failure, I replaced it with a new IDE hard drive, same basic type but only
larger (80GB instead of 40GB). While doing so I re-installed Windows 2000.
Since I had more hard disk space, I only installed the one hard drive. Now
the boot hard drive is on one IDE cable, the DVD burner on the other.

And now when I burn a DVD at 8x, it really does it in the time it should
take for 8x writing, and the DVD LED is on all the time.

So for my system, for some wierd reason, having two hard drives on one IDE
cable and with my optical storage (DVD burner) on the other did not work
out well at all! The only other possible explanation is that my old
Windows operating system was at fault, after so many years of operation.

Anyone have an idea why this happened, regarding the extremely slow data
transfer rate?

No such animal.

It makes most sense to have both optical drives on one
ribbon cable and the hard drives on the other, just because
thats all that works with the legal cables in most cases.

Bet you wouldnt be able to pick between that config
and the other one in a proper double blind trial.
Both the CD and DVD drives are set as slaves

Slavery has been illegal for over a century or more now.

And that sort of thing for quite a few decades now too.

They're right.

Yes.

It's not strange at all. IDE doesn't efficiently handle multiple
devices on one channel. In other protocols such as SCSI,
when one device has work to do, it can disconnect from the
bus and allow another device on that same channel to work
concurrently. IDE has no similar feature, so when one
device has work to do, the other device on that same
channel simply has to wait its turn. Very inefficient.

I wouldn't change a thing... But you're right; this could be a long
thread!

Seabat:
As you have or will have discovered, you're going to get a number of
responses
recommending this or that configuration of your IDE-connected devices. Based
upon my own experience and tests the computer facility I was associated with
conducted a few years ago on this very issue -- in virtually every case,
aside from
connecting one's working HD as Primary Master, it really didn't matter
performance-wise how the remaining drives (hard drives & optical drives)
were connected on the two IDE channels. I should add that (as I recall) all
of our tests in this area involved the XP OS, but I don't think there would
have been any significant differences using the Win9x/Me operating systems.
Nearly all of our tests were conducted with connecting two hard drives and
two optical drives - a CD-ROM & a CD-DVD burner.

Note I said "virtually every case". There were some rather rare situations
where it did matter with respect to HD connections/configurations. This
usually involved the encoding/decoding of extremely large video files
(gigabytes in size).

Also, again in some very rare instances, where the process involved copying
CDs (we didn't use DVDs) from one optical drive to another optical drive,
there were some instances (rare as they might be) where the configuration of
the optical drives *did* matter in terms of performance. Strangely enough,
in that situation we were unable to come up with a hard & fast rule as to
the best configuration of the optical drives. In some cases we found better,
i.e., faster, data transfer rates when both optical drives were connected on
the same channel. In other cases it was best to connect each on a separate
IDE channel. And we could find no correlation involving the make/model of
these optical drives. It was quite puzzling. But let me emphasize that these
were relatively rare exceptions. As I previously stated, we generally found
*no* significant performance differences regardless of how the optical
drives were connected/configured.

But do this. Experiment for yourself. In this instance don't rely on my
advice or anyone else's. Try different configurations of your devices and
run speed tests based on your normal day-to-day activities with the
computer, i.e., accessing programs, moving/copying files, burning CDs, etc.
See if there's any performance difference depending upon how this or that
device is connected and thus determine the best setup for your particular
needs.

For the fastest speeds of data transfer in your systemyou want to have the
two harddrives on IDE 1 and the two optical drives on IDE 2. The optical
drives are much slower in transfer rates than the harddrives and so you do
NOT want to mix them on an IDE channel.

Utterly mangled. The hard drives dont run at the speed
of the optical drives if they are on the same IDE channel.

Another question in the same vein who should be the master drive the
one with the os on it or the other?

Its traditional to put the OS on the master
but most modern bios will boot the slave too.
