Should disc go on Primary or Secondard Channel

I have pentium II 128 Mb, c drive = 20Gb, d drive 6 GB, E = CD. F= zip. Both hard drives are EIDE.

The c drive is a Maxtor 92048U8, a 20 GB 33 Mbytes/sec, UDMA-Mode 2 and
 the d drive is a Western Digital 36400 6.448 GB UDMA 33 Mbytes/sec

Should I put both hds on primary channel or one on each.  I have heard that the channel runs at the speed of the slowest connection, is that true?  What combination will give the fastest hd access?

Thanks

I have been told that HD as Masters on pri and sec will work the best. I have two drives on my primary.I have tried switching them to masters on each IDE controller and saw no differents. The access to my main drive(with the os)work the same. My secondary made no diff either.
I'm sure some will have diff opinions but I personnally did notice a thing. I would say the way you have you box configured is fine.

Is the 20GB DMA33 or DMA66? it should be at least DMA33
What about the 6GB?
If you put a DMA33 or DMA66 on the same cable as a non DMA HD then you will slow it down. Without knowing what your MB is, then about all I can give is general info.

If it was mine I would set each HD on its own IDE.
Also make sure you have DMA enabled too, this will help speed things up.

IMHO, it all depends on the CD-ROM drive. If you have an IDE CD-ROM, it will probably slow down the other drive on the same channel. Therefore, if that is the case, you're probably better off using your two hard drives on the primary channel.

If your CD-ROM does not reside on the secondary channel, however, I suggest you put each hard drive on its own channel.

I like bbousquet's answer, but since I have four drives, (two hds, a 250 mb zip and a cd-rom) I wonder if having the cd on one and the cd on the other channel won't slow both channel down.

My experience so far has been the same as Sogie, but I haven't been able to compare (no real measurement tools) having just having one hard drive per channel vs the set up where a hard drive and a zip of cd are also on the channel.

If my assumption that bbusquet's answer also applies to having the zip on one channel and the zip on the second channel, then I will award the points to him. Everyone has been very helpful and deserves some points, too bad I can't allocate.

Thanks

I had forgotten to take that ZIP drive into account (I used to have a parallel port version so I didn't think it was IDE).

Therefore, to summarize it all:

You have 2 IDE hard drives
You have 1 IDE CD-ROM
You have 1 IDE ZIP drive

Considering the fact that your two 'slow' IDE devices are the CD-ROM and the ZIP drive, you don't seem to have much choices as far as layout goes. I would, personnally, keep the two HD's together and leave the CD-ROM and ZIP on the 2nd controller.

I haven't fooled around with that alot, but some sound cards have an on-board IDE controller which can be used as a tertiary IDE channel. But I don't think it could really help you as you have two 'slow' devices, not only one.

I hope this helps (sometimes I can't forgive myself for not buying an all-SCSI setup...) ;-)
