Hi Richard ... I read an article that you posted about the IDE devices set
up , Which you said I believe you are using 6 IDE devices ? Can you explain
exactly the set up in how you have your 6 ? Thanks
 
If Richard doesn't get back you you, the answer is you may have 2 ide
devices on each channel. To have 6 devices you will need 3 channels.
Many motherboards had 2, some have 3 or 4. The IDE spec allows for 4
channels and so, up to 8 devices.
 
Hi ... I understand that but, Its how Richard has his IDE channel set up
that I am curious about , Here below is a post which he stated for someone
else who is using 3 ide channel , I'm more concern in the order which
Richard has his set up as ? If he would give details exactly how his is ?

Richard said :
I would set up the Maxtor 120 gig as primary master, the Plextor as primary
slave. Set the WD 300 as secondary "single" (WD does not allow you to have a
master without a slave attached - hence set as single drive).

The reasoning is as follows. If both drives are on the same IDE channel any
reads/writes to the drives are performed sequentially. The IDE channel
resources are "shared" between the two drives - they both can not be reading
or writing at the same time.

If each drive is attached to it's own IDE controller the drives can, and
will, read/write concurrently (at the same time). This will give you better
performance when working with large files. The operating system on the first
drive can be doing it's own thing as the second drive is reading or writing
large files, such as when ripping audio or rendering video.

You're confused. He is speaking about 3 IDE drives, not channels.

Hi!

I have primary and secondary IDE channels on the M/B. Each IDE channel will
support 2 drives. I currently have a 160 gig and a 120 gig drive connected
to the primary channel. I have a CD-DVD burner and CD-RW burner connected to
the secondary channel.

I also have a Promise ATA-100 controller card in a PCI slot. This card has 2
channels also. Each of the channels support 2 drives. I have another 160 gig
drive and a 40 gig drive on the primary channel of this card.

The main reason of my having drives on different controller channels is that
I have my pagefile set to use the 160 gig drive off of the Promise ATA-100
controller card. By doing this, the operating system/programs can read/write
"concurrently" with the pagefile, which is on another control channel. If
the pagefile were on either the same hard drive, or a second hard drive
connected to the same controller, where the operating system drive is
connected, the reading/writing would be consecutive, instead of concurrent.

I notice a definite (proved by my stopwatch) performance boost this way,
especially when rendering video files and working with Photoshop.

Hi .. Thanks for responsing back , Well from what I gather that would make
sense but , Correct me if I am wrong but , Did you suggest to Charley that
he/she should make there Maxtor 120gb HDD as his/her as primary master and
make him/her optical drive primary slave , Lastly make him/her other hard
drive as master on the secondary ?

Thanks
 
If Charley has only two IDE controllers, yes!

By placing the optical drive on the primary channel as a slave unit he is
free to place the 2nd hard drive on the secondary channel. He can thereby
place his pagefile on the 2nd drive where it will not interfere with the
operating system read/writes. Of course it is a two way street and the
pagefile can also write concurrently with anything that is reading/writing
to the main drive.

I don't know how I can make it any cleaner than that!

Another bennie is the swapfile isn't spotting throughout the windows
partition, causing other modified and new file writes to fragment.
Even though its just a tad slower, am using an ultrascsi hard drive for the
swapfile location rather than any hard drive on my Promise ATA100
controller. Have onboard ide too that's full up.
