Default Voices and DSP

I am currently using a protools HD system and would like to learn more about Voices and DSP.

I would like to understand in which cases you may put, for instance, 96 Voices with 6 DSPs instead of using 96 Voices with 3 DSPs.

3 chips vs. 6 chips:
6 chips will give you more buffer memory for getting files from the drive(s) (more of a problem w/ PATA drives than SATA drives)
3 chips has less buffer and more chips free for other things

Thank you for your fast answering.

Does that mean that, if using SATA, using 3 chips or 6 won't make any difference ?

depends on edit density and drive access/fragmentation levels

there was a post here recently, I will paraphrase it from memory - which may not be scientific, but the gist is there.
Older systems used to get PCI bottlenecks so had to split out the DSP more.
More modern drives and computers do not suffer from these limitations, so use the lower chip count per voice - unless you hit problems (which is unlikely).
More chips does not equal "sounds better" (more chips in my experience makes YOU fat - not your sound!)

cheers
