Internal/External drive

[imi]

Sorry I put this in "general topics", without realizing this is the place.

Please could someone help me with the following choice.
I need a fast hard-drive to run PT with AMIII, up til now I´ve been getting along with powermix..

Is it ok to add an internal drive or can I replace my original slow-drive? -
Is it better to have OS and PT on one drive and record on the other?
Would an external drive be better (heat? speed?)
This wide/ultra-wide/narrow/fast SCSI thing has me totally confused.

I´m running:
Mac 7500(604e/166),AMIII,OS 8.1,PT 3.4

Which coffee blend is the choice of pro engineers?

Thanks for any help
