Extrnal Drive Optimization For G4 800, HOW DO I GET THE BEST PERFORMANCE ? Options

[COLD]

HELLO GUYS,
I hvae a G4/800/ 80 Gig w/ 17in. flat screen ,Fire Wire 400.
I recently bought a160G Mercury(OWC) hard drive and would like to know how to get the best performance from it.

1.Do I keep my audio software on the internal drive and save to the external drive?
2. Is there some optimization software to use so that my disks won't get fragmented?

I am using DP4.5 also recently aquired.
Any suggestiosn please?

OS X as a good unix BSD under the hood defrags automatically files under 30 MB. The file system is also way more efficient to handle fragmented files.

So the main question is what to do with BIG files: either you use a dedicated software (with the usual dangers it can have) techtools/diskwarrior for example. Or you use another drive, copy the files on the 2nd drive, erase the first one and copy back the files.

But you can't do that with the system drive! (copy the system erase copy back, it won't do at all) you need to clone it etc. which is a very different business.
