here's a post I made on the Apple message board regarding a test I did with a friend using his Powerbook G4 400 vs. my 550 using Live as the benchmark. This subject seems to come up alot so I thought people might like to see it.
--------------------------------------------------------------
"We did a test today, albeit unscientific, but still a test indeed. We each opened a new Live session and began to load the same 4 bar drum loop at 100bpm onto ordered tracks from 1 up. I got to 9 tracks and the Live CPU meter was at 51%. His was at 28%. We rounded up to an even 10 tracks and mine hit 55% and his it 30%. We then began to add a line effect called Grain Delay to each playing track. By the time I got to track 3 my level was touching 75% and his was at %41%. My interface became so slow I couldn't really do much else. I didn't experience any audio breakup or noise. Live makes audio playback priority over screen redraw so it stays solid. My friend was able to get a total of 23 tracks going all with the effect before his meter hit %75. We did the test again in OSX and the results were similar.
My machine: G4 Titanium 550 w/384 mb RAM
His machine: G4 Titanium 400 w/384 mb RAM
Neither of us had any other open apps or network connections at all. Needless to say I was astounded and I'm seriously considering trading DOWN for one of these old books. "

not sure either but...
i'm not sure what you mean by that...if you mean that one HD was more fragmented than the other, it wasn't. We each ran an "Index" of our HDs before the test. It's called "Indexing" on a Mac.
