I searched around and got a few ideas, but not really enough info to make a decision. So - for all of you with your nearly obsolete Powerbook G4's I'm looking for your recommendations! I have a few bucks and am looking to do one last upgrade to my 15" Aluminum Powerbook G4. Basically this will take it through until its death, whenever down the road that may be. I will max out the ram and replace the hard drive. My question: What is the best, quietest, fastest, coolest running hard drive I could get? I'll be looking for something in the 100GB range, probably, I don't really need the internal drive to be much bigger, I have other external drives for data capacity purposes.
