Ahh But Morris faster is not always better. 4200 or 5400 rpm is slower but creates less heat than say a 7200 rpm drive, the faster it goes the more heat is created. Older Books (and some newerbooks also) don't deal with heat all that well. Stick a 7200 rpm HD and a Processor upgrade (G3 etc..) and your looking at GLOD or worse... toasting something else. As for size 20, 30, 40 will work. IBM Travelstar are pretty good!
