I want to replace the 80gb 4200rpm hard drive in my 15" 1.5GHz Powerbook. My question is this, should I get the new 100gb 5400rpm HD or the 60gb 7200rpm HD? I don't really need the size of the 100gb but I'm concerned if the 7200rpm HD will put out too much heat and decrease battery power significantly over the 5400rpm version.
If anyone has put a 7200rpm HD in their Powerbook please let me know how it is.
