Would a WD Scorpio Black 7200 RPM HDD or Caviar Black (i like the 5y warranty from WD) overheat the system. Would the temperature difference between a 5400 and a 7200 rpm be a problem? My PS3 stays on for hours at a time for downloads, movies, shows, games, and music. It sits well ventilated. I would get an SSD for my PS3 but there's no TRIM Support, RAId, or Garbage Collection on a PS3 for SSD and i don't want the drive to slow down over time. (32•F Freezing Temperature, 33•F Water wont freeze.)
