I saw the story on the front page about the 15000 rpm seagate drives.  I guess my biggest issue with the ramped up rpms is heat.  I think drives got significantly hotter when going from 5000 rpms to 7500 rpms.  I still wish 5000rpm drives were more readily available as they make great expansion drives for TiVos and the like…  With 15000rpms I have to assume they will be that much hotter.  Am I mistaken in my assumption or is there something to it?
