Temperature And Power Consumption
No surprises here: the energy-saving mechanisms and the lower spindle speeds of the Hitachi Deskstar 5K3000 and the Western Digital Caviar Green WD30EZRS show their impact on operating temperatures, which are much higher on the performance drives.
The green drives also dominate in terms of power consumption.
It is obvious that the Hitachi Deskstar 5K3000 and the Western Digital Caviar Green WD30EZRS are the performance per watt champions.
