The Seagate ST31000358AS hdd is cooler on my test set-up with temperature going up to +10 C above ambient, while the Western Digital Green WD10EARS-00Y5B1 hdd going up top +13 C over the ambient temperature.
The Seagate drive is significantly faster than the WD Green drive of the same capacity. The Seagate drive though is faster, but is noisy – when the spindle spins the noise can be annoying at time. WD Green is whisper quiet and consumes less power. The WD Green hdd is slightly warmer in operation compared to the Seagate 7200.12.
My recommendation is the WD Green HDD WD10EARS-00Y5B1, the speed is adequate for a average desktop, low power and silent. If you are looking for performance use this WD Green WD10EARS-00Y5B1 with a SSD as a boot disk.
