Seagate Momentus 5400.2 120GB Hard Drive
November 03, 2005

Testing (continued):

Thermal Testing:

As mentioned, the thermal testing consisted of monitoring the idle and load temperatures of the hard drives' outer surfaces using a Cooler Master Aerogate bay device. The idle condition consisted of the system just sitting at the Windows desktop with no extra applications running. The load condition was created in one step by running SiSoft Sandra 2005's File System Benchmark for no less than one hour, and in a second step by playing a DiVX movie for another hour.


One probe from the Aerogate was affixed to the top of the drive (on the white data label) and a second probe was affixed to the edge of the drive. The higher reading was recorded, and in every case it turned out to be the temperature from the edge of the drives as monitored during the execution of the Sandra benchmark..


As you can see in the chart above, the Momentus drive idles at a slightly elevated temperature, but when stressed it is just barely warmer than the Toshiba drive spinning at 4200 RPM. Remembering that the system these drives were tested in is completely sealed with no cooling provided to the drives, the thermal performance is quite respectable. Considering the drives were able to operate at safe temperatures with no cooling only provides greater confidence for a long life when installed in a more conventional case.

Despite the higher rotating speed, the Momentus drive provided temperatures comparable to the 4200 RPM drive, and coupled with its performance characteristics makes it quite desirable for an application like this Mini-ITX HTPC.
