Power and heat consumption

Quite rightly, there is growing concern for the environment and the side-effects of energy consumption. As a consequence, consumers and maufacturers are demanding greener, less power-hungry products. Which is why Hitachi GST has developed a range of hard drive models which manage to use less power but still don't compromise performance.

Low power idle
To save energy, many of our drives are designed to switch to a low wattage idle power mode if recording or playback pauses for longer periods. Because of this, they require smaller power supplies and less cooling, which as well as being friendlier to the planet, may help extend the life of the hard drive and the host product.

Thermal monitoring
The core temperature of the hard disk drive can be monitored intelligently. If a fan or air-conditioning has failed, the system will raise the alarm and the fault can be fixed. The system can also alternatively control the device fan to speed up (to make the disk cooler) or slow down (to make the device quieter). The Smart Command Transport feature set includes the ability to log the temperature at regular intervals – this can be reported to the system, or could be used in field returns to see the history of the drive temperature for failure analysis.

HiVERT™
Hitachi Voltage Efficiency Regulator (HiVERT) a technology developed by Hitachi GST brings unprecedented levels of power efficiency for 2.5-inch (and some 3.5-inch) hard disk drives – which is not only practical but eco-friendly too.
