About half the power consumption of HDD, SSD may save the earth

Recording medium using flash memory instead of hard disk "SSD (solid, steady drive)"Is becoming widespread, but it became clear that low power consumption may contribute to energy saving on a global scale.

Details are as follows.
ISuppli: SSD Energy Savings Could Power A Nation - HotHardware

According to this article, the survey company iSuppli has investigated the power consumption when introducing the SSD to the company's data center.

This is how much power consumption will be reduced if you replace the Serial-Attached SCSI (SAS) interface connection type HDD of 15,000 revolutions per minute currently being used in the data center with SSD.

The power consumption of HDD is about 14 watts per one, whereas the power consumption per SSD is about 7 watts, which is half of that. If you convert HDDs to SSDs on a global scale, the total accumulated 166,443 MWh (166.66 millionKWhWe are reporting that it will be possible to reduce the power consumption of our products.

This is a graph of power consumption that can be reduced by converting to SSD. It is increasing year by year.


By the way, Tokyo Electric Power Company announced by Tokyo Electric Power Company on January 19th 2008, Gunma, Tochigi, Ibaraki, Saitama, Chiba, Kanagawa, Yamanashi and Shizuoka prefectures of the east of FujiWhen the total demand electricity amount is 107,180 MW (1,070.331 million kWh), It seems that the energy saving effect obtained by converting to SSD is an outright scale.
