The majority of cloud data is and will be stored on hard disk drives, simply because these drives offer the most economic cost per capacity for investment in large online storages. However, with the exponential growth of cloud data, the power consumption of these online storages is becoming a strong concern. New technologies and architecture are urgently needed to limit the power consumption of stored cloud data—in a period of rapid growth. In his CloudFest 2022 keynote, Rainer Kaese, Senior Manager at Toshiba, presented a set of technologies and approaches to reduce the power consumption of the single hard disk drive, as well as further reduction potential related to how hard disk drives are operated in cloud data centers.
