Abstract

Storage capacity demand is projected to grow exponentially in the coming decade and so will its contribution to the overall carbon footprint of computing devices. In recent years, cloud providers and device vendors have substantially reduced their carbon impact through improved power consumption and product distribution. However, by 2030, the manufacturing of flash-based storage devices will account for 1.7% of carbon emissions in the world. Therefore, reducing production-related carbon emissions of storage is key to sustainability in computing devices.

We present Sustainability-Oriented Storage (SOS), a new host-device co-design for personal storage devices, which opportunistically improves storage sustainability by: (1) targeting widely-produced flash-based personal storage devices; (2) reducing hardware production through optimizing bit density in existing materials, up to 50%; and (3) exploiting an underutilized gap between the effective lifespan of personal devices and longer lifespan of their underlying flash.

SOS automatically stores low-priority files, occupying most personal storage capacities, on high-density flash memories, currently designated for nearline storage. To avoid data loss, low-priority files are allowed to slightly degrade in quality over time. Switching to high-density memories, which maximize production material utilization, reduces the overall carbon footprint of personal storage devices.
