By Namrata Sengupta, CDI member representative from BitRaser Enterprise data is growing at a phenomenal rate that requires going above and beyond the limits of traditional storage architecture, demanding more scalability, performance, and a cost-effective storage solution. This surge has further led to the adoption of high-density, lower-cost technology-based drives such as Shingled Magnetic Recording (SMR), which delivers significantly greater areal density than traditional CMR (Conventional Magnetic Recording) drives. SMR drive is a storage technology that increases the areal density of hard drives, allowing more data to be stored per square inch of the platter. This higher density is achieved by altering how tracks are written on the disk. Unlike traditional CMR drives, where tracks sit side by side with clear separation and can be rewritten independently, SMR writes each track so that it partially overlaps the one before it, much like shingles on a roof (See Image 1).   Image 1: SMR Drive Track Organization (Source: bitraser.com)   In short, SMR drives use ‘overlapping recording tracks,’ a design that boosts capacity but forces them to use sequential writes and Read-Modify-Write operations.  The design, therefore: Narrows the width of the write track Allows subsequent tracks to overlap and Packs more [...]

Authors: Smith & Associates Smith recently interviewed representatives from large hyperscalers, OEMs, and other key players in the electronics industry under the Circular Drive Initiative (CDI) and Open Compute Project (OCP) umbrella. Through these interviews, we gained a deeper understanding of carbon avoidance and carbon accounting as it pertains to companies that utilize electronic devices in their workflow processes and the changes that should be made for a more sustainable industry. The interviews highlighted key topics, including discussions on amortization, reuse, and insets as areas of concern and consideration. Amortization and Carbon Responsibility Amortization is a specific method derived from accounting that enables an organization to spread costs—typically of longer-term assets—over a period of time. For the purposes of our industry’s needs, amortization will be applied when discussing the longevity of an electronic device and its embodied carbon from the first user to the second user and to any subsequent users thereafter. During the interviews, a central question was raised: Who is responsible for embodied carbon? Coming to a unanimous decision on carbon reporting standards is a multifaceted goal that would require the marriage of reporting standards, best practices, and clear accountability of carbon emissions. Currently, the accounting methods [...]

As global demand for data storage reaches unprecedented levels, manufacturers are struggling to keep pace. But the environmental cost of continuously producing new hardware is unsustainable. That’s where circular practices—like refurbishment and reuse—come into play, offering a powerful solution to both meet demand and reduce environmental impact.Research published in the European Journal of Electrical Engineering and Computer Science (EJECE 2024) explores this issue, focusing on the circularity gap in IT hardware. The findings, led by Interact, Cedar, and the Circular Drive Initiative (CDI), are eye-opening. The Circular Economy Potential A year-long study involving over 117,000 storage devices—both HDDs and SSDs—was conducted to assess how many drives could be securely erased and refurbished for reuse. The results revealed that 87% of these drives were suitable for a second life after successful data sanitization. The Untapped Opportunity In 2020, a staggering 628 million SSDs and HDDs were manufactured, many of which are reaching the end of their first life in 2024. While about 62 to 64 million of these drives will be reused, over 480 million drives that are perfectly viable for reuse will likely be destroyed or disposed of instead. This represents an enormous missed opportunity, both environmentally and economically. Key [...]

Author: Jonmichael Hands, Circular Drive Initiative In the dynamic world of data security, standards for media sanitization play a critical role in safeguarding sensitive information from unauthorized recovery. The recent release of the IEEE 2883-2022 standard provides a fresh perspective on media sanitization, tailored to keep pace with modern storage technologies. This article compares the established NIST SP 800-88r1 and the newly minted IEEE 2883-2022, highlighting their global reach, support for contemporary devices, documentation, and compliance criteria.  Global Reach IEEE is an international body, and its standards are widely accepted and used globally. NIST is a Government Authority and non-regulatory federal agency within the U.S. Department of Commerce. NIST standards do often have implications for policy and regulatory compliance Support for modern devices NIST SP 800-88r1 was written in 2014 and published in 2015. The first NVMe SSDs were released in 2014, but NVMe is now the most popular storage interface for SSDs, making up hundreds of millions of devices per year. IEEE 2883-2022 was published in June 2022 and includes the latest media sanitization requirements from modern versions of storage interfaces. IEEE 2883-2022 contains the exact storage interface commands that define a clear and a purge by interface (NVM, SATA, [...]

Summary Chia co-authored a new whitepaper on the impact of data sanitization on the circular economy, suggesting a practical solution to data security and storage reuse. Read the whitepaper here. Background Shortly after the Chia mainnet launch, hard drives worldwide were sold out, prices increased, and lead times increased. Because of the dramatic increase in demand, a few IT asset disposition (ITAD) providers wanted to know more about Chia and how drives are used for farming. When meeting with these ITADs, we learned the actual scale of how many drives were shredded per year for their customers. We pleaded to free these drives up for Chia farming, but it wasn’t up to them – it was up to their customers. In the hyperscale and enterprise space, any leak of customer data is catastrophic. The idea for Circular Drive Initiative was born – to activate collaborative work between hyperscalers, drive vendors, and ITADs, dedicated to driving secure storage reuse. Chia joined OCP to start discussing sustainability with the industry leaders in technology. The CDI workgroup decided sanitization and reuse was the first and most important topic to tackle. Addressing the issue, not the symptoms I discovered through my storage network that a new specification on media sanitization [...]
