In today’s rapidly evolving technology landscape, e-waste and embodied carbon remain significant concerns. With the growth of the Internet of Things and the precipitous demand for all things artificial intelligence (AI), data storage requirements are expected to surge — amplifying safety and efficiency challenges around device management.

The Circular Drive Initiative (CDI) embraces circularity principles to curb e-waste in data storage hardware. It draws inspiration from strategies that aim to minimize waste by maximizing the lifespan of products and materials. Specifically, it advocates for sustainable hardware mechanisms using system-based approaches that take into account the entire product lifecycle.

As data storage enters a new phase, CDI is uniting storage industry leaders in a push to minimize environmental impact, tackle resource security issues, and promote secure reuse. By encouraging companies to adopt long-term strategies, CDI is at the forefront of the drive towards sustainable data storage.

The Story

The Circular Drive Initiative operates as a consortium uniting global leaders in digital storage, data centers, sustainability, and blockchain. The CDI’s core mission revolves around fostering sustainability in storage practices, combating e-waste by championing, enabling, and advocating for the secure reuse of storage hardware.

CDI was convened in November 2022 under the leadership of William McDonough, an architect renowned for his work on circular design and the development of the “cradle-to-cradle” principle. The consortium brings together a dream team of industry leaders to formulate and implement sustainability strategies. Members include prominent drive manufacturers like Seagate, memory leaders such as Micron, and eco-friendly blockchain groups like the Chia Network.

As an inclusive coalition, the Circular Drive Initiative welcomes storage vendors, hyperscale data centers, original equipment manufacturers, IT asset disposition companies, and anyone else passionate about making a meaningful impact in sustainable data storage.

“CDI is the only place where drive manufacturers, hyperscalers, OEMs, and ITADs can get together to really tackle the barriers to circularity, including storage security and media sanitization education,” remarked CDI representative and storage industry leader Jonmichael Hands.

CDI is on a mission to bring together experts passionate about taking sustainable storage to the next level.

The Strategies

Eliminating e-waste is a multifaceted goal. Thankfully, companies can tackle it by using several circularity practices in tandem. In addition to promoting industry education around sustainability issues, key practices include:

The circular economy model prioritizes efficiency by prolonging the utilization of resources and minimizing waste. Its scope extends far beyond mere recycling. While recycling is ultimately a necessary step in the circularity process, a 2020 study showed that extending the life of a device — rather than disposing of it prematurely — can result in a 275x difference in overall carbon impact. A truly circular economy entails the comprehensive tracking of drives throughout their lifespan to facilitate extended usage in tandem with responsible recycling.

Recycling is ultimately essential, but much more is needed. Together with reuse, circular design, and lifecycle management, CDI is furthering the vision of a cradle-to-cradle storage ecosystem.

Smooth collaboration is key to implementing these initiatives, and CDI benefits from a robust network. In addition to manufacturers, its members comprise leading ITAD companies and distributors, including Horizon Technology.

CDI’s mission is to promote the reuse of drives by educating end users and creating de facto test and data sanitization standards. This helps remove any questions and concerns around the reuse of drives.

The Outreach

In an age of generative AI, massive data sets are worth their weight in gold. However, this also highlights the critical role of storing data not just sustainably, but securely. The more data you store, the greater the chance that sensitive data is leaked when a drive is improperly disposed of. The problem is that misunderstanding what security requires leads to unsustainable practices. As CDI puts it, the current state of play for the industry is “we shred everything.”

As is so often the case in industry, clear communication is half the battle. Effectively addressing such sensitive issues as safety and privacy necessitates the distribution of credible, decisive information.

To this end, the CDI published a white paper together with the Open Compute Project (OCP). Entitled “Data Sanitization for the Circular Economy,” the report highlights the use of ‘purge media sanitization.’ Purge involves rendering data recovery infeasible through laboratory techniques while maintaining the drive in a reusable state.

Promoting awareness of purge sanitization is paramount, since concerns about data security often become barriers to achieving circularity. Currently, data centers destroy up to 90% of storage devices after first use due to these security concerns. According to the white paper’s executive summary, “this eliminates the possibility of a circular economy because it prevents any further uses of the devices”.

As a remedy, the white paper focuses on the new IEEE 2883 standards. “Media sanitization is a well-researched and understood field”, the report authors argue. New standards reflect state-of-the-art ITAD techniques, and make it clear that best practice is not necessarily shredding.

When it comes to encouraging reuse, communication is half the battle. CDI is educating industries about new standards committed to achieving data security in used drives without resorting to outright destruction.

In a separate large-scale study of almost 118,000 drives published in the European Journal of Electrical Engineering and Computer Science, as many as 87% of the drives tested remained fit for reuse following secure sanitization in accordance with the IEEE 2883-2022 standards.

Innovation in Sustainable Data Storage

The CDI’s agenda is clear: extend first use, encourage purging over destruction, and enable resale. With the release of the IEEE 2883 standard, there’s good reason to hope that the message of reuse will more easily reach the ears of organizations and thought leaders.

This will be achieved by bringing together the best and brightest minds in the industry to address implementation challenges and communicate solutions. After all, when it comes to circularity, reuse significantly mitigates carbon impact and extends value recovery.

“Currently CDI is working on comprehensive guidelines for media sanitization, heavily leveraging and prioritizing the IEEE 2883-2022 specification and work,” Hands explained. “We are also working on open-source software for health grading to enable more transparency and understanding of device health and reliability in the secondhand market.”

CDI membership is also growing, with the consortium expecting to add more big names to its roster.

Making data center storage more sustainable will require innovation, organization, and above all collaboration.

Additionally, new technical advancements will play a critical role in shaping sustainability infrastructure and practices in the future. Technologies like self-regenerating drives, for example, will create new opportunities for extending hardware life cycles.

NVMe is an ever-growing slice of enterprise SSD storage. OCP’s Datacenter NVME SSD Specification includes a section which lets you interpret SMART identifier information. This allows you to effectively monitor the health of your NVMe devices.

The development and use of HAMR (Heat-Assisted Magnetic Recording) drives are another solution with the potential to revolutionize the HDD industry. This technology uses a laser to heat a tiny spot on the disk, allowing data to be written in smaller and more densely packed bits. “A 20 TB drive and 32 TB HAMR drive share the same carbon footprint, both in embedded emissions from manufacturing and power consumed in its lifetime,” according to Seagate, a pioneer in HAMR development.

However, caution is in order. When it comes to destruction, increased areal density means that shredding is now more risky, since tiny fragments of drive can still hold a lot of data. Melting and incineration work, but take more power. Hopefully, this will help push companies towards secure purge methods, as they pursue power savings while maintaining security.

The Future of Sustainable Data Storage

The Circular Drive Initiative champions circular economy principles to combat e-waste, minimize environmental impact, and drive sustainable growth in sustainable data storage. By uniting global leaders and advocating for secure reuse, CDI addresses pressing concerns of e-waste and carbon emissions in the technology landscape. Its comprehensive strategy — encompassing standards development, circular business models, industry education, and responsible recycling — seeks impactful change.

Through clear communication and partnerships like with the Open Compute Project, CDI emphasizes ‘purge media sanitization’ as a means to securely erase data, enabling secondary use. Looking forward, CDI remains committed to extending first use, promoting purging over destruction, and facilitating industry-wide adoption. Technological advancements, including self-regenerating drives and HAMR technology, hold promise for more sustainable, more efficient storage solutions.

As demand for data storage accelerates, shaping a sustainable future for storage technology through collaboration, innovation, and knowledge sharing has never been more timely or pressing.
