For hyperscalers operating global infrastructure, secure data destruction is as operationally critical as deploying compute capacity itself. As these organizations expand across vast campuses, multiple jurisdictions, and complex supply chains, they must securely retire and destroy millions of drives under tightly controlled, auditable conditions.

However, the challenge extends beyond physical destruction. Modern hyperscale campuses can span multiple buildings in remote locations, housing thousands of servers and hundreds of thousands of drives. Maintaining continuous visibility over those assets – while preserving security, chain of custody, and accurate lifecycle tracking – becomes an immense operational undertaking.

One of the defining challenges is maintaining consistent destruction standards across global operations. Every retired drive – regardless of the regulatory environment, staffing model, or infrastructure constraints – must be subject to the same verifiable process, because at global scale, inconsistency becomes a security vulnerability in its own right.

For organizations building globally repeatable decommissioning programs, consistency is every bit as important as throughput. A process that works in a flagship campus but cannot be reliably replicated across regions quickly becomes operationally fragile, creating gaps in oversight and increasing risk exposure. As Fran Nutter, engineering manager at SEM, explains:

“If you had to, you could prove to customers, investors, media, or anyone else involved that you’ve tracked that drive and its data throughout its entire life – knowing exactly where it is at any moment, and proving it has in fact been destroyed.”

That level of traceability is essential because all data must be treated as mission-critical. Should sensitive information fall into the wrong hands, the consequences can be severe, both for the organization itself and for the customers who entrust it with their data.

The risks of failure are well-documented. One of the most widely cited examples is the Morgan Stanley data breach, which stemmed from shortcomings in third-party data destruction through an IT Asset Disposition (ITAD) vendor. Drives that should have been definitively destroyed were instead repurposed and resold without adequate sanitization, demonstrating how weaknesses in end-of-life processes can expose organizations to significant financial, regulatory, and reputational damage.

In a hyperscale environment where millions of assets are retired over time, a robust data decommissioning program is a critical safeguard against systemic risk.

What separates a mature decommissioning program from simply destroying drives?

Aside from determining how data is destroyed, a successful data decommissioning program defines how control is maintained from the moment an asset leaves its manufacturing site, while it’s in service, and ultimately that its destruction can be proven beyond doubt.

Organizations are handling highly sensitive, mission-critical information – data without which essential services simply cannot be delivered. Protecting that information demands a comprehensive framework encompassing serialized asset tracking, secure data sanitization, chain of custody controls, internal transport procedures, environmental compliance, and trained personnel – all operating within live 24/7 production environments.

At hyperscale, the operational dimension is equally important. A cost-effective decommissioning program maximizes equipment uptime, has been thoroughly pilot-tested for reliability, and maintains sufficient space capacity to support around-the-clock operations without interruption.

Chain of custody

At the center of any mature decommissioning program sits a chain of custody. It provides demonstrable proof that storage media has been controlled, protected, and properly sanitized throughout its lifecycle, creating the traceability required not only for regulatory compliance and legal defensibility, but for maintaining customer trust.

That control begins with data categorization, ensuring information is classified by sensitivity so that the appropriate sanitization method can be applied.

End-of-life policies

From there, organizations establish clear standards for cryptographic erasure, degaussing, and physical destruction, supported by verification and auditing processes that generate a Certificate of Destruction for every retired asset.

Compliance with frameworks such as NIST 800-88, GDPR, and HIPAA must be embedded throughout, ensuring hardware remains secure from the moment it leaves service until it is destroyed, recycled, or refurbished.

“It’s an abundance of caution, and it’s emotional. Everyone has to feel highly confident that information is secure – that it hasn’t just been overwritten or had access keys destroyed. The chain of custody has to be visible now and in the future, as data recovery methods inevitably become more advanced,” Nutter explains.

In practice, this means destruction must be truly irreversible, ensuring that no data-bearing component can be used to recover even fragments of information, either today or as future recovery technologies become more sophisticated.

Resources and equipment

Delivering that level of assurance requires highly specialized equipment. Purpose-built IT sanitization equipment includes shredders and degaussers that meet customer-specific or nationally recognized standards for particle size, destruction levels, and degaussing effectiveness.

Supporting this infrastructure requires dedicated facilities, trained staff, and processes for managing the resulting waste streams securely and responsibly. Control extends beyond the media being destroyed to the tools used to destroy it. As Nutter notes:

“If in a commercial setting, the machine reaches end of life, you can’t just put it in landfill or sell it on eBay – that machine has to be torn apart because any item or machine that is engaged in security processes must have a product lifecycle management (PLM) or end of life (EOL) process tied to it.”

Circularity

This level of discipline reflects the maturity of modern decommissioning programs, which increasingly balance security requirements with sustainability objectives. Many organizations now prioritize reuse, refurbishment, and recycling wherever possible to reduce e‑waste and recover residual asset value, while ensuring that security standards remain uncompromised. Some facilities have even developed processes to recover valuable materials, such as magnets from HDDs, as part of wider circular economy initiatives.

Once the fundamentals are firmly established – asset traceability, trained personnel, material security, and comprehensive audit trails – the next challenge is standardization. At hyperscale, standardization becomes the mechanism through which efficiency and accountability can be maintained as operations continue to grow.

Why standards matter in destruction

Standardization is what transforms data destruction from a site-level process into a globally scalable security function. As organizations scale across multiple facilities, regions, and teams, consistency in security controls, asset tracking, transportation, and final disposition becomes essential. Minor process failures that might be manageable in a single facility can quickly become systemic vulnerabilities when replicated across a global operation.

As destruction programs scale, organizations need a common operational framework that can be replicated. This is why many look to established government frameworks such as NIST 800‑88 and Department of Defence (DoD) guidelines, which provide detailed guidance on media classification, approved sanitization methods – including clear, purge, and destroy procedures – verification testing, witnessed destruction, tamper‑evident handling, chain of custody documentation, and long-term record retention.

Together, these frameworks create a common standard for organizations seeking to demonstrate that data has been irreversibly destroyed and that every stage of the process can withstand regulatory scrutiny.

In the US, these standards are reinforced by the National Security Agency’s evaluated product list (EPL), which lists destruction technologies that have been tested for different media types and verified to meet the classified sanitization requirements for government agencies. Achieving a place on the EPL requires manufacturers to demonstrate not only that their equipment can meet the required destruction standard, but that it can do so consistently and repeatedly under real-world operating conditions.

Moore’s Law in action

However, regulatory expectations are not static. Regulatory expectations around areas such as destruction particle size are periodically updated, with manufacturers often given a defined grace period to update and recertify equipment.

The result is a continuously advancing benchmark that pushes both equipment providers and operators to maintain the highest levels of assurance.

That evolution is becoming increasingly important as the AI era drives unprecedented growth in data generation. Modern workloads are creating and processing vast volumes of information at extraordinary speed, placing new demands on storage infrastructure and accelerating innovation in drive design.

Manufacturers are continually exploring new form factors to increase storage density, improve cooling efficiency, and maximize performance with increasingly constrained physical footprints.

As a result, drives are becoming smaller while simultaneously holding far more data. A single improperly destroyed device could expose the same amount of information stored on dozens of drives only a generation ago. As storage density continually increases, the consequences of failure become correspondingly greater.

This technological evolution introduces new challenges for data destruction programs, whereby smaller, denser storage devices can present difficulties for legacy destruction hardware, creating gaps in assurance if standards and technologies fail to evolve in parallel.

Maintaining confidence in destruction processes therefore requires continuous investment in research, testing, and adaptation, as Nutter explains:

“We’re in a position where we support commercial and enterprise customers and the government, so we’re always trying to stay ahead – whether that’s through conversations with hyperscalers, the US government intelligence community, or other agencies. That’s all fed back into R&D to stay one step ahead of the curve.”

The case for bringing data destruction in-house

As data volumes continue to grow and regulatory scrutiny intensifies, the question for many operators then turns to who should control that process.

Organizations that have spent decades destroying data at scale understand that effective decommissioning depends on maintaining visibility over every asset until its destruction is complete. While third-party ITAD providers can offer certificates of destruction, many operators argue that documentation alone cannot replace direct oversight.

Unless destruction is witnessed and verified onsite, organizations must ultimately place trust in external processes over which they have limited control. For hyperscalers and other large-scale infrastructure operators, that loss of visibility can create unnecessary blind spots at precisely the point where assurance matters most.

The appeal of outsourcing is understandable. As Nutter explains:

“It’s the path of least resistance to simply outsource that – to have a destruction firm come in, do the work, and hand over a certificate. But that comes at a cost.”

Those costs extend beyond the service fee itself. Handing responsibility to a third party introduces additional layers of logistics, security coordination, and chain of custody risks. In highly secure environments, even gaining access can be a significant undertaking.

“Going into a data center is already like going into a top-secret military site. It may take us a couple of hours just to get on site as we go through the security processes. Oftentimes, there’s a war against calling in ITADs because it’s very expensive. The better you keep machines running internally, the more money you’re saving,” says Nutter.

For hyperscalers, these considerations become magnified at scale. Operational control and financial efficiency become closely linked, where standardized internal workflows and high equipment uptime can significantly reduce reliance on external providers. Rather than introducing additional stakeholders into the chain of custody, there is the opportunity for direct control over assets from production through to final destruction.

The economics are equally compelling. If an ITAD charges $4 per drive, destroying 250,000 drives would cost approximately $1 million, with fees potentially rising to $10 per drive depending on the asset type and handling requirements. By comparison, an internally operated destruction program may cost a fraction of that amount over a similar volume, even after accounting for maintenance, replacement parts, and ongoing servicing.

Because those systems are managed onsite, organizations also retain direct control over asset disposition and any value recovered through recycling and material reclamation. According to SEM, the return on investment – measured as MOIC (multiple on invested capital) – could reach up to 29.5 times.

With security protocols and asset tracking already embedded within modern data centers, extending the same level of control to end-of-life operations represents a logical evolution. For many hyperscalers, it is worth questioning whether entrusting such a critical function to a third party is worth the operational, financial, and security trade-offs.

Lessons from five decades of secure destruction

Long before hyperscalers were retiring millions of drives each year, SEM was solving how to destroy highly classified information with absolute certainty. Since its founding in 1967, the company has focused on the secure destruction of classified data in environments where failure was not an option, working with government and defence organizations including the US Navy at a time when commercial data destruction was not yet a defined industry.

More than half a century later, that heritage continues to define SEM’s approach, particularly as commercial operators now face many of the same security expectations once reserved for governments. Many of its engineers and specialists come from government and defence backgrounds, bringing with them a culture of clearance-level rigor, procedural discipline, and hypervigilance.

That experience has helped establish a level of trust in some of the world’s most security-sensitive environments. As Nutter explains:

“Our destruction machinery is in every US embassy in the world. That credibility on the governmental side has meant that, as commercial players begin hosting government and commercial data, we carry that trust into the private sector.”

As hyperscalers, colocation providers, and enterprise data center operators increasingly manage both public- and private-sector workloads, the ability to apply government-grade destruction standards to commercial environments has become a significant differentiator.

And should organizations choose to manage this responsibility in-house to protect financial and operational integrity, SEM seeks to let it be known that they do not have to manage it in isolation.

Through experience gained from thousands of deployments worldwide, Nutter explains that several patterns have emerged among SEM’s most successful programs:

1. Training is foundational: The most effective operators rely on instructional resources, including videos, digital documentation, and instructor-led training sessions for technicians, operators, and data center managers, ensuring expertise can be scaled consistently across global operations. SEM bolsters this culture of continued education with a combination of experienced SMEs, a strong field service presence, and the ability to provide field service training to existing third-party providers for customers that require global reach.
2. Deploy a standardized approach to uptime management: Encouraging organizations to maintain dedicated toolkits, personal protective equipment, and inventories of high-use space parts directly at the point of use reduces downtime and operational disruption.
3. Experience is pivotal in informing machine selection: Different environments require different approaches, whether that involves combination systems capable of processing both SSDs and HDDs, SSD crushers that meet stringent E-4 destruction requirements, or HDD crushers designed to destroy platters while containing debris. This is why SEM is able to provide any type of data destruction device needed and is willing to customize when necessary, thanks to its experience and dedicated deployment teams.

Underlying all of this is an understanding that data destruction is not simply a technical process but a responsibility with profound operational, reputational, and human consequences. As Nutter concludes:

“Knowing that you caused harm to other companies will affect you far worse down the line than any monetary fine. People are beginning to realize that as they scale data centers, what was once the path of least resistance – outsourcing – now carries enormous risk.”

From first conversation to deployment, scaling, site training, and uptime strategies, SEM is a partner dedicated to each data destruction journey.

Ultimately, the organizations scaling most successfully are not simply destroying data securely – they are building globally repeatable, reliable systems that deliver secure, auditable destruction at industrial scale.
