The Vanishing Roadmap

Obsolescence, NAND Shortages, and the New Reality of Supply Chain Volatility 

The global computing industry is entering a new period of instability, defined by two converging forces: accelerating end-of-life (EOL) cycles and tightening memory and storage supply. Together, these factors are transforming how systems are designed, manufactured, and supported throughout their operational lifetimes. For organisations that depend on predictable component availability, the implications are significant. 

At Captec, we are seeing these pressures first-hand through our work designing and supporting application-specific computing platforms for long-life and mission-critical environments. As lifecycles shorten and availability tightens, system engineering and supply chain management have become inseparable disciplines. The ability to anticipate and mitigate risk early in the design process is now essential to sustain continuity and compliance across extended operational programmes. 

A Decade-Long Squeeze on Memory and Storage

After a brief era of low prices and abundant supply, the world’s memory and storage markets have reversed course. Manufacturers of NAND flash, DRAM, and SSD or NVMe drives are now facing the tightest supply conditions seen in years. What began as a cyclical correction following the oversupply of 2022 and 2023 has evolved into a structural shortage that many analysts believe could persist well into the next decade. 

At the centre of this shift lies the explosive growth of artificial intelligence. Training and deploying large-scale models require vast quantities of high-performance memory and storage. Each processing node can consume hundreds of gigabytes of DRAM and multiple terabytes of flash. The scale of this demand has disrupted global allocation. Major hyperscale operators are reserving supply years in advance, securing entire production runs of NAND and high-bandwidth memory before they reach distribution. Smaller integrators and OEMs are facing fluctuating prices, limited availability, and lead times that change from week to week. 

Compounding the issue, investment is being redirected towards higher-margin technologies such as high-bandwidth memory and advanced 3D NAND for enterprise customers. Conventional products, including DDR4 and TLC NAND, are being phased out more quickly than demand is falling. This is creating shortages in mainstream segments that once provided stability. With both flash and hard drives now constrained at the same time, there is no longer an alternative market to absorb demand spikes. 

Early End-of-Life: When the Roadmap Becomes Unreliable 

Another major challenge facing the industry is the rapid acceleration of component EOL cycles. Several high-profile semiconductor manufacturers have shortened their product roadmaps or withdrawn established lines earlier than planned. In many cases, these decisions are driven by the same upstream pressures that affect memory and controllers rather than by commercial choice alone. 

Even when a component remains officially active, the parts that support it may not be. Once a single critical element such as a NAND die, power management IC, or memory interface becomes unavailable, the product must be withdrawn. For sectors such as defence, medical, energy, and transport, where systems undergo lengthy qualification and certification, these early withdrawals create major programme risks. Redesign, revalidation, and requalification all take time and resources that can far exceed the price of the part itself. 

The Rise of Allocation Risk and Grey Market Exposure

In today’s market, availability has become more critical than price. Manufacturers now allocate supply through controlled channels, and allocation decisions can change within days. It is increasingly common for the same component to vary in cost by more than twenty percent within a short period, depending on timing and allocation status. 

This volatility is being felt across the supply chain, with margin erosion already evident in some areas. Sampling of open orders has shown cost pressures equivalent to a two to five percent impact, largely due to the pace of change and competition for constrained allocations. Authorised distribution channels are struggling to meet demand in full, while alternative sourcing routes must now be explored with care. 

At Captec, we are mitigating these risks through comprehensive due diligence, verifying the integrity and provenance of all sourced parts before deployment. We are scouring global supply networks to identify new opportunities while maintaining full traceability to safeguard quality and compliance. Our procurement teams are also re-quoting on a weekly basis to reflect current market conditions and ensure pricing accuracy at the point of order confirmation. This approach allows us to protect customers as much as possible from cost shocks and availability fluctuations, even in a volatile global environment. 

Engineering for Continuity

For businesses operating in long-lifecycle or safety-critical environments, effective obsolescence management is now an engineering discipline in its own right. It requires early visibility of component risks, continuous monitoring of supplier roadmaps, and proactive planning to secure alternatives well before shortages emerge. Design flexibility, once a desirable feature, has become essential to ensure continuity.

At Captec, we apply an engineering-led approach to these challenges, combining lifecycle forecasting, traceable sourcing, and in-house validation and testing. Our multidisciplinary teams bring together mechanical, electrical, and computing hardware specialists who work collaboratively to identify risks early and design resilient pathways through them. By managing redesigns, substitutions, and compliance testing under one roof, we help customers maintain operational continuity and minimise programme disruption.

Captec also works closely with customers to ensure transparency around pricing and allocation realities. By confirming part availability and costs at the time of order receipt, we enable customers to make informed decisions before acceptance, supporting business continuity and avoiding unexpected changes later in the project lifecycle. This integrated approach supports performance, compliance, and reliability, even when market conditions are unpredictable.

From Volatility to Stability: The Path Forward

The convergence of AI-driven demand, limited fabrication capacity, and shortened product lifecycles has exposed a fragile equilibrium in the global technology supply chain. New fabrication facilities are under construction, but they will take several years to reach full production. Geopolitical uncertainty and shortages of key materials continue to complicate expansion plans.

Until supply stabilises, volatility will remain the norm. Organisations that treat lifecycle management as a strategic function, integrating supply intelligence, engineering adaptability, and partnership-based risk management, will be best placed to maintain performance in an uncertain market.

Through its integrated engineering, manufacturing, procurement, and lifecycle management capabilities, Captec continues to support customers in navigating these pressures with foresight and control. We are using our global sourcing network and Group procurement leverage to secure verified parts wherever possible, helping to minimise the impact of rising costs and reduced availability. By aligning technical understanding with proactive supply management, we ensure that critical systems remain operational, compliant, and dependable throughout their intended lifetimes.

The era of cheap, abundant memory and stable component roadmaps has ended. The next decade will reward foresight, collaboration, and the ability to engineer for resilience in a world where continuity can no longer be assumed.
