Top In-Vehicle Storage Innovations for OEMs in 2026

Cars in India are transforming from mechanical products into connected, data-heavy computing platforms. As ADAS, connected services, OTA updates, and AI-driven functions move from premium to mass-market models, in-vehicle storage has become a foundational technology decision for OEMs. Prasad Sandireddy, Vice President of Product Development Engineering at SanDisk, shares storage innovations shaping vehicle platforms in 2026 as core design considerations.

Edge Storage Essential for Indian Driving Conditions

In 2024, nearly 37% of new passenger vehicles sold in India came with embedded cellular connectivity, with numbers expected to rise significantly. However, highways, remote regions, and long intercity routes suffer from patchy network coverage, making cloud-only reliance impractical for critical vehicle systems.

Edge storage inside vehicles allows key systems to keep running, make local decisions, and respond instantly even when networks drop. For OEMs building vehicles for Indian driving conditions, robust onboard storage represents a reliability requirement rather than optional feature.

NVMe Moving from Premium to Practical

NVMe storage in automobiles was once limited to flagship ADAS systems and high-end infotainment. That perception is rapidly changing as modern cars process massive amounts of data from cameras, radar, LiDAR, and V2X systems every hour. This data arrives continuously rather than in bursts, demanding quick access for real-time processing.

NVMe SSDs rely on PCIe connections providing faster read and write speeds with reduced latency, directly improving ADAS responsiveness, AI inference at the edge, and overall system smoothness. In the near future, NVMe is likely to become standard across mid-to-high segment vehicles rather than remaining a differentiator.

Software-Defined Vehicles Drive Storage Explosion

India’s software-defined vehicle market is expected to grow rapidly from USD 2.69 billion in 2025 to over USD 9 billion by 2033. This shift changes how vehicles are built and how value is delivered over time through frequent OTA updates, feature improvements, and AI-based optimization.

According to industry estimates, future cars may require anywhere from 2TB to 19TB of onboard storage by 2030 depending on autonomy levels and feature depth. Scalable storage solutions position OEMs better for long-term innovation as vehicles evolve into upgradable platforms over their operational lifespans.

Tiered Storage Balances Cost and Performance

Not all vehicle data requires identical performance levels. Real-time sensor data and safety-critical workloads demand instant access, while logs, diagnostics, and historical data do not. This has led to growing interest in tiered hot-cold storage architectures where high-speed NVMe handles latency-sensitive tasks while cost-efficient flash storage manages long-term retention.

For OEMs, this approach offers practical benefits of better performance without pushing up system costs. Telemetry-driven storage monitoring borrowed from consumer and enterprise practices allows systems to track wear, predict failures, and optimize how data is written and moved over time.

Storage as Part of Compute Stack

With advanced ADAS, AI workloads, and autonomous features, storage has become a key component of the automobile compute stack. Emerging computational storage approaches allow certain processing tasks to happen closer to the data itself, reducing latency and easing loads on central processors for faster, more responsive systems prepared for next-generation autonomy.

For software-heavy vehicles expected to stay operational for a decade or more, intelligent storage management extends service life and reduces unexpected failures, supporting better ownership experiences. As cars evolve into data-rich, software-driven platforms, in-vehicle storage emerges as a decisive factor in real-world system performance.
