Western Digital Launches Rugged 64‑Layer 3D NAND Storage for Industrial IoT

The surge in cloud adoption has shifted the focus from “where” to “how” data is stored and processed. Yet data volumes are growing explosively, driving up cloud storage costs. A single autonomous vehicle can produce several terabytes of data daily, and even non‑autonomous vehicles—thanks to dashboard cameras, ADAS, V2X, and safety sensors—contribute substantial data streams.

Industrial settings mirror this trend, propelled by the expansion of smart factories, Industry 4.0, and digital transformation initiatives.

In response, Western Digital unveiled a rugged 64‑layer 3D NAND portfolio tailored for industrial storage demands, featuring industrial‑grade eMMC, SD and micro‑SD cards. The solutions target manufacturing systems, edge‑computing platforms, drones, industrial cameras, gateways, robotics, and more.

Samuel Yu, Director of Technical Product Marketing for Western Digital’s automotive, mobile and embedded devices segment, stated, “We serve every segment that relies on data.”

Historically, data centers were the central hub for storage and processing. However, the rise of edge computing and machine‑generated data in industrial settings has spurred a shift toward storing and analyzing data nearer to its source.

Industrial players are also redefining data’s role. Yu explained, “Data was once merely a log of events; today, it’s a valuable asset for insights and actionable intelligence.”

Yu noted the rapid AI adoption: “Industrial firms are moving toward full automation, leveraging sensor fusion, analytics, and machine learning to boost productivity and efficiency.”

He emphasized, “With increased edge computing and AI, real‑time data access is essential. Storage is therefore pivotal in driving the Industry 4.0 transition.”

Western Digital’s new portfolio harnesses 3D NAND across multiple form factors.

Gartner described 3D NAND as a “disruptive technology” in 2015, noting its vertical cell architecture.

Allied Market Research projects the global 3D NAND market to reach $100 billion by 2025, growing at a 35% CAGR from its $9 billion valuation in 2017.

The portfolio introduces Western Digital’s inaugural 64‑layer eMMC variants—the iNAND IX EM132 EFD. One variant operates from –25 °C to +85 °C, while a wide‑temperature version spans –40 °C to +85 °C.

They meet the latest eMMC 5.1 specification and maintain backward compatibility, offering capacities up to 256 GB.

Yu noted, “The iNAND remains the prevalent interface for industrial embedded systems. By launching this product, we have raised capacity to 256 GB and extended product longevity.”

Yu estimates that most industrial eMMC users still rely on 2D NAND. “With 3D NAND, we can continue to satisfy the sector’s evolving needs for years to come,” he added.

Completing the lineup are the IX LD342 SD card and the IX QD342 MicroSD card, offering up to 512 GB and 256 GB of storage, respectively.

“Edge applications span a broad spectrum, and the IoT proliferation only widens that diversity,” Yu explained. “That’s why our product range supports varied temperature envelopes and multiple storage capacities.”

While Western Digital is a leading storage provider, other vendors have also launched 3D NAND solutions for industrial use.

Use cases range from traditional industrial settings to ubiquitous scenarios like security cameras and digital signage. Yu highlighted, “A security camera writes continuously, demanding high endurance, whereas a digital signage system is read‑intensive and operates differently. We collaborate closely with customers to understand these distinct requirements and tailor our portfolio accordingly.”
