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

Western Digital has announced a new line of ruggedized, 64‑layer 3D NAND storage designed for the demanding environments of industrial IoT (IIoT), edge computing, and automotive applications.

As cloud‑based data analytics become increasingly abstract, the sheer volume of data generated by autonomous vehicles, smart factories, and connected devices is forcing companies to rethink where and how data is stored and processed. A single autonomous vehicle can produce several terabytes of data each day, and even vehicles that are not fully autonomous generate massive amounts of data from cameras, driver‑assist systems, V2X communications, and safety sensors.

Similarly, the industrial sector is seeing a rapid shift toward Industry 4.0, smart factories, and digital transformation, which in turn drives demand for storage that is reliable, high‑capacity, and capable of operating in harsh conditions.

Western Digital’s new portfolio includes industrial‑grade eMMC devices, SD cards, and micro‑SD cards. The offerings cover a wide range of temperatures—from –25 °C to +85 °C for standard models and –40 °C to +85 °C for the wide‑temperature version—making them suitable for manufacturing systems, edge‑computation hardware, drones, industrial cameras, gateways, robotics, and more.

“We are engaged in all segments that need and thrive on data,” said Samuel Yu, director of technical product marketing for Western Digital’s automotive, mobile and embedded devices segment.

Traditionally, data centers were the central hub for storage and processing. However, the rise of edge computing and the explosion of machine‑generated data in industrial settings have created a growing need to store and process data closer to its source.

Yu explained that the definition of data is evolving: “Data used to be a log where you just record an event,” he said. “But now, people see data as an opportunity to gain insight and to reap value from it.”

He added that artificial intelligence is proliferating across industrial operations. “More industrial companies are pursuing full automation of their operations, while broader numbers use sensor fusion, analytics and machine learning to drive productivity and efficiency,” Yu said.

“The important thing to remember is that as you get more compute at the edge and more AI, you need access to data in real‑time,” he said. “Storage plays a critical piece of that, and we see storage playing a critical role in enabling the Industry 4.0 transition.”

Western Digital’s 3D NAND portfolio spans multiple form factors. In 2015, Gartner hailed 3D NAND as a “disruptive technology” because it allows memory cells to be built vertically.

Allied Market Research projects that the global 3D NAND market could reach $100 billion by 2025, growing at an annual clip of 35%. For context, the market was valued at roughly $9 billion in 2017.

The flagship product, the iNAND IX EM132 EFD, is the company’s first 64‑layer eMMC variant. It is available in two temperature variants: a standard model for –25 °C to +85 °C and a wide‑temperature model for –40 °C to +85 °C. The devices comply with the latest eMMC 5.1 standard and offer backward compatibility. Capacities range up to 256 GB.

“The iNAND is the most common form interface today for embedded systems in the industrial space,” Yu said. “We’ve achieved two key goals with this launch: first, we’ve pushed capacity to 256 GB; second, we’ve extended the lifespan of these products.”

Yu noted that most industrial eMMC deployments have used 2D NAND. “With 3D technology, we’ll continue to meet the demands of the space in the upcoming years,” he said.

Complementing the eMMC line, Western Digital also introduced the IX LD342 SD card and the IX QD342 microSD card. The SD card offers up to 512 GB of storage, while the microSD supports up to 256 GB.

“The spectrum of requirements at the edge is wide. The applications are diverse,” Yu said. “That’s why the product line supports a wide range of temperatures and a broad set of storage capacities.”

While Western Digital is one of the largest storage companies, other vendors are also bringing 3D NAND to industrial applications. Use cases span from traditional industrial settings to ubiquitous devices such as security cameras and digital signage. “If you have a security camera, it’s writing to the storage 24 × 7, so you need something that is rated for high endurance,” Yu explained. “If you have a digital signage system, you’re reading from it 24 × 7; it’s a read‑intensive application, so the requirements differ.” He added, “We work with our customers to understand the requirements and all these different applications, and we have built our portfolio to serve those needs.”
