YANSEN’s DOM SSD: Extensive Application in Industrial Environments

DOM(Disk on Module) solid state drive, as a compact, efficient, and stable data storage solution, offer significant advantages over traditional SSD technology. They feature a more miniaturized design, providing plug-and-play convenience and high compatibility, making them suitable for various scenarios such as embedded systems, industrial control systems, and servers.

Stability and Reliability 

Having undergone extensive development and optimization, DOM products exhibit exceptional stability and reliability. These devices typically incorporate industrial-grade designs and materials, ensuring they can maintain consistent and reliable performance over extended periods, even when subjected to harsh environmental conditions. DOM generally uses original MLC (Multi-Level Cell) and SLC (Single-Level Cell) chips to better ensure stability and reliability. Compared to consumer-grade DOM, which often use TLC (Triple-Level Cell) and QLC (Quad-Level Cell) chips, MLC and SLC chips are more capable of maintaining performance without slowdown in high-temperature and industrial environments. Additionally, because the lifespan of SLC chips is hundreds of times greater than that of TLC and QLC chips, industrial-grade DOM has a significantly longer lifespan.

Long-term Supply and Compatibility

In traditional industrial and embedded systems, DOM has become a standard and widely accepted storage solution. Both suppliers and users have grown accustomed to integrating and utilizing DOM products in their operations. These devices benefit from stable and well-established production processes, along with robust supply chain support, ensuring consistent long-term availability and compatibility. This stability in production and supply chains not only guarantees a reliable source of components but also facilitates seamless integration and maintenance, making DOM an ideal choice for various industrial and embedded applications. Consequently, the widespread adoption of DOM in these sectors underscores its reliability, ease of use, and the confidence both manufacturers and end-users place in its performance.


Compared to newer storage technologies such as UFS (Universal Flash Storage) and eMMC, DOM generally offers a more cost-effective solution. This makes them particularly appealing for cost-sensitive applications where budget constraints are a significant consideration. DOM is especially advantageous in scenarios that require smaller storage capacities and straightforward data management. For example 4GB~64GB is the mainstream capacity range in the six-axis robotic arm applications. If a fault occurs during the production process, the repair costs for eMMC onboard storage products are very high. However, with DOM plug-in hard drives, new components can be easily replaced, significantly reducing both repair costs and time.

Ease of Design and Integration

DOM typically utilizes standard interfaces and dimensions, such as SATA or embedded USB interfaces, which significantly enhance their convenience for design and integration. DOM’s compatibility with these standard interfaces allows them to be directly inserted into motherboard slots or connected to system boards, reducing design and wiring complexity. This plug-and-play functionality not only simplifies the overall system architecture but also accelerates the development process, enabling faster time-to-market for new products.

Industry-specific Requirements

In certain industries applications, such as industrial control and medical equipment, DOM has become a standard storage solution that complies with specific industry standards and regulatory requirements. These sectors have stringent demands for stability, long-term supply, and compatibility, all of which are critical for maintaining reliable and consistent operation. The high level of reliability and compliance provided by DOM products ensures they meet the rigorous expectations and operational guidelines of these industries.

DOM can be considered a relatively mature technology in the storage industry, having been in existence for very long period market verification. Initially, DOM found extensive application in embedded systems and industrial control systems, where there was a need for a small, stable, and highly reliable storage solution. Emerging embedded storage solutions such as eMMC and UFS have gradually replaced DOM in certain application contexts due to their higher performance and larger storage capacities. However, as an established technology in the storage industry, DOM continues to maintain a certain market demand and position in specific industrial and embedded applications. Its advantages lie in stability, reliability and cost-effectiveness.


YANSEN provides SATA DOM, PIN IDE DOM, and USB DOM, with SATA DOM leading the lineup due to its stable performance and high product quality, consistently receiving praise both domestically and internationally.

YANSEN’s SATA DOM products incorporate advanced technologies such as PSLC, AES 256 Encryption, Quick Erase, and Conformal Coating, ensuring high-performance delivery. Providing temperature ranges of 0°C to 70°C, -20°C to 75°C, and -40°C to 85°C, they can be paired with MLC to enhance product compatibility. Additionally, the products can be paired with CNC housings to improve protection, enhance heat dissipation, and extend product lifespan, addressing more specialized and complex application needs.

By adopting a locked BOM (Bill of Materials) scheme, YANSEN ensures consistency and quality in the assembly of SATA DOM products, enhancing production efficiency and effectiveness.

YANSEN’s SATA DOM products are widely used in fields such as medical, automation, and industrial control systems. And they are continuously sold to customers worldwide, where they are used in medical devices, subway turnstile and large-scale production equipment such as six-axis robotic arm.

YANSEN will continue its commitment to technological innovation, providing customers with one stop industrial storage solutions.
