Challenge

5G communication systems are often installed outdoors, such as on utility poles, exposing them to extreme conditions including high temperatures, lightning, and power failures. To ensure continuous operation in these challenging environments, storage devices must be exceptionally durable and stable. Broad operating temperature range and industrial-grade protection technologies are essential to enhance device reliability and prevent failures due to temperature fluctuations or environmental stresses.

Customer Requirements

A 5G communications client set forth stringent stability requirements for SSD devices, including:

•      Extended Temperature Range: Product must operate within a temperature range of -40°C to 85°C to handle extreme heat and low temperatures.

•      Enhanced Durability: Additional protection against power outages, lightning strikes, and dust to ensure stable system operation.

•      Optimized Thermal Design: Improved heat dissipation to guarantee stable long-term operation.

Solution and Technology

To meet these requirements, we developed an SSD storage device designed for wide-temperature environments, with key technologies and solutions including:

•      Wide-Temperature Range Design: Operates from -40°C to 85°C, ensuring stability even under extreme heat.

•      Thermal Shock Testing: Simulated real-world temperature variations to ensure reliable data read/write operations in environments with large temperature fluctuations.

•      PFP (Power Failure Protection) Technology: Enhanced power-failure protection to prevent data loss during power outages or lightning events, ensuring continuous system stability.

•      Industrial-Grade Durable Components: Equipped with industrial-grade components that underwent 3000 Power Cycle tests, temperature cycling tests in high and low-temperature conditions, 100% dynamic temperature testing, and an 18-hour PCBA static burn-in test to ensure long-term stability.

•      Efficient Thermal Design: Features reinforced heat sinks and thermal materials that quickly and effectively disperse heat, ensuring stable performance during extended operation.

Application

This SSD, designed for a wide temperature range, can maintain stable data storage and processing even in harsh environments. Equipped with power-failure protection, it meets customer requirements for durability and stability. Its application has significantly enhanced overall system reliability, ensuring high-efficiency operation over long periods.

As global 5G networks continue to expand, the demand for reliability in extreme environments will only grow. This wide-temperature SSD technology will play an increasingly critical role. We are committed to further optimizing our technology to improve product durability and performance, addressing the evolving demands of the market.
