In the context of small-capacity data storage for industrial equipment, stability and durability are often the core demands. The SD40 industrial-grade SD card (part of the Reliable Series) launched by Agrade Storage (Shenzhen) Co., Ltd. has become a high-quality storage option for embedded devices and small industrial control systems due to its compact design and strong protective performance.

Core feature: Strong configuration even with small capacity

Although positioned as a small-capacity industrial storage, the SD40 does not compromise on reliability and functionality:

Solid basic performance: Compliant with SD Card 2.0 and 1.1 specifications, it adopts an SLC cell scheme, offering capacities ranging from 256MB to 2GB. With up to 60,000 cycles of erase and write, it is paired with 24-bit/1kb ECC error correction technology, effectively avoiding errors in data transmission and storage;

Comprehensive protection features: Equipped with hardware write-protect function, it can prevent data tampering or loss caused by misoperation; at the same time, it supports SMART function, which can monitor the card's health status in real time and provide early warning of potential failures;

Strong environmental adaptability: The operating temperature range covers a wide temperature range from -40℃ to 85℃, and the storage temperature range extends to -55℃ to 95℃, making it suitable for extreme environments such as outdoor areas and low-temperature workshops. With physical protection against impact (1500G) and vibration (30G), it can also handle bumps and collisions during equipment transportation and operation.

Scenario adaptation: Precisely matching small data storage needs

The "small capacity + high reliability" characteristics of SD40 make it precisely suitable for specific industrial scenarios:

Embedded devices, such as small PLCs, smart sensors, industrial remote controls, etc., do not require large-capacity storage, but they have extremely high requirements for data stability. The 256MB~2GB capacity of SD40 just meets the storage needs for programs and a small amount of operational data;

Old industrial control systems: Some traditional industrial devices only support SD 2.0/1.1 specifications. The compatibility of SD40 can perfectly adapt to such systems, avoiding the cost pressure brought by device upgrades;

Long-running equipment: With an MTBF (Mean Time Between Failures) exceeding 3 million hours and wide voltage support ranging from 2.7V to 3.6V, it can stably serve low-power industrial equipment that operates 24/7.

Product details: Balancing practicality and durability

In addition to its core performance, the detailed design of SD40 also meets the needs of industrial scenarios:

Compact size: Adopting the standard SD card size of 24.0mm (L) × 32.0mm (W) × 2.1mm (H), it can be directly inserted into the card slots of various devices without requiring additional adaptation;

Read and write speed adaptation scenario: With a read speed of 20MB/S and a write speed of 18MB/S, although not pursuing high speed, it fully meets the read and write needs of small-capacity data, avoiding the cost waste caused by excess performance.

As a representative product of the ReliableSeries series from Agrade Storage, the SD40 fills the gap in high-quality options for industrial small data storage scenarios with its positioning of "precise adaptation + high reliability". It is an ideal storage solution for industrial users who have low capacity requirements but stringent stability requirements.
