1. Performance Benchmark: Breaking Through Speed and Capacity in Industrial Scenarios

　　In the industrial storage sector, data throughput and response speed directly determine production line efficiency and system stability. The ST42 from Realtek Storage, leveraging the synergy of SATA Gen3 interfaces and domestic chip optimizations, establishes a performance foundation tailored for industrial applications

　　1. High-speed transmission: Breaking data bottlenecks

　　The ST42 boasts sequential read and write speeds of up to 560/510 MB/s, placing it among the top performers in the SATA interface product category. In industrial automation production lines, it enables the collection of device status data and command feedback at rates of hundreds of megabytes per second, preventing production line stalls caused by storage latency. In rail transit signaling systems, it can write high-frequency data such as train operation parameters and fault logs in real time, providing millisecond-level response support for intelligent dispatching.

　　2. Flexible Capacity: Covering Diverse Needs

　　With a flexible capacity range covering 64GB to 2TB, it meets the needs of small industrial sensors for "lightweight data storage + fast read/write" (e.g., the 64GB version suits IoT terminals) while also supporting large industrial servers for "massive data archiving + multi-task concurrency" (e.g., the 2TB version is used in smart manufacturing MES systems). This "gradient capacity" design ensures precise storage solutions for industrial equipment of varying scales.

　　3. Hardware Synergy: Reliability Upgrade

　　The ST42 features a domestically developed combination of the MediaTek MAS1102 controller and Yangtze Memory Technologies (YMTC) flash memory, achieving a "1+1>2" synergistic effect through deep optimization at the firmware layer

　　LDPC Error Correction Algorithm: Real-time repair of random errors in flash memory particles, reducing the data error rate to the 10⁻¹⁵ level, far exceeding the industrial standard of "error rate ≤10⁻¹².";

　　Intelligent Cache Scheduling: Dynamically allocates SLC cache space, boosting burst write speeds by over 3x in write-intensive scenarios (e.g., production line logging) to prevent performance degradation caused by cache exhaustion.

　　2、 Security benchmark: "data safe" for industrial grade scenarios

　　The high sensitivity of industrial data, such as military equipment parameters and power dispatch instructions, requires storage devices to have a dual security capability of "active defense+passive protection". The national industrial safety design of ST42 builds a multi-layer protective network from hardware to software:

　　1. Hardware level power-off protection: prevents data loss

　　Sudden power outages in industrial scenarios, such as unexpected power outages on production lines or fluctuations in the power grid, are the core risk of data loss. ST42 can be optionally equipped with a hardware level power-off protection module, with built-in supercapacitors and firmware power-off detection algorithm: when abnormal voltage is detected, the capacitor instantly supplies power to ensure that cached data is fully written into flash memory; Simultaneously triggering the 'write protection' mechanism, prohibiting new data from being written, and physically blocking the risk of data loss. In fields such as electricity and rail transit that have zero tolerance for power outages, this feature can reduce data loss rates to below 0.001%.

　　2. Hardware level data destruction: Dealing with extreme confidentiality

　　For "zero data leakage" scenarios such as national defense and military industry, government cloud, etc., ST42 supports hardware level physical destruction: by sending specific instructions, the "fuse circuit" inside the flash memory particles will irreversibly damage the storage unit, making data unrecoverable. Compared to software erasure (with the possibility of recovery), this physical destruction method meets the standard of "top secret data destruction" in the "Information Security Technology Data Destruction Requirements" and becomes the last line of defense for data security in critical areas.

　　3. Wide temperature adaptation: Conquering extreme working conditions

　　Industrial equipment often faces extreme temperature challenges of -40 ℃ (operating in extremely cold regions) or 85 ℃ (in high-temperature production line environments). ST42 achieves stable operation under all operating conditions through a wide temperature version hardware design (-40~85 ℃) and intelligent temperature control algorithm:

　　In low-temperature environments, the main control automatically increases signal gain to avoid flash read and write errors;

　　In high-temperature environments, dynamically adjust power consumption strategies to control device temperature within a safe range through methods such as speed reduction and optimization of heat dissipation holes.

　　In extreme scenarios such as northwest oil fields and plateau base stations, the wide temperature capability of ST42 ensures uninterrupted operation of industrial systems 24/7.

　　3、 The synergistic advantage of "safety+performance" in national industrialization

　　The "national production" attribute of ST42 is not simply a supply chain replacement, but a deep synergy of security and performance: the underlying compatibility between domestic controllers and flash memory is stronger, the firmware optimization space is larger, and a "performance security" balance strategy can be customized for industrial scenarios (such as sacrificing 5% performance for 200% data security); At the same time, the national production and supply chain has shortened the technological iteration cycle. When new demands are raised in industrial scenarios (such as higher density storage and faster destruction), Agrade Storage can cooperate with Lianyun and Changjiang Storage to quickly respond and achieve a seamless connection between "demand research and development mass production".

　　From high-speed transmission of 500MB per second, to millisecond level power outage protection, and to stable operation in extreme environments, ST42 redefines the safety and performance standards of industrial grade SSDs with "national production" as the fulcrum. In the wave of domestic substitution, this product is not only an upgrade of storage devices, but also an important infrastructure for industrial digitalization to be "independently controllable", allowing Chinese industry to take the initiative in core security in the data age.
