With the rapid advancement of information technology, Data Acquisition Systems (DAQ) have been widely adopted across industries, including industrial automation, scientific research, automotive electronics, and environmental monitoring. These systems undertake high-precision, high-speed data acquisition, processing, and analysis tasks in complex applications, playing a vital role in ensuring production efficiency, enhancing product quality, and driving technological innovation. As data acquisition demands grow, the performance requirements for DAQ hardware components continue to rise. In particular, the storage module has become a critical factor constraining overall system performance and application effectiveness.

In modern data acquisition systems, the storage card, as one of the core components, undertakes critical tasks. DAQ systems typically need to acquire, store, and transmit large volumes of data within short periods. The performance of the storage card directly impacts the system's stability, the accuracy of data acquisition, and the reliability of the final test results. Storage cards must not only meet the requirements for fast read/write speeds but also possess reliability and durability in extreme environments. The performance of the storage card directly determines whether the data acquisition system can complete tasks efficiently and accurately. High-performance storage cards ensure rapid and secure data storage and transmission, prevent data loss or corruption, and enhance the overall efficiency of the system. Conversely, underperforming storage cards may cause data delays, loss, or storage errors, thereby affecting the accuracy of data acquisition and even potentially leading to the failure of the entire testing process, compromising the reliability and validity of the final test results. Therefore, selecting a high-quality storage card is essential for the proper operation of the data acquisition system.
High-performance storage cards provide excellent data transfer rates and massive storage capacity, ensuring data is not lost and is efficiently preserved during acquisition. Especially in application scenarios requiring extremely high real-time performance, the read/write speed of the storage card is a key factor determining system performance. High-quality storage cards can support sustained read/write speeds exceeding 6GB/s, ensuring smooth transmission of data streams and preventing system lag or delays caused by data accumulation. Simultaneously, storage cards need to feature extremely low latency to allow the system to respond quickly to real-time data changes, ensuring every piece of data is acquired and stored in real time.
Besides transfer speed, the reliability of the storage card is equally critical. In demanding applications such as industrial and scientific research, storage cards often need to operate stably in complex environments like extreme temperatures, humidity, and high electromagnetic interference. Superior storage cards typically feature anti-interference designs and can withstand high operating temperatures and strong vibrations, providing assurance for the long-term stable operation of the system. Poor-quality storage cards may lead to data loss or storage errors, or even cause system failure, directly impacting the accuracy and validity of data acquisition results and potentially resulting in test task failures.
Doewe Technologies focuses on providing customers with high-performance, high-reliability storage solutions. Our PXIe storage card adopts advanced NVMe solid-state storage technology, featuring sustained read/write speeds exceeding 6GB/s and a maximum storage capacity of 16TB.
