With the rapid advancement of digitization and informatization, Data Acquisition Systems (DAQ) have become indispensable in industries such as industrial production, automotive electronics, aerospace, and scientific research. These systems, with their high-speed and high-precision data processing capabilities, significantly drive modern technological progress and innovation across sectors. However, as DAQ applications scale and data volumes surge, achieving efficient and rapid data storage has become a critical factor determining system performance. As a vital component, storage cards undertake real-time data storage and reliable transmission, directly impacting the efficiency and accuracy of the entire acquisition process. Selecting high-performance storage cards is essential for ensuring the efficient and stable operation of DAQ systems.

In practical DAQ system operations, storage card performance is reflected in multiple technical metrics, including storage capacity, read/write speed, latency, and stability. Among these, data storage efficiency is particularly crucial, as it directly affects the processing speed from acquisition to storage. Higher storage efficiency enhances real-time system responsiveness and ensures data integrity and reliability—especially in industrial automation and scientific research applications where minimal delays can compromise analysis accuracy or cause operational failures. Thus, achieving efficient, low-latency data storage is a key challenge in system design.
Traditional data storage methods typically require the system controller to act as a relay, transferring data from acquisition cards to storage cards. This approach not only adds transmission layers but also increases latency and potential bottlenecks. To address this, P2P (Point-to-Point) technology emerged as an innovative data transfer architecture. Leveraging high-speed switching chips, P2P technology enables direct data transfer between acquisition cards and storage cards, bypassing the controller. This design significantly shortens data paths, reduces latency and bottlenecks, and ensures efficient storage and rapid response for real-time data streams. Particularly in high-bandwidth acquisition scenarios, P2P technology stands out and has become a preferred solution for high-performance data storage.
As a professional test and measurement solution provider, Doewe Technologies launched the high-performance ASMC-PXIe-8016 PXIe Storage Card, which adopts advanced P2P technology to deliver low-latency, high-efficiency data transfer. Based on a PCIe x8 high-speed bus architecture, this card offers up to 16TB storage capacity and read/write speeds of 6.67GB/s and 6.53GB/s, meeting the demands of real-time large-scale data acquisition. In high-bandwidth, real-time-critical applications, its P2P technology ensures rapid direct data transfer, prevents data backlog in intermediate layers, and eliminates performance degradation due to latency.Additionally, the ASMC-PXIe-8016 features Doewe’s proprietary slot identification technology, enabling precise identification and management of storage modules within the chassis. This enhances data management efficiency in complex multi-module systems. The card also includes real-time energy monitoring, dynamically tracking power consumption to optimize energy management, improve system efficiency, and ensure long-term stable operation.
此外，ASMC-PXIe-8016存储卡还具备度纬科技特有的槽位识别技术，可精确标识和管理各存储模块在机箱中的位置，在多模块协同工作的复杂系统中，明显提升了数据管理的便捷性和高效性。与此同时，该产品还配备了实时能量监测功能，能够动态检测存储模块的功耗数据，帮助用户实时优化能源管理方案，提高系统整体能效，为系统长期稳定运行提供了可靠保障。
