Topping the Charts with Leading Growth

In an industry landscape where PCIe SSDs already account for 87.5% of total market capacity, Union Memory achieved a breakthrough with its flagship PCIe 5.0 products. Its share of total capacity in the PCIe SSD segment increased by 4.1 percentage points year-over-year to 16.4%. This performance has established a significant first-mover advantage in the construction of AI computing infrastructure, continuously solidifying the growth momentum of the top domestic storage brand.

Meanwhile, in the SAS SSD segment, Union Memory also ranked first among domestic manufacturers with a 26.8% market share, leveraging the high stability and reliability of its products. This demonstrates comprehensive leadership across multiple interface technology routes, positioning it as the preferred domestic mainstream SAS storage solution for enterprise users.

Full-Stack Strength, Covering All Domains

Union Memory has achieved full coverage of the three major enterprise interface protocols—PCIe, SAS, and SATA—building a complete matrix of full-scenario storage solutions.

• Flagship Leader: Enterprise PCIe 5.0 SSD (UH8 Series)

Targeting scenarios such as AI training and inference, and high-performance computing, this series doubles performance compared to the previous generation. It offers leading read/write throughput and ultra-low latency, has passed multiple Intel certifications, and serves as a core support for AI computing infrastructure.

• Balanced Choice: Data Center SSD (UH7 Series)

Designed for diverse scenarios including AI, large-scale cloud, virtualization, and big data, this series relies on an excellent energy efficiency ratio and enterprise-grade reliability (MTBF ≥ 2.5 million hours) to optimize customer TCO.

• Agile Choice: Enterprise M.2 Boot Drive (UM301a)

Specifically designed for rapid server deployment and boot scenarios, this drive adopts a DRAM-less architecture. While ensuring reliable booting, it achieves lower power consumption and better cost. Unaffected by supply fluctuations, it provides a highly flexible and cost-effective entry-level foundation for enterprise systems.

• Rock-Solid: High-Performance SAS SSD (UH6 Series)

Tailored for demanding scenarios like financial transactions, this series uses a SAS 3.0 dual-port architecture and offers two endurance options: 1 DWPD and 3 DWPD, providing users with exceptional performance and data security.

• Foundation Choice: Mainstream SATA SSD (UM3 Series)

Targeting cost-sensitive scenarios such as warm/cold data storage and server boot drives, this series offers high cost-effectiveness as a practical solution for large-scale data deployment.

Ecosystem Collaboration, Building the Future Together

Beyond continuous product iteration and deep technological innovation, Union Memory persistently cultivates ecosystem development, collaborating with industry leaders to pioneer new storage solutions for the intelligent computing era. Through a deep strategic partnership with Intel, Union Memory has achieved milestone breakthroughs at the ecosystem level.

• Authoritative Certification: Union Memory’s PCIe 5.0 products passed Intel’s BKC certification and PCIe link stability tests with “zero defects,” becoming the first domestic SSD manufacturer to obtain Intel’s SPDK, VROC, and OPEA three authoritative technical verifications, gaining comprehensive recognition for its technical depth.
• Joint Innovation: Union Memory, together with partners like Intel, jointly released a dual-path cold plate full-liquid cooling server, deeply integrating the UH812a liquid-cooled SSD to set a new benchmark for data center heat dissipation. Additionally, both parties launched a high-performance storage solution based on Intel Xeon 6 processors and the UH812a, as well as a white paper on network storage solutions combining RDMA and NVMe technologies.

From self-developed controller chips to a full-stack product matrix and deep ecosystem collaboration, Union Memory has built a formidable technological moat that is difficult to replicate. With the explosion in AI inference demand, the enterprise SSD market is poised for a new golden cycle. Union Memory will continue to deepen ecosystem partnerships, creating more efficient, reliable, and greener storage foundations for global data centers, helping accelerate the release of data potential across industries.
