Recently, Union Memory's new generation PCIe 5.0 enterprise SSD UH812a successfully passed the performance benchmark test of the Intel's Data Center and AI Group (DCAI) at the Intel DCAI China Key Component Verification Program, becoming the first domestic storage manufacturer being successfully verified. The test results showed that UH812a significantly outperformed mainstream competitors of the same generation in key performance indicators. Its outstanding performance and stability fully unleashed the potential of the PCIe Gen5 high-speed bus and platform memory bandwidth, and meanwhile, it strongly demonstrated the successful cooperation between Union Memory and Intel in the field of data center storage.

As an important part of the Intel DCAI China Key Component Verification Program, Intel's Benchmark aims to quantitatively evaluate the performance of computer hardware or software under specific workloads through standardized and repeatable testing methods and indicator systems. Through full-stack verification covering typical user scenarios, spanning the entire technical chain from physical layer signal integrity to application layer algorithms, it fully demonstrates Union Memory's industry-leading technical strength.

Intel DCAI China Key Component Verification Program

Intel DCAI China Key Component Verification Program aims to leverage the collaborative efforts between Intel and its partners to conduct comprehensive validation of key components (such as SSDs and memories) within servers on the Intel Xeon® platforms. This initiative evaluates design innovations as well as performance, compatibility, reliability, and functionality, facilitating the introduction of partner's latest products to end users, and aiming to jointly build an efficient, high-quality, and healthy x86 server ecosystem supply chain.

Intel's Benchmark Test: UH812a Outperforms Competitors of the Same Generation

NVMe SSD performance benchmark test aims to comprehensively evaluate the key indicators of SSDs, including reading/writing speeds, latency, and IOPS (input/output operations per second), and is an important metric for measuring the capacity of storage devices and guiding purchasing and application decisions. Through the benchmark test, the performance of NVMe SSDs under different workloads, such as sequential reading/writing and random access capabilities, can be quantified to determine if they are suitable for specific scenarios, such as high-performance computing, databases, or data center storage. In addition, the test can reveal the stability and durability of SSDs under long-term operation or high-pressure environment, helping users conduct comparative analysis across brands or models to support informed decision-making for consumers and enterprises.

Across diverse deployment scenarios, UH812a consistently delivers excellent performance

This Benchmark test covers various typical deployment scenarios, including single-drive single-port (PCIe Gen5 ×4), dual-port (2× PCIe Gen5 ×2), multi-drive concurrent access (up to 16 drives) and linear multi-drive scaling scenarios. In terms of core performance, UH812a demonstrates excellent performance consistency and leading advantages in sequential reading/ writing bandwidth, random reading/writing IOPS, 1QD command latency, and mixed workloads (70% reading operations/30% writing operations) items.

l  Outstanding Reading/Writing Performance: Union Memory UH812a, based on the PCIe Gen5 interface standard, has a sequential reading speed of up to 15,000 MB/s and a sequential writing speed of 10,500 MB/s, which are at the industry-leading level. It also performs well in random reading/writing. The 4KB random reading IOPS is as high as 3538K, and the random writing IOPS is 479K. This performance advantage can easily handle the PB-level data loading requirements in large model training, and provides extremely low latency response for real-time operation scenarios such as financial transactions, e-commerce platforms, and social interactions, ensuring fast data reading/writing and smooth operation experience.
