/PRZWT/Recently, Yilian officially launched its first QLC SSD product for the consumer market - AE531. This product is built on QLC NAND medium, with outstanding ecological compatibility and full life cycle cost optimization as its core competitiveness. It provides innovative storage solutions for consumer-grade PCS, laptops and other terminal devices, setting a value benchmark for consumer-grade storage products.
Stabilize the architecture and reshape the golden balance between performance and cost
The AE531 is equipped with the new generation controller from Yilian, combined with an intelligent IO acceleration module and a mature and stable third-generation firmware architecture. It can achieve sequential read and write speeds of up to 688/5600 MB/s, as well as 4K random read and write IOPS of 700K/800K, with performance comparable to TLC products.
Meanwhile, for lightweight loads and complex hybrid read-write scenarios, AE531 innovatively integrates three core technologies:
Ultra-low latency architecture: Based on the SOC hardware acceleration module, it achieves lower latency in the QD1(queue depth 1) scenario, meeting the demand for rapid response to real-time performance
2. Dynamic resource Scheduling: By coordinating the HMB mechanism (host memory buffering) with the main control algorithm, dynamic optimization of data streams and intelligent scheduling of cache resources are achieved, significantly enhancing the efficiency of mixed read and write operations
3. Long-lasting performance guarantee: The static SLC caching strategy breaks through the lifespan limitations of traditional SLC simulations, ensuring stable peak performance throughout its life cycle
To achieve a balance between high performance and low cost, AE531 adopts the page interleaved block RAID algorithm. By leveraging multi-channel data interleaved distribution and redundancy check mechanisms, it significantly enhances the utilization rate of flash memory particles, greatly improves data reliability, and effectively reduces the unit capacity cost. In addition, relying on an efficient firmware architecture, the AE531 also features adaptive resource management functions such as deep optimization of instruction queues and intelligent garbage collection (GC) strategies, which can reduce performance fluctuations while extending the lifespan of flash memory chips.
In the actual test of PCMark 10, compared with the same-level products of mainstream domestic competitors, AE531 leads in nearly 90% of the test items, with an overall score exceeding 3800, which is nearly 11% higher than that of its competitors.

Reliability and TCO define the long-term value of storage
AE531 has been verified through over 7,000 rigorous test cases, including more than 1,000 hours of high-temperature and high-pressure challenges, 500 hours of EST test verification, and over 6,000 violent start-stop experiments, etc. Comprehensive and full life cycle test coverage ensures that the product's average mean time between failures (MTBF) exceeds 2 million hours.
Through the DRAM-less architecture design and the high-density advantage of QLC medium, the hardware cost per unit capacity can be reduced by 30% compared with TLC products of the same level. The low power consumption (PS4+L1.2) is less than 2.5mW, with a prominent energy consumption advantage. AE531 adopts an intelligent power consumption management strategy, which can dynamically adjust the power consumption of the main control and flash memory according to the workload. The battery life of the notebook platform is extended by up to 16%, especially helping users of thin and light laptops achieve both performance and energy efficiency.
In terms of long-term usage cost, AE531 achieves multi-dimensional monitoring of SMART health status, erase and write cycles, temperature, and error rates through an enhanced SSD log system, combined with self-developed intelligent analysis engines and other tools. It predicts potential faults, reduces the risk of data loss and unexpected downtime losses, and provides strong support for the operation of various applications.
Full ecological adaptation builds a solid storage foundation
In terms of ecological compatibility, AE531 demonstrates outstanding cross-platform collaboration capabilities. It has been fully adapted to mainstream CPU platforms both at home and abroad, and has achieved deep compatibility with over ten operating systems including Windows, Linux, Chrome, and domestic open-source ecosystems. Its certification system covers multiple dimensions such as technical specifications, security standards, and mainstream ecosystems. We have built a dual-track support capability for the product that is compatible with both international common architectures and emerging systems.
For data security, AE531 supports the national encryption algorithms SM2/SM3/SM4, which can meet the security encryption requirements of scenarios such as finance and government affairs. On this basis, the product supports differentiated customization services and can quickly deploy hardware-level encryption modules or custom firmware functions according to user needs.
As an industry technology trendsetter, AE531 was the first to lay out technologies such as RPMB and QLC FNV(Fast NVMe), not only achieving hardware-level security protection but also significantly enhancing the collaborative efficiency between SSDS and hosts through protocol layer optimization, strengthening the adaptability to diversified scenarios such as edge computing and smart terminals.
According to TrendForce's prediction, QLC flash memory will account for 22% of the total flash memory shipments in 2025, which is more than three times the proportion of QLC flash memory shipments in 2021. Driven by the continuous growth in demand for business office work, creative production and entertainment experiences, the popularization process of QLC is accelerating. The launch of Yilian AE531 precisely follows this trend and responds to the constantly improving demand for storage performance in daily applications.
This time, Yilian is reconfiguring the value of storage with QLC technology. It not only pursues performance challenges but also pays attention to the comprehensive cost throughout the user's entire life cycle. Through technological innovation, it breaks through the bottlenecks of traditional storage solutions and provides users with a new integrated storage experience of "high adaptability + optimal TCO", truly benefiting hundreds of millions of end users.
