In a significant move to advance the capabilities of QLC SSDs, DapuStor has broadened its collaboration with Marvell. The partnership focuses on the integration of DapuStor's innovative Flexible Data Placement (FDP) technology, which is tailored to optimize the performance of QLC and TLC NAND SSDs. 

Known for its ability to store four bits of data per cell, QLC SSDs offer substantial capacity advantages and reduced total cost of ownership (TCO) compared to other SSD types. However, they have faced challenges such as lower endurance and slower write speeds. The FDP technology, supported by Marvell's Bravera SC5 SSD controller and DapuStor's firmware-level solutions, directly addresses these issues.

The FDP technology intelligently distributes data across QLC flash memory, optimizing the use of available storage cells and minimizing the impact of write amplification. The algorithm dynamically adjusts data placement based on workload and usage patterns, ensuring that frequently accessed data is stored in the fastest and most durable areas of the SSD. This approach enhances performance, extends endurance, and improves reliability.

Extensive testing has shown that the FDP algorithm, integrated with the Marvell Bravera SC5 SSD controller and DapuStor's firmware, can achieve a write amplification (WA) close to 1.0. A WA of 1.0 signifies that the SSD fully leverages the endurance potential of the NAND flash memory without waste. This optimization ensures that DapuStor's QLC SSD H5000 series operates at peak efficiency.

In addition to intelligent data placement, DapuStor's FDP solution incorporates advanced error correction and wear leveling technologies, further enhancing the durability and reliability of QLC SSDs. These advancements enable higher write speeds, lower latency, and extended lifespan, making QLC SSDs an ideal choice for a variety of demanding applications.

The collaboration on FDP technology follows the companies' previous joint efforts in bringing PCIe Gen 5 SSDs to market. This latest partnership marks a significant milestone in opening new possibilities for QLC applications, promising significant advancements in SSD performance and efficiency.
