DapuStor® DP800 Series PCIe Gen5 enterprise SSD controller chip (DP800) enables enterprises and data centers to achieve high-performance, high-capacity SSDs (Solid State Drives) using next-generation NAND technology. The DP800 series includes two product models, DP816 and DP808, and supports the standard NVMe (NVM Express) interface, optimized for high-performance 4K random read and write operations and all on-chip flash memory management operations, while minimizing the use of host processing and memory resources. DP800 supports ultra-high performance, high-capacity enterprise-grade SSDs, and has platform flexibility and security, making it a reliable choice for enterprise-grade SSD controller chips.
PCIe SSDs with NVMe controllers can greatly improve the storage performance of enterprises and data centers by enabling faster random data access and faster transfer rates, alleviating interface bottlenecks.
The DapuStor DP800 controller chip series is an NVMe-compliant PCIe enterprise flash controller that significantly improves read and write performance while also significantly reducing latency and power consumption. The DP800 controller chip series will bring significant innovation to the next-generation storage and computing system architecture, creating more value for users.
