DapuStor - Roealsen5 B5 SSD (EN) Dual Port

Advanced Features:

lSupport dual port

lFlash Raid 2.0 tolerating multiple flash die failures without affecting service and performance

lLatest NVMe 1.a key features

lAdvanced power loss protection that protects user data against power failure in various scenarios.

lNine levels of adjustable power consumption: more convenient operation, maintenance, and better TCO.

Superior Performance:

DapuStor R5 series PCIe Gen4 SSD offers a 100% improvement in bandwidth and IOPS performance compared with the Haishen3 series. In terms of latency, thanks to the new DP600 controller having carried out many optimisations on the IO path, the Roealsen5 series has significantly improved latency and QoS under mixed read-write scenarios.

Industry Mainstream NAND Flash:

DapuStor R5 Series is equipped with the latest 112L 3D NAND Flash from KIOXIA, realising an extremely high-power efficiency. It reduces NAND Retry at the system level through innovative machine learning technologies that predict the NAND workload in complex scenarios to prevent systemic failures.

Computing And Storage Converged Platform:

The DapuStor DP600 controller for PCIe 4.0 SSD has a built-in APPLICATION processor and the DPU-Link heterogeneous computing interface. It delivers faster speed when running Linux, conveniently transplants applications and algorithms, and improves system efficiency for database, AI, and big data applications.
