Samsung Preps PCIe 5.0 QLC SSD With In-House RISC-v Controller

Quick Report

Samsung has unveiled details around its BM9K1 PCIe 5.0 QLC SSD, a new design that shifts controller architecture from Arm-based implementations to Samsung's own custom RISC-V IP. The company highlighted peak sequential read throughput of up to 11.4 GB/s and positioned the drive as part of a broader roadmap for client storage tuned for size, power, and AI-adjacent workloads.

Compared with its prior BM9C1 PCIe 4.0 QLC generation, Samsung says the new platform delivers significantly higher read performance and around 23% better power efficiency. Capacity targets currently listed are 512 GB, 1 TB, and 2 TB, with launch timing aimed at 2027. Other key metrics such as endurance and finalized write performance were not detailed, so the full real-world profile remains to be seen as specifications mature.
