As the demands of modern computing intensify, applications such as AI, machine learning, and high-performance computing require a sophisticated solid state storage infrastructure – requiring not only enterprise-class performance, but also higher power efficiency to ensure scalability and manageable operational costs. Addressing these requirements is central to the design of the KIOXIA CM9 Series, which is purpose-built to support next-generation data center workloads.
At the core of the CM9 Series is Kioxia’s 8th generation BiCS FLASH™, the company’s most advanced 3D flash memory to date. This technology employs a CBA-based architecture that significantly increases the NAND interface speed, enhances density and power efficiency and lowers latency – directly benefitting SSD performance.
KIOXIA CM9 Series SSDs deliver performance improvements of up to approximately 65% in random write, 55% in random read, and 95% in sequential write compared to the previous generation, the KIOXIA CM7 Series. In addition, performance-per-watt gains include approximately 55% better sequential read and 75% better sequential write efficiency.
KIOXIA CM9 Series SSD highlights include (preliminary and subject to change):
KIOXIA CM9 Series SSDs are now sampling to select customers and will be showcased at Dell Technologies World, taking place May 19 – 22 in Las Vegas.
