KIOXIA CD9P Series PCIe 5.0 SSDs Feature Advanced CBA Architecture and TLC Flash, Delivering Breakthrough Performance, Efficiency and Capacity

Kioxia Corporation, a world leader in memory solutions, announced the prototype development and demonstration of its new KIOXIA CD9P Series PCIe 5.0 NVMe SSDs. These next-generation drives are the latest SSDs built with Kioxia’s 8th generation BiCS FLASH TLC-based 3D flash memory. 8th generation BiCS FLASH features CBA (CMOS directly Bonded to Array) technology, a breakthrough architecture that significantly boosts power efficiency, performance, and storage density, while doubling the capacity available per SSD compared with the previous generation model.

As GPU-accelerated AI servers drive up the demands on storage infrastructure, maintaining high throughput, low latency, and consistent performance is critical — including keeping valuable GPUs highly utilized. The KIOXIA CD9P Series is purpose-built for these next-generation environments, delivering the speed and responsiveness required by AI, machine learning and HPC (high-performance computing) workloads to ensure GPUs stay fed with data and operating at maximum efficiency.

The CD9P Series leverages Kioxia’s most advanced 3D flash memory to date, featuring a CBA-based architecture that reduces heat generation, enhances thermal management, and delivers greater overall value through improved performance and power metrics and total cost of ownership.

KIOXIA CD9P Series drives deliver 4-corner performance improvements of up to approximately 125% in random write, 30% in random read, 20% sequential read, and 25% in sequential write speeds compared to the previous generation.

Furthermore, performance per watt of power consumption has improved by approximately 60% in sequential read, 45% in sequential write, 55% in random read, and 100% (2x) in random write[2]. (Applies to the 15.36 terabyte (TB) model)
