KIOXIA America, Inc. announced the development and prototype 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. KIOXIA 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 high-performance computing (HPC) 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, power metrics and total cost of ownership. With an increased focus on power and performance efficiency (performance per watt), the CD9P Series 15.36 TB model delivers approximately 60% and 45% improvements in sequential read and write speeds per watt, respectively, compared to the previous generation SSD. It also achieves gains of approximately 55% and 100% in random read and write performance per watt, measured in thousands of IOPS (KIOPS), respectively.

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

KIOXIA CD9P Series SSD highlights include:

·PCIe 5.0, NVMe 2.0, NVMe-MI 1.2c compliant
