Kioxia Corporation, one of the world’s leading memory solutions, announced on June 19th 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 utilised. 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% in 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. (Applies to the 15.36 terabyte (TB) model)
KIOXIA CD9P Series SSD highlights include (preliminary and subject to change):
- PCIe 5.0, NVMe 2.0, NVMe-MI 1.2c compliant
- Open Compute Project Datacenter NVMe SSD specification v2.5 support (Not all requirements)
- Form factors: 2.5-inch 15 mm thickness, EDSFF E3.S
- Read-intensive (1 DWPD) and mixed-use (3 DWPD) endurances
- Sequential performance (128 KiB/QD32) – 14.8 GB/s Read and 7 GB/s Write
- Random performance (4KiB) – 2,600 KIOPS (QD512) Read and 750 KIOPS (QD32) Write
- 2.5-inch capacities up to 61.44 TB and E3.S capacities up to 30.72 TB
- CNSA 2.0 algorithm support
(Prepared for the threat posed by quantum computers)
KIOXIA CD9P Series SSDs are now sampling to select customers and will be showcased at HPE Discover 2025, taking place June 23-26 in Las Vegas.
