FLASH SSD portfolio with high-performance data centre NVMe SSDs

KIOXIA Europe GmbH has announced the development of a prototype of its new KIOXIA CD9P Series PCIe 5.0 NVMe SSDs. These are the latest next-generation SSDs, built with the company's eighth generation BiCS FLASH TLC-based 3D flash memory. 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 used.

The series is purpose-built for these next-generation environments, delivering the speed and responsiveness required by AI, machine learning, and high-performance computing workloads to ensure GPUs stay fed with data and operate at maximum efficiency.

The series utilises the company's most advanced 3D flash memory to date, featuring a CBA-based architecture that reduces heat generation, improves thermal management, and delivers greater overall value through enhanced performance, improved power metrics, and lower total cost of ownership.

The series delivers four-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 15.36TB model)

The 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 15mm thickness, EDSFF E3.S
• Read-intensive (1 DWPD) and mixed-use (3 DWPD) endurance
• Sequential performance (128 KiB/QD32) - 14.8GB/s Read and 7GB/s Write
• Random performance (4KiB) - 2,600 KIOPS (QD512) Read and 750 KIOPS (QD32) Write
• 2.5-inch capacities up to 61.44TB and E3.S capacities up to 30.72TB
• CNSA 2.0 algorithm support

"Achieving power efficiency, whilst addressing the increasing demand for all data processing challenges for AI, machine learning or high-performance computing, is possibly the most pressing issue today and in future," says Axel Stoermann, vice president and chief technology officer for Embedded Memory and SSD, KIOXIA Europe GmbH. "At KIOXIA, we are already addressing this need by offering the CD9P Series, a leading power efficiency, high-performance solution delivering speed and responsiveness for high workloads and optimum operation."
