Tokyo-based Kioxia Corporation, a global provider of memory and storage solutions, has announced the prototype development and customer sampling of its new KIOXIA CD9P Series SSDs, engineered to meet the rising storage demands of artificial intelligence (AI), machine learning, and high-performance computing (HPC) environments.
The CD9P Series is built on Kioxia’s 8th generation BiCS FLASH 3D flash memory, which incorporates CMOS directly Bonded to Array (CBA) technology. This architectural advancement allows the drives to double available capacity per SSD compared to their predecessors while significantly improving power efficiency and performance across key metrics. The drives are designed to help data centers maximize GPU utilization by maintaining the consistent, high-speed data throughput critical to AI and HPC operations.
Performance benchmarks reflect this design intent. The CD9P delivers sequential read speeds of up to 14.8 GB/s and write speeds of 7 GB/s, with random read and write capabilities of up to 2.6 million and 750,000 IOPS, respectively. Compared to the previous generation, the drives achieve up to 125% improvement in random write, 30% in random read, 20% in sequential read, and 25% in sequential write speeds.
The power efficiency gains are equally notable. The CD9P Series improves performance-per-watt by approximately 100% in random write operations and up to 60% in sequential read. These improvements are particularly relevant for GPU-accelerated workloads where thermal and power budgets are tightly managed.
The SSDs support PCIe 5.0, NVMe 2.0, and NVMe-MI 1.2c standards and are available in 2.5-inch (up to 61.44TB) and EDSFF E3.S (up to 30.72TB) form factors. Endurance options include both read-intensive (1 DWPD) and mixed-use (3 DWPD) configurations. The drives also support the CNSA 2.0 algorithm for future-ready data security against emerging quantum threats.
Kioxia’s new SSDs are now sampling with select customers.
