Kioxia Corporation has announced its new CD9P Series PCIe 5.0 NVMe SSD, explicitly designed for data center environments requiring high throughput, low latency, and consistent performance. These drives incorporate the company’s eighth-generation BiCS FLASH TLC-based 3D flash memory, integrating a CMOS directly Bonded to Array (CBA) architecture. This advanced architecture significantly improves power efficiency, thermal management, and storage density, enabling each drive to provide double the capacity compared to previous generation models.
Targeted at GPU-accelerated AI servers, machine learning, high-performance computing (HPC), and other demanding workloads, the Kioxia CD9P Series delivers substantial performance increases. Compared to the previous generation CD8P, it reports performance gains of up to 125% in random write, 30% random read, 20% sequential read, and 25% sequential write speeds. For the 15.36 TB model specifically, there is approximately a 60% sequential read, 45% sequential write, 55% random read, and 100% (2x) random write improvement in performance per watt.
The CD9P SSD supports key industry standards, including PCIe 5.0, NVMe 2.0, NVMe-MI 1.2c, and partial compliance with Open Compute Project Datacenter NVMe SSD specification v2.5. Drive form factors include 2.5-inch (15 mm thickness) and EDSFF E3.S. Capacities for the 2.5-inch format extend up to 61.44 TB, while E3.S form factor SSDs reach 30.72 TB. It is available in read-intensive (one Drive Write Per Day (DWPD)) or mixed-use (three DWPD) endurance configurations.
Sequential performance metrics specify read speeds up to 14.8 GB/s and write speeds up to 7 GB/s (128 KiB block size at queue depth 32). Random performance reaches up to 2,600 KIOPS read (4 KiB block at queue depth 512) and 750 KIOPS write (queue depth 32). Additionally, the drives incorporate Commercial National Security Algorithm Suite 2.0 (CNSA 2.0) support, specifically the Leighton-Micali Signature (LMS) algorithm for firmware protection and AES-256 data encryption, to address future threats from quantum computing.
Kioxia CD9P SSDs are currently sampling to select customers, with demonstrations scheduled for HPE Discover 2025 from June 23-26 in Las Vegas.
