Kioxia CD9 Series PCIe 5.0 NVMe Enterprise SSD

The Kioxia CD9 Series is a mainstream enterprise NVMe SSD built on the PCIe 5.0 x4 interface, purpose-engineered to satisfy the throughput and latency requirements of modern data center deployments. Leveraging Kioxia's BiCS FLASH 3D TLC NAND technology and a high-performance NVMe 2.0-compliant controller, the CD9 delivers sequential read speeds reaching approximately 14 GB/s and sequential write speeds up to 10 GB/s — effectively doubling the bandwidth ceiling established by PCIe 4.0 predecessors. The drive is available in the industry-standard U.2 (2.5-inch, 15 mm) and E3.S form factors, enabling broad compatibility across contemporary server platforms from major brands.

The CD9 Series is architected for general-purpose enterprise server workloads, including virtualization, cloud-native application hosting, relational and NoSQL database operations, and high-throughput object storage. It incorporates end-to-end data protection with T10 DIF/DIX support, hardware-accelerated AES-256 XTS self-encrypting drive (SED) capability compliant with TCG Opal 2.0, and power-loss protection circuitry that safeguards in-flight data during unexpected power events. The drive's QoS-optimized firmware ensures predictable latency under sustained mixed-read/write queue depths, making it reliable in shared, multi-tenant server environments.

Kioxia positions the CD9 as the successor to the CD7 Gen4 line, maintaining consistent enterprise-grade reliability with a rated endurance of up to 3 DWPD for write-intensive capacities while offering 1 DWPD variants optimized for read-dominant workloads. The series supports NVMe Management Interface (NVMe-MI) for out-of-band management integration and is compatible with industry-standard monitoring and telemetry frameworks, giving data center operators granular visibility into drive health, wear, and I/O performance across large-scale deployments.

Ideal for

• Accelerating relational database engines (MySQL, PostgreSQL, Oracle) where sequential and random I/O throughput directly impacts query response times and transaction commit latency
• Powering virtualization hosts running VMware vSphere or KVM with dense VM populations that demand consistent low-latency storage I/O across concurrent workloads
• Supporting cloud-native Kubernetes persistent volume claims in hyperconverged infrastructure nodes requiring high bandwidth for distributed storage backends such as Ceph or Rook
• Enabling high-performance object storage clusters where PCIe 5.0 throughput eliminates storage as the bottleneck in multi-petabyte S3-compatible deployments
• Serving as primary NVMe storage in AI and machine learning training pipelines for rapid dataset ingestion and checkpoint writing during model training runs
• Underpinning log aggregation and time-series analytics platforms that ingest high-velocity streaming data and require sustained sequential write performance at scale
