Kioxia CD8-V 3.2TB U.2 PCIe 5.0 NVMe Enterprise SSD

The Kioxia CD8-V 3.2TB (KCD81VUG3T20) is a mixed-use enterprise NVMe SSD built on the PCIe 5.0 x4 interface, delivering the double-bandwidth interconnect of the fifth-generation specification through a U.2 (2.5-inch, 15mm) form factor. The drive is powered by Kioxia's BiCS FLASH 3D TLC NAND and a purpose-built enterprise controller, targeting data centers undergoing platform refreshes to Intel Sapphire Rapids, AMD Genoa, and subsequent Gen5-capable server platforms. Sequential read performance reaches up to 14,000 MB/s, with sequential write throughput up to 7,000 MB/s, representing a substantial step beyond PCIe 4.0 class storage for latency-sensitive and bandwidth-intensive server workloads.

Designed for mixed-use duty cycles, the CD8-V is rated at 3 Drive Writes Per Day (DWPD) over its rated endurance period, making it well-suited for workloads that blend read-heavy analytics with sustained write activity such as database transactions, virtual machine storage, and real-time data ingestion pipelines. The drive supports the NVMe 2.0 command set along with enterprise reliability features including end-to-end data path protection, power-loss protection circuitry, and hardware-accelerated AES-256 encryption (Self-Encrypting Drive, TCG Opal 2.0 compliant). Thermal throttling and advanced error correction via LDPC coding further underpin the drive's operational stability in high-density, always-on server environments.

The CD8-V series positions itself as a next-generation building block for storage architects planning high-performance all-flash arrays, hyperconverged infrastructure nodes, and direct-attached NVMe tiering. Its U.2 connector ensures mechanical and electrical compatibility with standard enterprise backplanes, enabling drop-in adoption within existing chassis designs while fully exploiting Gen5 host bus bandwidth. Kioxia's CD8-V lineup was introduced in Q4 2023 and has seen growing adoption in data-center refresh cycles where PCIe 5.0 host platforms have reached production readiness.

Ideal for

• High-throughput relational and NoSQL database acceleration requiring sustained mixed read/write IOPS and low queue-depth latency on Gen5 server platforms
• Virtualization host storage for hyperconverged infrastructure nodes where multiple VMs compete for simultaneous sequential and random I/O across a single high-bandwidth NVMe device
• Real-time analytics and data warehouse scratch storage where large sequential scan rates up to 14,000 MB/s compress query runtimes on in-flight datasets
• AI and machine learning training data staging, feeding GPU clusters with high-bandwidth checkpoint and dataset streaming workloads that benefit from PCIe 5.0 throughput
• Online transaction processing (OLTP) environments with mixed 70/30 read/write profiles demanding 3 DWPD endurance headroom and consistent sub-100µs latency
• Software-defined storage nodes and NVMe-oF target arrays requiring enterprise-grade end-to-end data protection, hardware encryption, and power-loss safe write caching
