SSD disk Kioxia 6.4 TB 2.5 inch PCI Express 5.0 NVMe CM7-V

The Kioxia CM7-V SSD delivers enterprise-class NVMe storage in a 2.5" form factor with 6.4 TB usable capacity. Designed for mixed-use workloads, this drive uses PCI Express 5.0 and NVMe 2.0 (U.3 hosts use PCIe 4.0) to provide very high sequential transfer rates — up to 14,000 MB/s read and 6,750 MB/s write — and strong random IOPS performance for demanding server and workstation tasks. Built with Kioxia 112-layer BiCS FLASH 3D TLC memory, the CM7-V balances performance, endurance and density for applications that require sustained throughput and reliable write endurance.

Advantages

The CM7-V combines a large 6.4 TB capacity in a standard 2.5" enterprise form factor with PCIe 5.0 bandwidth to support heavy mixed read/write workloads. BiCS FLASH TLC provides efficient density and durability while NVMe 2.0 and optimized firmware enable low latency and high IOPS. This SSD is engineered to deliver consistent sequential and random performance, making it suitable for latency-sensitive environments where both throughput and endurance matter.

Suitable for

• Enterprise servers handling mixed read/write databases and online transaction processing (OLTP)
• High-performance computing and analytics nodes that require sustained sequential throughput
• Media streaming and content delivery systems that demand high read bandwidth
• IoT and edge computing devices with intensive local storage requirements
• Workstations used for video editing, rendering, and large dataset manipulation

How to use

Install the SSD into a compatible 2.5" U.3/PCIe NVMe slot or adapter according to your server or workstation documentation. Ensure the host supports the appropriate PCIe generation: PCIe 5.0 for full bandwidth or PCIe 4.0 for U.3 hosts. Configure the drive in the system BIOS/UEFI and initialize it in the operating system storage manager. For enterprise deployments, integrate the device into existing RAID, software-defined storage, or volume management solutions and enable vendor-recommended firmware and monitoring tools.

Recommendations

Use the CM7-V for workloads that require a balance of high sequential bandwidth and sustained random IOPS. Monitor drive health and firmware updates using vendor utilities, provision adequate cooling in server bays to maintain performance, and follow capacity planning best practices to avoid write amplification and to preserve endurance.
