Kioxia KCD8XVUG6T40 6.4TB NVMe 2.5-Inch Solid State Drive

SKU CH-F29G-EGY67 MPN KCD8XVUG6T40

High-capacity 6.4TB NVMe SSD delivers 7100 MBps sequential read and 6000 MBps sequential write speeds in a 2.5-inch PCIe 4.0 x4 form factor

  • 4 TB capacity stores massive datasets
  • PCIe 4.0 x4 interface enables 7100 MB/s sequential reads
  • 6000 MB/s sequential writes accelerate large-file transfers
  • 1150000 random read IOPS speeds database queries
  • 380000 random write IOPS handles heavy write workloads

Enterprise storage capacity

This Kioxia CD8-V solid state drive provides 6.4TB of storage in a 2.5-inch form factor. It uses a PCIe 4.0 x4 NVMe interface for high-speed data transfer. The drive is designed for enterprise workloads requiring consistent performance. Sequential read speeds reach 7100 MBps and sequential write speeds reach 6000 MBps.

Compatibility verification

Before ordering, confirm your server or storage array supports 2.5-inch U.2 or U.3 drive bays with PCIe 4.0 x4 electrical connections. Check that the system BIOS and backplane provide NVMe support for this form factor. Verify the thermal solution in your chassis can manage the drive under sustained write loads. Ensure your operating system includes NVMe drivers compatible with enterprise drives.

Build and connectors

The 2.5-inch form factor fits standard enterprise hot-swap drive carriers for tool-less installation. A single edge connector handles both power and PCIe 4.0 x4 data signals without separate cables. Random read performance reaches 1150000 IOPS while random write reaches 380000 IOPS for mixed workloads. The drive is new and ready for immediate deployment in compatible systems.

Questions about this item

Does the Kioxia KCD8XVUG6T40 ship with any mounting hardware or cables, or must they be purchased separately?

The drive is supplied as the 2.5-inch NVMe SSD only; mounting brackets, screws and any required cabling are not included and must be sourced separately.

The CD8-V series is only offered at 6.4 TB in this listing — how do I decide if that capacity suits my workload?

Choose the 6.4 TB CD8-V model when your application needs sustained sequential reads of 7100 MBps and writes of 6000 MBps with up to 1150000 random read IOPS and 380000 random write IOPS over a PCIe 4.0 x4 link.

What do the 7100 MBps sequential read and 6000 MBps sequential write figures mean once the drive is installed in a server?

In a PCIe 4.0 x4 slot the drive can deliver up to 7100 MBps sequential read and 6000 MBps sequential write throughput, with 1150000 random read IOPS and 380000 random write IOPS for mixed workloads.
