Capacity and role

This Kioxia CD8-R provides 15.36TB of read-optimised NVMe storage in a 2.5-inch 15mm U.2/U.3 drive. It targets data-centre workloads such as big data, online transaction processing and virtualisation. The 112-layer BiCS FLASH 3D TLC and single-port controller are built for consistent 24x7 operation.

PCIe 4.0 interface limits

The drive uses a PCIe 4.0 x4 link compliant with NVMe 1.4 and supports the Open Compute Project Datacenter NVMe SSD specification v2.0. Random read reaches 1,250K IOPS and random write 200K IOPS. Endurance is rated at 1 DWPD. Power loss protection and end-to-end data correction protect data integrity.

Compatibility checklist

Confirm the host system provides a U.2 or U.3 backplane slot that accepts a 15mm 2.5-inch drive and can supply PCIe 4.0 x4 signalling. Verify the platform firmware recognises NVMe 1.4 devices and that power delivery meets the drive’s requirements. Ensure the operating environment supports continuous 24x7 operation.

Questions about this item

Will this drive fit in a standard 2.5-inch U.2/U.3 hot-swap bay?

Yes, it uses the 2.5-inch 15mm form factor designed for U.2 and U.3 bays, so it fits standard enterprise hot-swap trays that accept 15mm drives.

What does 1 DWPD mean for daily write workloads?

It guarantees you can write the full 15.36TB capacity every day for the warranty period, which suits read-heavy tasks like analytics, virtualization and transaction processing.

Does the drive include hardware protection against sudden power loss?

Yes, it features built-in power-loss protection and end-to-end data path correction to preserve in-flight data during unexpected outages.
