Read-intensive data center SSD

The Kioxia CD8-R is a 7.68TB internal solid-state drive built for scale-out and cloud workloads such as big data, online transaction processing and virtualization. It uses a 2.5-inch U.2/U.3 form factor with a 15mm height and connects through a PCIe 4.0 x4 NVMe 1.4 interface.

Thermals noise and power

The single-port design and proprietary Kioxia controller with 112-layer BiCS FLASH 3D TLC are optimised for consistent performance in 24x7 environments. Power loss protection and end-to-end data correction help maintain reliability during continuous operation.

Bundled software and accessories

Support for the Open Compute Project Datacenter NVMe SSD specification v2.0 enables integration into high-density storage deployments. The drive delivers up to 1,250K random read IOPS and 200K random write IOPS with 1 DWPD endurance for demanding read-heavy applications.

Questions about this item

Will this 2.5 inch 15mm drive fit my server bay?

The drive uses a standard 2.5 inch 15mm U.2/U.3 form factor. Verify your chassis accepts 15mm height and provides a U.2 or U.3 backplane connector.

What PCIe generation and lane width does the SSD require?

It runs on PCIe 4.0 with a x4 link (16 GT/s per lane). Your motherboard or backplane must supply a PCIe 4.0 x4 slot or U.2/U.3 port wired for x4.

How much daily write endurance does the 7.68TB model provide?

The drive is rated for 1 DWPD, meaning you can write the full 7.68TB capacity every day for the warranty period.
