2.5 inch SSD Kioxia CD8-R 1.92 TB PCIe 4.0 NVMe — 7200 MB/s read, 3500 MB/s write, MTBF 2.5M h

Data Center NVMe Read-intensive SSD — the CD8-R Series is a read-intensive NVMe SSD designed for data center scale-out and cloud workloads such as big data/IoT analytics, online transaction processing and server virtualization. The drive uses a PCIe 4.0 (16 GT/s x4) interface and offers consistent random read performance up to 1,250K IOPS and random write performance up to 200K IOPS. Built on KIOXIA 112-layer BiCS FLASH 3D TLC, the 2.5-inch CD8-R delivers endurance of 1 DWPD and capacities up to 15.36 TB, suitable for hyperscale data center deployments.

Advantages

The CD8-R Series provides sustained high random-read throughput and predictable performance for read-heavy applications, along with low-latency NVMe access via PCIe 4.0. Using 112-layer BiCS FLASH 3D TLC ensures a balance of density and endurance, while the 2.5-inch form factor supports common data center server bays. With up to 15.36 TB capacity and 1 DWPD endurance, the drive fits large-scale storage tiers where read performance and capacity density are priorities.

How to use

Install the CD8-R SSD in a compatible server or storage enclosure that supports 2.5-inch NVMe drives and PCIe 4.0 lanes. Configure the drive within your storage stack or operating system following vendor best practices for NVMe devices, including firmware updates and proper partitioning. Use the drive in read-intensive tiers such as large-scale analytics, virtual machine images, and database read replicas to take advantage of its high random-read throughput and capacity density.

Recommendations

For optimal results, pair the CD8-R Series SSD with systems that provide sufficient PCIe 4.0 bandwidth and adequate cooling. Monitor drive health and firmware status regularly, and select capacity and RAID/protection schemes that match your workload’s read/write profile to ensure longevity and predictable performance.
