KIOXIA Introduces New PCIe 5.0 SSDs for Enterprise and Data Center Infrastructures

New KIOXIA CD8P Series Single-Ported NVMe Drives Optimized for Performance, Latency and Quality of Service in E3.S, 2.5-Inch Form Factors

SAN JOSE, Calif., August 7, 2023 – KIOXIA America, Inc. today announced the addition of the KIOXIA CD8P Series to its lineup of data center-class solid state drives (SSDs). KIOXIA CD8P drives are well-suited to general purpose server and cloud environments that can take advantage of PCIe® 5.0 (32 gigatransfers/s x4) performance. These data center applications can generate complex mixed workloads spread across large scale virtualized systems. The new drives are available in capacities up to 30.72 terabytesi (TB) and in both Enterprise and Data Center Standard Form Factor (EDSFF) E3.S and 2.5-inch (U.2) form factors.

Optimized for the performance, latency, reduced power and thermal requirements of data center environments where power and cooling efficiency is critical, the KIOXIA CD8P Series provides the predictability and consistency needed for a seamless user experience. According to Jeff Janukowicz, Research Vice President, IDC, “Growth in NVMeTM SSDs continues with PCIe capacity shipments in servers and storage systems expected to grow at a 40% CAGR between 2022 and 2027. The new CD8P Series SSDs gives these customers the range of performance, capacity, and security choices essential for meeting the storage requirements of next-generation digital enterprise and data center infrastructure.”

KIOXIA CD8P drives realize an approximately 60% to 80% increase in sequential read performance when compared to previous generation PCIe 4.0 SSDs*, including:

  • Random readii performance up to 2,000K IOPS and random writeii performance up to 400K IOPS
  • Low and consistent 99.999th percentile latency of under 250us in standard random read workloadsiii, and under 1.8ms in standard OLTP-style mixed workloadsiv

The new 5th generation data center drives are based on the KIOXIA BiCS FLASH™ 3D flash memory triple-level cell (TLC) technology, and utilize an in-house developed controller.  KIOXIA CD8P Series SSDs are compliant with PCIe 5.0 and NVMe 2.0 specifications as well as the NVMe Management Interface (NVMe-MI™) v1.1d, and support Open Compute Project (OCP) Datacenter NVMe SSDv specification (not all requirements).

“We are proud to introduce our latest data center PCIe 5.0 NVMe SSD, for general-purpose server and cloud applications,” said Neville Ichhaporia, senior vice president and general manager of the SSD business unit, KIOXIA America, Inc. “The CD8P Series is ready for next-gen PCIe 5.0 servers, delivering a great combination of high performance with low latency in both E3.S and 2.5-inch form factors.”

Additional features include:

  • Full data reliability with end-to-end data protection, power loss protection and flash die failure recovery
  • Available SED models support TCG Opal and Ruby SSCsvi

Definition of capacity: KIOXIA Corporation defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 2^30 bytes = 1,073,741,824 bytes and 1TB = 2^40 bytes = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.

Read and write speed may vary depending on the host device, read and write conditions, and file size.
