Tokyo – The first vendor to offer a drive designed with PCIe® 5.0 interface technology[1], Kioxia Corporation today announced that it has built on this achievement by introducing its 2nd generation SSDs. The company’s new KIOXIA CD8 Series data center NVMe™ SSDs (“CD8 Series”) are optimized for hyperscale data center and enterprise server-attached workloads, and utilize PCIe 5.0 interface technology, which doubles the bandwidth over PCIe 4.0 from 16 gigatransfers per second (GT/s) to 32GT/s. The CD8 Series is now available for customer evaluation.

KIOXIA CD8 Series: 2nd Generation SSDs Designed with PCIe® 5.0 Technology for Enterprise and Hyperscale Data Centers

Based on Kioxia’s 5th generation BiCS FLASH™ 3D flash memory technology, the CD8 Series utilizes a proprietary Kioxia controller and firmware, which can be customized to customer needs, and is housed in a 2.5-inch[2], 15mm Z-height form factor. The new drives are designed to the PCIe 5.0, Open Compute Project (OCP) Datacenter NVMe SSD 2.0 and NVMe 1.4 specifications, and are well-suited to applications and use cases that include high-performance computing, artificial intelligence, caching layer, financial trading and analysis.

Additional features include:

  • Read-intensive 1DWPD (Drive Write Per Day) endurance models targeted for hyperscale and server-centric workloads, in capacities from 960GB to 15.36TB
  • Mixed-used 3DWPD endurance targeted models are available, in capacities from 800GB to 12.8TB
  • Delivers up to 1.25M random read IOPS and 7.2GB/s sequential read throughput, an improvement of approximately 14% over the previous generation version[3]
  • Security options include sanitize instant erase (SIE) and self-encrypted drive (SED) [4]

  • The sample drives are for evaluation purposes. The specifications of the sample drives may differ from the production drive models.

  • Definition of capacity: Kioxia 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 bits = 1,073,741,824 bits, 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 speeds are the best values obtained in a specific test environment at Kioxia Corporation and Kioxia Corporation warrant neither read nor write speeds in individual devices. Read and write speed may vary depending on the device used and file size read or written.
