Kioxia CD8 Series 2.5-Inch Up to 15.36TB 2nd Gen Data Center NVMe SSDs With PCIe 5.0

Kioxia Europe GmbH introduced its 2nd generation SSDs designed with PCIe 5.0 interface technology ^[1].

The company’s CD8 Series data center NVMe SSDs are for hyperscale data center and enterprise server-attached workloads, and utilize PCIe 5.0 interface, which doubles the bandwidth over PCIe 4.0 from 16GT/s to 32GT/s. The CD8 Series is available for customer evaluation.

Based on the firm’s 5th generation BiCS FLASH 3D flash memory technology, the CD8 Series utilizes a proprietary company’s controller and firmware, which can be customized to customer needs, and is housed in a 2.5-inch ^[2], 15mm Z-height form factor.

These drives are designed to the PCIe 5.0, Open Compute Project (OCP) Datacenter NVMe SSD 2.0 and NVMe 1.4 specifications, and are for applications and use cases that include HPC, AI, caching layer, financial trading and analysis.

“PCIe 5.0 is expected to become the dominant interface in the next two to three years,” said Paul Rowan, VP, SSD marketing and engineering. “With the introduction of the CD8 Series , Kioxia is in the ideal situation to support those customers who wish to transition earlier to PCIe 5.0.”

Additional features include:

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