Kioxia launches 2nd generation SSDs designed with PCIe 5.0 technology

Kioxia announced that it will launch the 2nd generation SSDs designed with PCIe 5.0 technology, namely the CD8 series NVMe SSD, for data center and enterprise customers. Kioxia released the first-generation SSD based on the PCIe 5.0 specification in November last year, using the EDSFF E3.S (7.5mm) form factor for the first time in the industry.

CD8 series SSDs are based on Kioxia’s 5th generation BiCS FLASH 3D TLC flash memory and use proprietary Kioxia master control and firmware, which can be customized according to customer needs. It uses a standard 2.5-inch form factor with a thickness of 15mm. In addition to supporting the PCIe 5.0 specification of NVMe 1.4, the CD8 series SSD also supports NVMe SSD 2.0, which caters to Open Compute Project (OCP) data center requirements, making it ideal for applications in high-performance computing, artificial intelligence, cache layer, financial transactions, and analytics.

The sequential read speed of Kioxia’s CD8 series SSD is 7.2 GB/s, and the random read performance is 1.25M IOPS. It comes in two versions, one for hyperscale, server-centric read-intensive workloads, and the other for mixed-use of enterprise and write-intensive workloads. The first version is available in capacities from 960GB to 15.36TB and has a write endurance of 1 DWPD. The second version is available in capacities from 800GB to 12.8TB and has a write endurance of 3 DWPD. In addition, CD8 series SSDs are equipped with a variety of device security options like sanitize instant erase (SIE) and self-encrypted drive (SED).

Kioxia said that the CD8 series of SSDs have already provided samples to customers and are under evaluation.
