The first vendor to offer a drive designed with PCIe 5.0 interface technology, Kioxia Corporation recently announced it has built on this achievement by introducing its second generation SSDs. The company’s new KIOXIA CD8 Series data centre NVMe SSDs (CD8 Series) are optimised for hyperscale data centre and enterprise server-attached workloads, and utilise 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.
Based on Kioxia’s 5th generation BiCS FLASH 3D flash memory technology, the CD8 Series utilises a proprietary Kioxia controller and firmware, which can be customised to customer needs, and is housed in a 2.5-inch, 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 percent over the previous generation version.
- Security options include sanitise instant erase (SIE) and self-encrypted drive (SED).
