These next-generation drives are the first enterprise SSDs built with KIOXIA’s 8th generation BiCS FLASH TLC – based 3D flash memory, which incorporates CMOS directly Bonded to Array (CBA) technology – an architectural innovation that delivers significant advances in power efficiency, performance and density, and sustainability, while doubling available capacity per flash device.
As the demands of modern computing intensify, applications such as AI, machine learning, and high-performance computing require a sophisticated solid state storage infrastructure – requiring not only enterprise-class performance but also higher power efficiency to ensure scalability and manageable operational costs.
Addressing these requirements is central to the design of the KIOXIA CM9 Series, which is purpose-built to support next-generation data centre workloads.
At the core of the CM9 Series is KIOXIA’s 8th generation BiCS FLASH, the company’s most advanced 3D flash memory to date. This technology employs a CBA-based architecture that significantly increases the NAND interface speed, enhances density and power efficiency and lowers latency – directly benefitting SSD performance.
According to KIOXIA, the CM9 Series SSDs deliver performance improvements of up to approximately 65% in random write, 55% in random read, and 95% in sequential write compared to the previous generation, the KIOXIA CM7 Series. In addition, performance-per-watt gains include approximately 55% better sequential read and 75% better sequential write efficiency.
KIOXIA CM9 Series SSD highlights include:
- PCI 5.0, NVMe 2.0, NVMe-MI 1.2c, and OCP Datacenter NVMe SSD 2.5 specification-compliant
- Dual-port support in 2.5-inch and E3.S form factors
- Read-intensive (1 DWPD) and mixed-use (3 DWPD) endurances
- Sequential performance (128 kibibytes (KiB)/QD32) – 14.8 GB/s read and 11 GB/s write
- Random performance (4KiB) – 3,400 KIOPS (QD512) and 800 KIOPS (QD32)
- 2.5-inch capacities up to 61.44 terabytes (TB) and E3.S capacities up to 30.72 TB
The KIOXIA CM9 Series SSDs are now sampling to select customers.
