The KIOXIA CM10 Series is Kioxia's first PCIe^® 6.0 enterprise SSD and offers direct-cold-plate liquid cooling capability, enabling more efficient cooling deployments for next-generation AI infrastructure. Compared to the previous generation⁽¹⁾, the KIOXIA CM10 Series delivers up to approx. 92 % higher sequential read performance and up to approx. 85 % higher random read performance, helping to accelerate data-intensive AI inference and enterprise applications while improving overall system efficiency.

As AI models continue to scale toward trillions of parameters and context windows expand to millions of tokens, the demand for high-performance context cache storage is growing rapidly. Architectures such as NVIDIA CMX™ extend the memory hierarchy beyond GPU memory by leveraging ultra-fast flash memory storage, making enterprise SSDs an increasingly important component of AI infrastructure. The KIOXIA CM10 Series is designed to meet these evolving requirements with the performance, capacity, and endurance needed for large-scale AI deployments.

Key features of the KIOXIA CM10 Series include:

The KIOXIA CM10 Series drives are currently sampling to select customers⁽⁴⁾, and will be showcased at FMS: the Future of Memory and Storage, taking place August 4 – 6 in Santa Clara, Calif. 

Notes:
(1): Compared to KIOXIA CM9 Series SSDs
(2): Not all requirements of the OCP Datacenter NVMe SSD specification v2.7 are supported
(3): The 2.5-inch form factor product is PCIe 5.0 compliant and uses BiCS FLASH™ generation 8 TLC flash memory
(4): These samples are for the functional check purpose only and the specifications of the samples may differ in mass production 

2.5-inch indicates the form factor name and not its physical size.

Read and write speed may vary depending on various factors such as host devices, software (drivers, OS etc.), and read/write conditions.

Definition of capacity: Kioxia Corporation 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 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.

DWPD: Drive Writes Per Day. One full drive write per day means the drive can be written and re-written to full capacity once a day every day under the specified workload for the specified lifetime. Actual results may vary due to system configuration, usage and other factors.

SED optional model supports TCG Opal SSC except for some features.
SED optional model is not available in all countries due to the local regulations.
