The KIOXIA CM10 Series delivers up to 92% higher sequential read performance and up to 85% higher random read performance, helping to accelerate data-intensive AI inference and enterprise applications while improving overall system efficiency.
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 generation1, the KIOXIA CM10 Series delivers up to approx. 92% higher sequential read performance and up to approx. 85% higher random read performance2, 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 agentic AI context windows expand to millions of tokens, the demand for high-performance KV (Key Value) cache storage is growing rapidly. The NVIDIA CMX solution extends effective GPU memory with a shared, pod-level context tier optimized for ephemeral KV cache. By leveraging ultra-fast flash storage, CMX makes 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:
- Available in E3.S, E1.S, and 2.5-inch form factors3, with cold-plate liquid cooling capability in E3.S and E1.S 9.5 mm form factors. (all form factors support traditional air cooled environments)
- Capacities ranging from 1.60 TB to 61.444 (varies by form factor), with read-intensive (1 DWPD) and mixed-use (3 DWPD) endurance options5.
- PCIe 6.0, NVMe™ 2.1, and Open Compute Project® (OCP®)6 Datacenter NVMe SSD Specification 2.7 compliant, including support for NVMe Flexible Data Placement (FDP).
- Utilizes leading-edge KIOXIA BiCS FLASH™ generation 10 (332-layers) flash memory that improves SSD performance and power efficiency.
- Security options include SIE, SED, SED FIPS 140-3 (planned)7,8, post-quantum cryptography, CNSA 2.0, and SPDM 1.4 attestation support.
“As AI infrastructure evolves, storage must deliver not only higher performance but also greater efficiency and deployment flexibility,” said Neville Ichhaporia, senior vice president and general manager of the SSD business unit at KIOXIA America, Inc. “The KIOXIA CM10 Series reflects our continued commitment to advancing flash storage that helps customers build more capable, scalable, and efficient AI infrastructure.”
The KIOXIA CM10 Series drives are currently sampling to select customers9, and will be showcased at FMS: the Future of Memory and Storage, taking place August 4 – 6 in Santa Clara, Calif.

Information in this press release, including product pricing and specifications, content of services, and contact information is current and believed to be accurate on the date of the announcement, but is subject to change without prior notice. Technical and application information contained here is subject to the most recent applicable Kioxia product specifications.
Notes:
1: Compared to KIOXIA CM9 Series SSDs
2: Read and write speed may vary depending on various factors such as host devices, software (drivers, OS etc.), and read/write conditions.
3: The 2.5-inch form factor is PCIe 5.0 compliant and uses KIOXIA BiCS FLASH™ generation 8 TLC flash memory.
4: 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.
5: 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.
6: Not all features of the OCP Datacenter NVMe SSD specification v2.7 are supported.
7: SED optional model supports TCG Opal SSC except for some features.
8: SED optional model is not available in all countries due to the local regulations.
9: These samples are for the functional check purpose only and the specifications of the samples may differ in mass production.
