KIOXIA CM10 PCIe 6.0 Enterprise SSD
KIOXIA CM10 is the company's first PCIe 6.0 enterprise SSD family, built around BiCS FLASH generation 10 TLC and aimed at enterprise plus AI workloads that need higher performance and cooling flexibility.
CM10 should not be treated as a normal retail SSD today. KIOXIA says the drives are sampling to selected customers, and this page only displays a Buy/View Price path when a current public offer exists.
| SSD | Capacity | Interface | NAND | Form factor | Commercial status | Current price |
|---|---|---|---|---|---|---|
| KIOXIA CM10 AI inference, KV cache, enterprise application processing and software-defined storage | Up to 61.44TB | PCIe 6.0 on EDSFF; 2.5-inch is PCIe 5.0 NVMe 2.1 | BiCS FLASH generation 10 TLC | E3.S / E1.S / 2.5-inch | Sampling Samples are being provided to selected customers. | Not yet available |
CM10 capacity and form factors
CM10 is not one capacity or one physical shape. KIOXIA lists E1.S, E3.S and 2.5-inch configurations, with read-intensive and mixed-use endurance classes. The EDSFF versions carry the PCIe 6.0 label; the 2.5-inch versions are listed as PCIe 5.0.
| CM10 configuration | Workload | PCIe / NVMe | Capacities | Endurance | Form factor |
|---|---|---|---|---|---|
| CM10-R E1.S | Read intensive | PCIe 6.0 NVMe 2.1 | 3.84 / 7.68 / 15.36TB | 1 DWPD | E1.S 9.5mm liquid/air; E1.S 15mm air |
| CM10-R E3.S | Read intensive | PCIe 6.0 NVMe 2.1 | 3.84 / 7.68 / 15.36 / 30.72 / 61.44TB | 1 DWPD | E3.S liquid/air |
| CM10-V E3.S | Mixed use | PCIe 6.0 NVMe 2.1 | 3.2 / 6.4 / 12.8 / 25.6 / 51.2TB | 3 DWPD | E3.S liquid/air |
| CM10-R 2.5-inch | Read intensive | PCIe 5.0 NVMe 2.1 | 1.92 / 3.84 / 7.68 / 15.36 / 30.72TB | 1 DWPD | 2.5-inch |
| CM10-V 2.5-inch | Mixed use | PCIe 5.0 NVMe 2.1 | 1.6 / 3.2 / 6.4 / 12.8 / 25.6TB | 3 DWPD | 2.5-inch |
CM10 performance
KIOXIA describes CM10 as delivering substantial gains over CM9 in sequential read and random read performance under its stated comparison. DatacenterDisk treats those as manufacturer claims, not independent benchmarks, and does not rank CM10 by value until a current public price exists.
CM10 liquid cooling
Liquid cooling is a platform feature, not a universal deployment setting. KIOXIA lists cold-plate direct liquid cooling support for E3.S and E1.S 9.5mm CM10 form factors, while all form factors also support traditional air-cooled environments according to its product material.
CM10 for AI inference and context cache
CM10 sits in the high-performance enterprise flash tier. It is relevant to AI inference, context cache, vector-index backing stores and data pipelines that are sensitive to latency and throughput. It is not simply a higher-capacity archive drive.
CM10 and NVIDIA CMX
KIOXIA positions CM10 around NVIDIA CMX context memory storage, where a fast shared flash tier can support ephemeral KV cache. That does not mean CM10 replaces GPU memory; it means fast enterprise SSDs can become part of a broader memory and storage hierarchy.
CM10 vs CM9
| Interface | CM10 EDSFF moves to PCIe 6.0 / NVMe 2.1; CM9 is a PCIe 5.0 generation. |
|---|---|
| NAND | CM10 uses BiCS FLASH generation 10 TLC, while CM9 used earlier BiCS TLC. |
| Cooling | CM10 adds direct-cold-plate support on selected EDSFF form factors. |
| Availability | CM10 is sampling to selected customers; CM9 is an established enterprise SSD generation. |
