Cheetah Storage Class Memory (SCM) are high-reliability, high-performance PCIe Gen5 x4 NVMe 2.0 SSDs designed for next-generation enterprise and data center storage. Rated for up to 60 DWPD for random workloads and 80 DWPD for sequential workloads, Cheetah SCM delivers the endurance needed for sustained, high-intensity data operations. With 16 NAND channels and a DDR5 interface, it also delivers ultra-low latency and high random IOPS for demanding AI and data center workloads. This combination of endurance and performance makes Cheetah SCM a differentiated storage solution in the QLC era of high-capacity storage. Cheetah SCM bridges the performance and persistence gap between memory and traditional NAND flash, providing significantly higher storage capacity than DRAM while maintaining fast, consistent access to critical data. Available in U.2, E1.L, E1.S, and E3.S form factors, Cheetah SCM provides a flexible, high-integrity storage platform for next-generation enterprise and data center architectures.

Benefits
- Accelerate AI and Data-Intensive Workloads: Cheetah SCM SSD is designed for applications where high bandwidth alone isn’t enough. Its combination of ultra-low latency, high random IOPS, and predictable QoS enables faster access to critical data for AI training and inference, GPU workloads, and other performance-sensitive applications.
- Bridge the Gap Between Memory and Storage: Cheetah SCM occupies the performance tier between DRAM and traditional NAND flash. It provides persistent storage with substantially higher capacity than DRAM, enabling more hot data to remain immediately accessible without requiring the cost and capacity limitations of memory-only architectures.
- Deliver Consistent, Predictable Performance: For latency-sensitive workloads, average performance isn’t enough. Cheetah is engineered to provide consistent response times and strong QoS, helping reduce performance variability and keep demanding applications running predictably under sustained workloads.
- Optimize the AI and Hot-Data Tier: Cheetah is ideally suited for AI model checkpointing, GPU scratch space, GPU Direct Storage, vector databases, metadata acceleration, journaling, high-frequency transaction logging, and low-latency caching – workloads where rapid access to persistent data can directly impact system efficiency.
- Deploy Flexibly Across Data Center Architectures: Available in U.2, E1.L, E1.S, and E3.S form factors, Cheetah provides a scalable storage architecture for diverse enterprise platforms. A common controller and firmware approach across form factors can simplify platform development.
