Performance Characteristics

The KCM7-R Series SSD is optimized for read-intensive workloads, providing consistent performance with ultra-low latency. PCIe Gen5 NVMe 2.0 doubles theoretical bandwidth compared to Gen4, enabling high-speed data transfers across multiple enterprise applications. Workloads that rely on rapid data retrieval, including OLTP databases, cloud applications, AI inference, and high-volume content delivery, benefit from the drive’s predictable read performance and minimized response times.

Sequential Read Throughput

Sequential read operations, commonly required in data analytics, large-scale backups, and streaming workloads, benefit from the high bandwidth of PCIe Gen5. The KIOXIA 1.92TB SSD delivers sustained throughput, allowing organizations to move and process large datasets efficiently while maintaining optimal server utilization.

Workload Optimization

• Cloud computing environments requiring high-speed read access.
• Virtualized infrastructure with read-heavy VDI workloads.
• AI/ML inference and analytics pipelines that demand low latency.
• Caching layers and metadata servers for accelerated application response.
• Content delivery networks (CDNs) supporting high-volume read requests.

Endurance and Reliability

Rated at 1 DWPD, the KIOXIA CM7-R Series SSD is designed for predominantly read workloads while providing reliable endurance and long-term performance. Advanced error correction (ECC), wear-leveling algorithms, and over-provisioning ensure data integrity and extend drive longevity. This makes the drive suitable for critical enterprise operations requiring predictable performance and minimal downtime.

Power Loss Protection

To safeguard in-flight data during unexpected power outages, the KCM7-R Series includes capacitor-backed power-loss protection. Metadata and pending write operations are safely committed to non-volatile memory, preventing data loss and maintaining enterprise data integrity.

Error Correction and Monitoring

• Advanced ECC algorithms correct bit errors and prevent data corruption.
• End-to-end data protection ensures accuracy during read and write operations.
• SMART telemetry provides real-time health monitoring, including temperature, power cycles, and endurance metrics.
• Background management routines maintain steady-state performance for consistent enterprise-grade reliability.

Security Features

The SIE (Self-Encrypting Enterprise) technology embedded in the CM7-R Series provides robust hardware-based AES-256 encryption, securing all data-at-rest without affecting performance. Cryptographic erase capabilities allow rapid, secure retirement of drives, simplifying compliance and lifecycle management.

Encryption and Compliance

• Hardware-based encryption reduces CPU overhead compared to software encryption.
• Supports integration with enterprise Key Management Systems (KMS) for secure key handling.
• FIPS 140-2 compliance ensures adherence to regulatory standards.
• Cryptographic erase functionality enables secure decommissioning of drives.

Enterprise Compliance Benefits

SIE functionality supports regulatory and internal compliance requirements, making the CM7-R Series suitable for finance, healthcare, government, and other industries that demand secure data handling and auditability.
