• 32GT/s transfer rate per lane
• Backward compatibility with PCIe 4.0 systems
• Enhanced signal integrity for improved reliability
• Optimized power efficiency despite increased performance

NVMe 1.4 Compliance Enterprise Feature Set

The CD8-R Series implements the NVMe 1.4 specification, incorporating enterprise-focused features that enhance performance, reliability, and manageability in data center environments.

Enterprise NVMe Features

• Multi-path I/O with namespace sharing
• Predictable Latency Mode for consistent performance
• Enhanced thermal management capabilities
• Sanitize commands for secure data disposal

KCD8XPUG1T92 Model Specifications

The Kioxia KCD8XPUG1T92 offers 1.92TB of usable capacity in the industry-standard 2.5-inch form factor, making it compatible with existing enterprise server and storage infrastructure while delivering next-generation performance.

Endurance and Write Performance

While optimized for read-intensive applications, the KCD8XPUG1T92 maintains robust write capabilities with sequential write speeds up to 7,000 MB/s and random write performance up to 400,000 IOPS. The drive offers a endurance rating of 1.3 DWPD (Drive Writes Per Day) over its 5-year warranty period.

Read-Intensive Workload Optimization

The CD8-R Series is specifically engineered for applications where read operations significantly outnumber write operations, typically in ratios of 70:30 or higher. This optimization enables cost-effective performance for a wide range of enterprise use cases.

Database Servers

In database environments, the CD8-R Series accelerates query processing, reporting, and analytics workloads. The high random read performance significantly reduces query response times for both OLTP and OLAP systems.

Form Factor and Compatibility

The 2.5-inch form factor with U.3 interface (backward compatible with U.2) ensures broad compatibility with existing enterprise servers, storage arrays, and JBOD systems.

NVMe Management Interface

Standard NVMe management commands enable remote monitoring, configuration, and firmware updates through popular data center management tools.

Security Features

Enterprise data security is paramount, and the CD8-R Series incorporates multiple security technologies to protect sensitive information.

Sanitize Operations

The drives support multiple sanitize methods, including cryptographic erase, block erase, and overwrite, enabling secure data disposal when repurposing or decommissioning drives.

Environmental Specifications

The drives are designed to operate reliably in typical data center environments with operating temperatures from 0°C to 70°C and non-operating temperatures from -40°C to 85°C. They can withstand vibration levels typical of multi-drive server and storage configurations.

Comparison with Other Enterprise SSD Categories

The CD8-R Series occupies a strategic position in Kioxia's enterprise SSD portfolio, optimized specifically for read-intensive workloads.

vs. Mixed-Use SSDs

Compared to mixed-use SSDs, the CD8-R Series offers superior read performance and cost-effectiveness for applications where write operations are less frequent.

vs. Write-Intensive SSDs

While write-intensive SSDs prioritize write endurance and performance, the CD8-R Series delivers better read performance at a lower cost per gigabyte for read-dominant workloads.

Future-Proofing Your Storage Infrastructure

With the transition to PCIe 5.0 in server platforms, the CD8-R Series provides a forward-looking storage solution that will not become a bottleneck as CPU and memory performance continue to advance.
