KPM7VRUG3T84 Kioxia 3.84TB SAS 24Gbps SSD.

Kioxia PM7-R Series Enterprise SAS SSD

The Kioxia KPM7VRUG3T84 represents the pinnacle of enterprise-grade storage technology, delivering exceptional performance, reliability, and endurance for the most demanding data center workloads. As part of the PM7-R Series, this 3.84TB SAS SSD combines Kioxia's industry-leading BiCS FLASH 3D TLC memory with a robust 24Gbps SAS interface to provide a storage solution engineered for read-intensive applications where consistent low latency and maximum uptime are non-negotiable.

The SAS 24Gbps Advantage

SAS 24Gbps operates at 22.5 Giga transfers per second (GT/s) using 128b/150b encoding, providing approximately 2,400MB/s of bandwidth per port. With dual-port capabilities, the KPM7VRUG3T84 can achieve aggregate bandwidth approaching 4,800MB/s under optimal conditions. This massive throughput ensures that storage is never the bottleneck in data-intensive environments, enabling faster data processing, reduced job completion times, and improved overall system responsiveness.

Backward Compatibility 

While featuring cutting-edge 24Gbps capabilities, the PM7-R Series maintains full backward compatibility with existing 22Gbps (SAS-4) and 12Gbps (SAS-3) infrastructures. When deployed in legacy environments, the drive automatically negotiates to the highest supported speed of the host system, protecting existing investments while providing a clear migration path to future 24Gbps infrastructure upgrades.

Performance and Real-World Capabilities

The Kioxia KPM7VRUG3T84 3.84TB SSD delivers exceptional performance metrics that translate directly to improved application responsiveness and reduced latency in enterprise environments. With carefully engineered specifications optimized for read-centric workloads, this drive establishes new benchmarks for SAS-based storage solutions.

Raw Performance Metrics

Engineered for maximum throughput, the PM7-R series delivers sequential read performance up to 1,800MB/s and sequential write performance up to 1,200MB/s. More importantly for enterprise applications, the drive achieves random read performance of up to 400,000 IOPS (4KB blocks) and random write performance of up to 70,000 IOPS. These figures represent consistent, sustainable performance under demanding workload conditions rather than burst measurements that cannot be maintained.

Enterprise-Grade Reliability and Endurance

In enterprise storage environments, reliability is not merely a feature—it's a fundamental requirement. The Kioxia KPM7VRUG3T84 is engineered with multiple layers of protection, error correction, and monitoring to ensure data integrity and drive longevity under continuous operation.

Hardware Architecture and Technical Innovation

The exceptional performance and reliability of the KPM7VRUG3T84 stem from Kioxia's sophisticated hardware architecture, which combines cutting-edge NAND flash technology with a purpose-built controller and robust firmware optimized for enterprise SAS environments.

Enterprise SAS Controller Architecture

The custom-designed controller features a multi-core processor architecture with hardware acceleration for critical functions including encryption, error correction, and wear leveling. With dedicated processing pipelines for host communication, flash management, and background operations, the controller ensures that user I/O operations receive priority while maintaining optimal flash health through intelligent background maintenance.

Compatibility

The 2.5-inch form factor with 15mm z-height makes the KPM7VRUG3T84 compatible with most enterprise server and storage enclosures designed for 2.5-inch drives. This standardized form factor ensures easy integration into existing infrastructure while providing the physical space necessary for the high-capacity flash packages and thermal management required for consistent performance.

Thermal Management and Cooling Requirements

With a typical power consumption of 8.0W during active operation and 4.5W during idle, the PM7-R Series implements sophisticated thermal monitoring and throttling mechanisms to maintain optimal operating temperatures. The drive includes multiple temperature sensors and will autonomously adjust performance if necessary to prevent overheating, ensuring reliable operation even in densely-populated storage enclosures with limited airflow.

Firmware Features and Management Capabilities

The drive supports industry-standard management interfaces including SCSI Enclosure Services (SES), SCSI Log Pages, and T10 DIF (Data Integrity Field) for end-to-end data protection. Comprehensive S.M.A.R.T. attributes provide detailed health monitoring and predictive failure analysis, enabling proactive maintenance before issues impact system availability.

Enterprise Use Cases and Application

The performance characteristics of the Kioxia PM7-R Series make it ideally suited for specific enterprise workloads where its combination of high read performance, consistent low latency, and exceptional reliability deliver maximum value.

Data Analytics

In analytics environments where large datasets are frequently queried but updated less frequently, the KPM7VRUG3T84's high read performance accelerates query processing and reduces time-to-insight. The drive's consistent low latency ensures predictable performance during concurrent query operations, making it ideal for OLAP (Online Analytical Processing) workloads and data warehouse applications.

Desktop Infrastructure (VDI)

In VDI implementations, the read-intensive nature of desktop operating system images and applications aligns perfectly with the PM7-R Series' strengths. The drive can support hundreds of virtual desktops with fast boot times and responsive application loading, while moderate write endurance accommodates user profile updates and temporary files without excessive wear.

Database Storage for Read-Intensive Workloads

For database applications with read-heavy access patterns, such as reporting databases, lookup tables, and reference data stores, the KPM7VRUG3T84 provides the low-latency random read performance necessary for efficient index traversal and query execution. The drive's advanced error correction and data protection features ensure the integrity of critical business data.

Competitive Landscape

Within the enterprise SAS SSD market, the Kioxia PM7-R Series occupies a strategic position between entry-level read-intensive drives and premium mixed-use alternatives, offering an optimal balance of performance, endurance, and cost-effectiveness for specific workload profiles.

Advantages Over NVMe SSD

While NVMe drives offer superior performance in many scenarios, SAS SSDs maintain important advantages in legacy infrastructure, shared storage environments, and applications where dual-port redundancy is required. The PM7-R Series provides a performance bridge for organizations transitioning from traditional storage architectures to next-generation solutions.
