KPM7WRUG3T84 Kioxia Pm7-r Series 3.84TB SAS-24GBPS Read Intensive TLC 2.5Inch Enterprise Internal SSD

Built for Read-Intensive Workloads

As a read-intensive drive, the PM7-R Series targets applications where high-speed data access is more critical than frequent writes. This makes it a suitable option for:

• Media streaming services
• Cloud-based storage
• Boot drives for enterprise servers
• Big data analytics
• Web hosting environments

Advanced SAS-4 (24G) Interface

The adoption of the 24Gbps SAS interface sets the Kioxia PM7-R series apart in enterprise storage. With this next-gen interface, the KPM7WRUG3T84 can deliver almost double the throughput of its 12Gbps predecessors, greatly reducing I/O bottlenecks in high-demand environments.

Triple-Level Cell (TLC) NAND Flash Technology

Utilizing advanced 3D TLC NAND technology, this SSD provides a balance of capacity, endurance, and performance. TLC allows the drive to offer 3.84TB of storage while maintaining consistent IOPS and read latency characteristics, making it well-suited for long-term deployment in critical systems.

Benefits of Using Enterprise SAS SSDs in Data Centers

Enterprise SAS SSDs like the Kioxia PM7-R KPM7WRUG3T84 are optimized for superior uptime, data integrity, and sustained performance. Here are some key advantages:

High Reliability and Availability

The KPM7WRUG3T84 drive supports dual-port SAS for redundancy and multi-path I/O. This ensures uninterrupted service in the event of controller path failure, which is essential in mission-critical infrastructure. Its 2.5 million hours MTTF rating adds additional confidence in operational reliability.

Scalable Architecture

With SAS-4 compatibility, this drive supports wide scalability for enterprise server and JBOD applications. Organizations can connect multiple drives in a daisy-chain architecture while sustaining high bandwidth and low latency.

Enhanced Security Options

Select versions of the Kioxia PM7-R series are available with SED (Self-Encrypting Drive) capabilities compliant with TCG Enterprise protocols. This makes the drive suitable for environments where data security and regulatory compliance are required, such as finance, healthcare, and government sectors.

Thermal Throttling and SMART Monitoring

The SSD integrates thermal throttling mechanisms that adjust performance to prevent overheating. It also supports S.M.A.R.T. attributes for proactive health and performance monitoring, allowing IT admins to detect failures before they occur.

Comparison to Other Enterprise SAS SSDs

The Kioxia PM7-R KPM7WRUG3T84 stands out in the enterprise SSD landscape for several reasons. Compared to similar models from competitors like Seagate Nytro or Western Digital Ultrastar, it delivers faster interface speeds, superior endurance for a read-intensive workload, and enhanced power efficiency.

Energy Efficiency

Kioxia has optimized the PM7-R series to consume lower idle and active power compared to its predecessors and competitors, helping enterprises reduce TCO (Total Cost of Ownership) through savings in power and cooling.

Low Latency & Fast Boot Times

With SAS-4 bandwidth and TLC NAND, the drive provides ultra-low latency on read operations, enabling faster boot times and near-instant application loading for database servers and virtualization hosts.

Application Scenarios for the PM7-R Series SSD

Virtualization Environments

In virtualized workloads where fast read access is crucial, such as VDI (Virtual Desktop Infrastructure), the PM7-R 3.84TB SSD delivers consistent performance under multi-tenant load. It supports high IOPS for read operations, reducing user latency and improving overall user experience.

Media Streaming and CDN Servers

For businesses involved in high-bandwidth content delivery, the PM7-R can handle large-scale sequential reads with minimal power draw. It’s optimized for streaming performance and helps deliver a seamless experience across geographies.

AI and Machine Learning Model Hosting

Read-intensive workloads such as model inference and data retrieval for machine learning benefit significantly from the consistent throughput of the PM7-R series. The fast access time supports real-time analytics and AI processing environments.

High-Availability Cluster Nodes

In HA cluster configurations, reliability and dual-port access are paramount. The KPM7WRUG3T84 fits this niche by ensuring sustained data access even during path failures or maintenance windows, making it ideal for active-active cluster environments.

Physical Design and Integration Considerations

Standardized 2.5-Inch Form Factor

The drive’s 2.5-inch form factor (with a 15mm height) ensures compatibility with the vast majority of enterprise storage bays and hot-swap trays. It can be deployed in traditional 2U/4U server chassis as well as high-density storage enclosures.

Hot-Swappable Design

Enterprises benefit from the hot-swappable design of SAS SSDs, allowing for easier replacement or upgrade without downtime. This supports business continuity and reduces operational interruptions during maintenance.

Backward Compatibility

While optimized for 24Gbps SAS, the PM7-R drive is backward compatible with 12Gbps and 6Gbps SAS interfaces, offering flexibility for deployment in legacy infrastructure with gradual upgrade paths.

Enterprise-Level Firmware and Error Handling

Advanced ECC and End-to-End Data Protection

Kioxia integrates robust Error Correction Code (ECC) algorithms and end-to-end data path protection, minimizing the risk of data corruption. These enterprise-grade features contribute to high data fidelity and reliability.

Power Loss Protection (PLP)

The SSD includes built-in PLP capacitors that preserve in-flight data in the event of sudden power loss. This protects against data loss and corruption, ensuring safe shutdown and recovery.

Flexible Over-Provisioning

The drive supports adjustable over-provisioning via firmware configuration tools, allowing administrators to fine-tune performance characteristics based on specific application needs.

Firmware Management Tools

Kioxia provides dedicated software tools for firmware updates, SMART monitoring, and secure erase functions. These tools simplify lifecycle management and compliance with IT best practices.
