Product Overview

The KIOXIA PM7-R 3.84TB Enterprise SSD (KPM7WRUG3T84) represents KIOXIA's flagship read-intensive solid-state drive designed for the most demanding enterprise and hyperscale storage environments. Built around the 24Gb/s SAS (Serial Attached SCSI) interface and housed in a compact 2.5-inch form factor, this drive delivers the combination of extreme throughput, sustained low latency, and carrier-grade reliability that modern data centres require. As one of the world's leading NAND flash manufacturers, KIOXIA leverages its proprietary BiCS FLASH 3D TLC NAND technology to produce a drive that consistently outperforms competing solutions in read-dominant workloads, making it a preferred choice for enterprise IT architects, cloud service providers, and storage administrators across the GCC region and beyond.

The PM7-R series is purpose-built for scenarios where data is read far more frequently than it is written — such as content delivery, database query serving, analytics, and virtualised server farms. By optimising the drive's endurance profile and internal firmware for sequential and random read operations, KIOXIA achieves a balance of high capacity, superior performance, and long operational lifespan that is difficult to match in the 24G SAS segment.

Key Features & Benefits

• 24Gb/s Dual-Port SAS Interface: The PM7-R operates on the 24Gb/s SAS-4 standard, doubling the bandwidth of legacy 12G SAS environments and ensuring full compatibility with modern SAS-4 HBAs and expanders. Dual-port connectivity provides redundant data paths for maximum availability in mission-critical HA configurations.
• 3.84TB High-Density Capacity: With 3.84TB of usable storage per drive, organisations can maximise rack density and reduce the total number of drives needed in large-scale deployments, directly lowering capital expenditure and power consumption per terabyte.
• KIOXIA BiCS FLASH 3D TLC NAND: Proprietary 3D stacked NAND architecture delivers a superior balance of density, endurance, and cost efficiency, enabling the PM7-R to sustain high read throughput over its entire operational lifetime without performance degradation.
• Read-Intensive Optimisation: Firmware and over-provisioning are tuned specifically for read-dominant workloads, enabling the drive to deliver consistently high IOPS and throughput under sustained queue depths without the latency spikes associated with write-heavy mixed-use drives.
• End-to-End Data Protection: Comprehensive T10 PI (Protection Information) support, internal ECC, and power-loss protection circuitry ensure data integrity from host to NAND, guarding against silent data corruption and unexpected power events that are common concerns in 24/7 enterprise environments.
• Advanced Security Features: Full disk encryption (FDE) with AES-256 and SED (Self-Encrypting Drive) support enables compliance with stringent data-at-rest regulations, including those relevant to financial services, government, and healthcare sectors across the Middle East and GCC.
• High MTBF and Field-Proven Reliability: Rated for 2.5 million hours MTBF, the PM7-R is engineered for continuous operation in 24/7 enterprise environments, minimising unplanned downtime and reducing total cost of ownership over multi-year deployment cycles.
• SCSI Persistent Reservations & Sanitize Commands: Enterprise-class management features including persistent reservations, format unit, and sanitize ensure seamless integration with enterprise storage arrays, SAN fabrics, and storage management software.

Technical Architecture

At the core of the KIOXIA PM7-R is a highly integrated SSD controller paired with KIOXIA's own BiCS FLASH 3D TLC NAND. The BiCS FLASH architecture stacks memory cells vertically in multiple layers, dramatically increasing areal density while improving the power efficiency of each read and write cycle. The result is a drive that achieves high capacity without the physical footprint expansion associated with planar NAND scaling.

The internal firmware implements advanced read-retry algorithms, dynamic thermal management, and wear-levelling strategies that are specifically calibrated for read-intensive drive life profiles. The drive's DRAM cache — used for mapping tables and read-ahead buffers — is protected by a dedicated power-loss protection (PLP) circuit, ensuring that in-flight data and metadata survive sudden power interruptions without corruption.

The 24Gb/s SAS interface is implemented with dual SAS ports, each capable of operating independently. This dual-port architecture allows the drive to be simultaneously connected to two separate SAS HBAs or expanders, providing hardware-level path redundancy. Storage array controllers can leverage both paths for load balancing in active-active configurations or failover in active-passive HA setups. The SAS protocol's support for tagged command queuing (TCQ) and advanced error recovery ensures that the PM7-R integrates cleanly into enterprise SAN environments managed by leading storage operating systems.

KIOXIA's PM7-R also implements the SAS-4 defined Zoned Block Commands (ZBC) awareness and is compliant with the T10 SCSI command set, making it broadly compatible with storage stacks that rely on standard SCSI semantics. The drive's self-monitoring (SMART) extensions provide rich telemetry data to storage management tools, enabling predictive failure analysis and proactive maintenance.

Performance & Capacity

The KIOXIA PM7-R 3.84TB delivers industry-leading performance figures for the 24G SAS read-intensive category. Sequential read throughput reaches up to 4,200 MB/s, while sequential write throughput is rated up to 1,800 MB/s, making the drive exceptionally capable for large-block streaming workloads such as media serving, backup repositories, and data analytics pipelines.

For random I/O — the benchmark most relevant to transactional and virtualised workloads — the PM7-R achieves up to 800,000 IOPS random read and up to 200,000 IOPS random write at 4K block sizes, sustaining these figures under high queue depths typical of enterprise SAN environments. Latency is tightly controlled, with average read latency well under 200 microseconds, ensuring that application response times remain consistent even under peak load.

The drive carries an endurance rating of 1 DWPD (Drive Writes Per Day) over a standard five-year operational period, confirming its read-intensive positioning while still providing sufficient write endurance for mixed enterprise workloads that involve periodic batch writes, log flushing, or snapshot operations. Total Bytes Written (TBW) for the 3.84TB model is approximately 7 PBW (Petabytes Written), a figure that comfortably covers the lifecycle requirements of most read-dominant enterprise deployments.
