Kioxia 3.84TB SAS 24Gbps PM7-R Series Solid State Drive

The Kioxia SDFU084DHB01T 3.84TB SAS 24Gbps PM7-R Series solid state drive (SSD) represents an advanced solution within the enterprise storage category, specifically engineered for read-intensive applications. Part of Kioxia’s renowned PM7-R lineup, this drive utilizes cutting-edge BiCS Flash TLC technology, combining high endurance with impressive performance metrics. Designed for data centers, cloud infrastructure, and mission-critical enterprise environments, the SDFU084DHB01T delivers robust storage capacity with superior reliability in a compact 2.5-inch form factor.

The Kioxia SDFU084DHB01T SSD Class

This category of enterprise internal solid state drives focuses primarily on balancing high storage capacity and read-intensive workload capabilities. The 3.84TB capacity targets data-heavy operations such as large-scale databases, virtualization, and content delivery networks where fast, sustained read speeds are essential. The use of Serial Attached SCSI (SAS) with a 24Gbps interface ensures compatibility with most enterprise servers while delivering superior throughput compared to traditional SAS SSDs.

The Kioxia PM7-R series, including the SDFU084DHB01T model, emphasizes optimized read performance, leveraging the BiCS Flash TLC memory. This triple-level cell technology integrates three bits per memory cell to maximize data density without sacrificing the endurance required in enterprise scenarios. This SSD category aims at organizations requiring a reliable, energy-efficient drive capable of handling heavy read-centric tasks with minimal latency and downtime.

Read-Intensive Enterprise SSDs

Within the broader enterprise SSD market, read-intensive drives such as the Kioxia SDFU084DHB01T serve a specific niche. Unlike mixed-use or write-intensive SSDs, read-intensive models are calibrated to handle workloads that generate significantly more read operations than writes. These workloads commonly include online transaction processing (OLTP), real-time analytics, and caching layers in distributed systems.

Because these applications stress the read path far more than the write path, the hardware and firmware optimizations in this SSD category prioritize minimizing read latency, improving random read input/output operations per second (IOPS), and ensuring data integrity over extended periods of heavy usage. This focus results in improved overall system responsiveness and uptime in demanding enterprise environments.

BiCS Flash TLC Technology

At the heart of the SDFU084DHB01T drive lies Kioxia’s proprietary BiCS Flash TLC memory. This 3D flash memory stacks multiple layers of NAND cells vertically, significantly increasing storage density and efficiency. The triple-level cell structure stores three bits per cell, which allows for larger capacities without a proportional increase in physical footprint.

BiCS Flash technology also offers enhanced endurance characteristics compared to traditional planar NAND, an important attribute for enterprise storage media. This enables the drive to maintain consistent performance and reliability across its rated lifetime, especially under read-heavy workloads where data integrity is critical.

2.5-Inch Form Factor and SAS 24Gbps Interface

The 2.5-inch size of the Kioxia SDFU084DHB01T aligns with industry-standard enterprise server drive bays, making integration straightforward for data centers upgrading storage infrastructure. The SAS interface at 24Gbps provides a robust connection protocol with enhanced error correction, multipath support, and command queuing capabilities.

This high-bandwidth interface supports sequential read speeds up to 4,200 MB/s and sequential write speeds up to 3,650 MB/s. The SAS protocol also ensures compatibility with legacy enterprise systems, providing a flexible upgrade path for organizations transitioning from traditional hard disk drives to solid-state technology.

Performance Characteristics of the SDFU084DHB01T SSD

Sustained Sequential and Random I/O Throughput

The Kioxia SDFU084DHB01T excels in delivering high sustained sequential throughput, with read speeds reaching 4,200 megabytes per second and write speeds up to 3,650 megabytes per second for 128 KiB block sizes. This performance level enables rapid data transfers during large file operations or backups, reducing bottlenecks in data center environments.

Beyond sequential transfers, the drive supports remarkable random I/O performance, especially in small block sizes typical of database and transactional workloads. The drive achieves up to 720,000 IOPS for 4 KiB random reads and 155,000 IOPS for random writes of the same size. This capability is vital for applications requiring quick access to numerous small data segments, maintaining low latency and high throughput simultaneously.

Read-Intensive Optimization

Because the drive is tailored for read-intensive environments, the firmware incorporates algorithms designed to maximize read efficiency. These optimizations reduce read amplification, improve garbage collection efficiency, and manage wear leveling specifically for scenarios dominated by read commands. The result is sustained performance consistency even under heavy multi-threaded or random read operations, extending the operational lifespan of the SSD.

Reliability and Endurance in Enterprise Environments

Mean Time To Failure (MTTF) and Drive Writes Per Day (DWPD)

Reliability is a cornerstone of the Kioxia PM7-R series. The SDFU084DHB01T offers an impressive mean time to failure of 2.5 million hours, reflecting the drive’s robust hardware design and rigorous quality control. This metric translates to a low probability of hardware failure, an essential feature for enterprise-grade storage solutions expected to operate non-stop over several years.

The drive is rated at 1 Drive Write Per Day (DWPD), a specification aligned with read-intensive workloads where writes are less frequent but data integrity remains critical. This endurance rating ensures the SSD can handle the volume of writes typical in read-focused applications without premature wear, helping IT teams maintain predictable maintenance schedules and reduce downtime.

Advanced Error Correction and Data Protection

To guarantee data accuracy and prevent corruption, the SDFU084DHB01T includes advanced error correction code (ECC) technologies. These mechanisms detect and correct bit errors on-the-fly, safeguarding data during read and write cycles. Additional enterprise features such as power loss protection and secure erase functions provide further resilience against unexpected interruptions or security threats.

Energy Efficiency and Eco-Friendly Design

Optimized Power Consumption

The PM7-R series SSDs incorporate power-saving technologies that minimize energy usage without compromising performance. This efficiency is critical in large-scale data centers where power consumption directly impacts operational costs and carbon footprint. The drive’s architecture dynamically adjusts power states based on workload demands, reducing consumption during idle or low-intensity periods.

Environmental Responsibility

Kioxia’s commitment to sustainability is evident in the eco-friendly design of the SDFU084DHB01T. Materials selection, manufacturing processes, and packaging are optimized to reduce environmental impact.
