Kioxia CM7-R 30.72TB U.2 PCIe NVMe SSD 

Designed in the industry-standard 2.5-inch U.2 form factor, the CM7-R series SSD integrates seamlessly into modern enterprise server infrastructures. Supporting PCIe Gen4 x4 and NVMe 1.4 specifications, the drive significantly enhances input/output operations per second (IOPS), sequential bandwidth, and response consistency. The massive 30.72TB storage capacity allows organizations to consolidate workloads, reduce rack space utilization, and improve overall storage density while minimizing power consumption per terabyte.

As a read-intensive enterprise SSD, the CM7-R is optimized for applications requiring frequent data retrieval with moderate write workloads. This makes it especially suitable for content delivery networks, cloud storage systems, analytics engines, media repositories, and large-scale web hosting environments. Its enterprise-class firmware includes advanced reliability features such as power loss protection, end-to-end data path protection, namespace management, and robust error correction mechanisms.

Enterprise-Class PCIe Gen4 NVMe Performance

One of the defining strengths of the Kioxia SDF3080DAB01T CM7-R 30.72TB SSD is its exceptional sequential performance. Leveraging PCIe Gen4 x4 connectivity, the drive can deliver dramatically improved bandwidth over previous PCIe Gen3 solutions, enabling faster data movement across demanding enterprise environments.

Sequential read speeds can exceed enterprise expectations, making the drive highly effective for large file transfers, backup acceleration, data lake retrieval, streaming analytics, and virtual machine deployment. Organizations managing large unstructured datasets can benefit from reduced latency during file access and significantly faster processing pipelines.

Optimized Random IOPS

In addition to sequential throughput, the CM7-R provides impressive random read and mixed workload performance. High random IOPS capability ensures rapid response times for transactional systems, metadata-heavy applications, and distributed storage clusters where thousands of simultaneous read requests occur continuously.

Applications such as NoSQL databases, indexing engines, real-time search platforms, and web-scale application hosting can leverage the SSD’s ability to maintain predictable low latency under sustained pressure.

Reduced Application Latency

Latency consistency is critical in enterprise computing. The Kioxia CM7-R minimizes performance variability through sophisticated controller design and optimized firmware scheduling. This allows storage administrators to maintain service-level agreements and improve application responsiveness across cloud-native workloads.

High-Density Data Center Storage

With 30.72TB of usable flash storage in a single U.2 drive, the Kioxia SDF3080DAB01T provides exceptional storage density. Enterprises can deploy fewer drives to achieve desired capacity targets, simplifying storage architecture and reducing operational complexity.

High-capacity SSD deployment supports efficient server consolidation, allowing organizations to maximize available drive bays while improving compute-to-storage ratios. This is especially beneficial in dense 1U and 2U rack servers where physical space is limited.

Reduced Rack Footprint

By replacing multiple lower-capacity drives with fewer 30.72TB SSDs, data centers can significantly reduce rack occupancy and cable management overhead. Fewer drives also mean reduced cooling requirements and improved airflow efficiency.

Ideal for Tier-0 and Tier-1 Storage Pools

The CM7-R serves as an excellent foundation for premium storage tiers where both speed and capacity are essential. It can function as a high-speed cache tier, primary transactional storage layer, or dedicated application acceleration pool within hybrid storage environments.
