The KIOXIA SDF2B84DAB91T from the CD7-R series is a 3.84TB read-intensive NVMe SSD engineered for high-density datacenter deployments. Featuring PCIe 5.0 x4 interface and E3.S form factor, it delivers sequential reads up to 6,800 MB/s, writes up to 3,800 MB/s, random reads up to 1,000,000 IOPS, and random writes up to 230,000 IOPS. Built with 3D BiCS FLASH TLC NAND, it offers 3,600 TBW endurance and 2 million hours MTBF for 24/7 mission-critical operations. The compact E3.S (Enterprise and Data Center Standard Form Factor) design optimizes rack space in Open Compute Project (OCP) and hyperscale environments, enabling higher storage density without compromising airflow or performance. Power-efficient operation supports sustainable datacenter scaling while maintaining low latency for virtualization, databases, and analytics workloads. Ideal for cloud providers, service operators, and large-scale enterprises requiring consistent read performance across massive datasets. Compatibility with NVMe 2.0 protocols ensures seamless integration into modern server platforms supporting PCIe Gen5 backplanes. Advanced thermal management prevents throttling under sustained loads, while enterprise-grade reliability features like end-to-end data protection safeguard critical data integrity.
