Product overview

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.

Frequently asked questions

What form factor does the SDF2B84DAB91T use?

The KIOXIA SDF2B84DAB91T utilizes the E3.S form factor (112.75x76x7.5mm), optimized for high-density OCP and hyperscale server trays. This compact design supports up to 10+ drives per 1U while maintaining superior airflow compared to traditional U.2 drives.

What are the peak performance specifications?

Sequential reads reach 6,800 MB/s, writes 3,800 MB/s, with random 4K reads up to 1,000,000 IOPS and writes up to 230,000 IOPS over PCIe 5.0 x4 NVMe. These metrics excel in read-heavy virtualization, databases, and analytics workloads.

Is this SSD suitable for read-intensive workloads?

Yes, rated at 1 DWPD with 3,600 TBW endurance over 5 years, it's optimized for read-intensive enterprise/datacenter applications like caching, content delivery, and OLAP databases where reads significantly outnumber writes.

What interface and protocol does it support?

PCIe Gen5 x4 with NVMe 2.0 protocol, backward compatible with Gen4/Gen3 systems at reduced speeds. Supports advanced queueing and multi-path I/O for optimal performance in modern server platforms.

What is the reliability rating?

Features 2 million hours MTBF, power loss protection, and end-to-end data protection. Designed for 24x7 operation in dense rack environments with active thermal throttling prevention.

What NAND technology is used?

KIOXIA 3D BiCS FLASH Triple-Level Cell (TLC) NAND provides high capacity density, balanced endurance, and power efficiency ideal for large-scale read-intensive deployments.
