The Micron 7400 SSD: SSD storage for demanding data centers



Data center workloads are constantly changing. In just a few short years, we have seen Artificial Intelligence (AI) rapidly move from research topics to integration into high-value data center workloads, with 5x the growth of projects from IA planned over the past two years.1

We have seen a heterogeneous computational scale used on a larger class of workloads. The IEEE noted in a recent article that “… heterogeneous computer architectures have been powering the world’s best supercomputers for many years and are now finding wider adoption in industry.2

Capacity per SSD continues to grow. Forward Insights noted that the average capacity of enterprise PCIe SSDs is expected to increase by over 70% over the next five years to 6,403 GB (2020 to 2025).3

In the same report, they also predicted that Flash Optimized Enterprise and Data Center SSD (EDSFF) E1 and E3 form factors will become an important part of the overall enterprise SSD form factors. (around 16% by 2025). While the demand for conventional form factors, such as M.2 and U.2, decreases in the same time frame, they still make up the majority of this SSD mix. This means that data center architects will need flexibility during the transition period from M.2 and U.2 form factors to EDSFF.

The smart advantage grows4, businesses capturing and analyzing data closer to the origin, while leveraging the benefits of cloud architectures5 including efficiency, cost reduction, flexibility, mobility and many more. These trends require flexible SSDs that can scale from edge to cloud.

With these advances, we still face challenges. For example, security is a priority for businesses. Data breaches in the first half of 2021 exposed 18.8 billion records.6Securing infrastructure from the edge to the cloud throughout the product lifecycle requires a new, simple, scalable, and cost-effective approach.

To meet the growing demands of today and the demands of tomorrow, storage must evolve. To thrive in these harsh conditions, you need three things: flexibility, performance, and security of storage solutions.

To help answer all three, we built the Micron® 7400 SSD with NVM Express â„¢ (NVMe â„¢). It is state-of-the-art storage that meets the demands of today’s and tomorrow’s servers with performance to match the workload and enhanced data security.

Flexibility to adapt to your designs

Micron 7400 SSD Offers World’s Largest SSD Portfolio7 for the data center. With U.3, M.2 and E1.S form factors, it is designed to meet changing energy and thermal needs. It offers a wide capacity range from 400GB to 7.68TB, supporting booting through high capacity storage applications. It’s the only one8 PCIe Gen4 U.3 form factor with 7mm and 15mm z heights. And this is the only one8 PCIe Gen4 M.2 22 x 80mm with power failure protection specially designed for server startup.

Scalable PCIe Gen4 performance

The Micron 7400 SSD is native PCIe Gen4 with PCIe Gen3 backward compatibility, so it can be used in PCIe Gen3 and PCIe Gen4 servers. The Micron 7400 SSD uses this backward and forward compatibility to ease your transition to Gen4. All Micron 7400 SSDs can run on Gen4 and Gen3 platforms, making sourcing and support easy.

The Micron 7400 delivers the performance and scalability you need:

2X The throughput of our previous generation data center SSD with NVMe (Micron 7300 SSD)
128 NVMe namespaces to maximize configurability
Gen4 Native PCIe with full PCIe Gen3 backward compatibility for an easier data center transition

Security9 for your most precious possessions

The Micron 7400 SSD is at the forefront of security, leveraging Micron’s security expertise to deliver a comprehensive set of features to help ensure data security, all with hardware-based performance.

Material security island
Dedicated security processing hardware with physical isolation provides an additional level of protection for key management.
Signed firmware binaries
Firmware update images are signed by Micron and verified by the Micron 7400 SSD to ensure that only Micron approved firmware is loaded.
Cryptographic erasure / disinfection
These ensure that the data on the SSD is not compromised. The data is unreadable by almost all currently known decryption technology data.
Secure namespaces
TCG Opal version 2.0 defines a standard for locking a namespace and LBA ranges within a namespace. Specification can be downloaded here.

Micron’s first SSD with OCP support

The Open Compute Project (OCP) has developed and published specifications that have built a thriving and standardized ecosystem. This ecosystem helps reduce the complexity of deployment and accelerate the time to market of the latest technologies, from the cloud to the distributed edge.

Micron has supported industry standards like this for decades and continues to support them as the foundation for rapid innovation around the world. Micron 7400 SSD is Micron’s first SSD designed for select OCP deploymentsten and is available in EDSFF form factors.


With our release of the Micron 7400 SSD, we bring all the benefits of our NAND leadership, controller design, DRAM expertise, global customer labs, world-class supply chain, and manufacturing organizations into the development of our data center SSDs.

Building on Micron’s history of innovation and technological leadership, our version of the Micron 7400 SSD delivers the industry-leading flexibility, performance and security to meet the needs of ever-changing data center workloads.
