Mission-critical data?
There can be no compromises.

A cavalier approach to moving, ingesting, analyzing and storing your customers’ precious data resource is not an option. Data must be treated like the valuable commodity that it is — otherwise competitors can gain advantage. The Micron® 9400 NVMe SSD is the answer when data center performance is critical. Micron’s latest Gen4 NVMe storage solution delivers uncompromising balanced performance, consistent responsiveness and up to massive 30TB+ capacities needed to handle torrents of valuable data.

Data center performance without compromise

Optimized for a wide variety of performance-critical workloads — caching, content delivery, block and object stores, and training/caching for AI — the Micron 9400 SSD can consistently read and write at 7GB per second for sequential data. In fact, the 9400 SSD sequential writes speed leads the industry by 66%1. At the same time, its random read and write performance of up to 1.6M IOPS is also the industry fastest1. No other product in its class can deliver mixed-use optimal performance on both sequential/random and both read/write like this.

Deliver rapid and consistent responsiveness

The Micron 9400 SSD is optimized for mission-critical, strenuous data center workloads that require strong mixed performance and massive capacity. It also delivers results for massive high-speed OLTP. Workloads range from content delivery networks (caching) to AI/ML and performance-focused databases that thrive on extreme IOPS and low, , consistent 6x9s (six-nines)1 read latency. The Micron 9400 SSD produces mixed workload performance that is up to 2.3x greater2 than the other leading brands while also improving 6x9s read latency by as much as 3.2x1. For these applications, fast ingest alone isn’t enough: responding in microseconds delivers a competitive advantage.

Big capacities for big data

The Micron 9400 SSD brings the storage density that data centers and workloads demand. It offers more than 30TB3 maximum capacity, twice the maximum capacity of our prior generation SSD. Increased capacity per SSD simplifies storage of your data assets by using half as many servers to help reclaim valuable rack space (and reduce maintenance costs).
