Micron 9400 12.5 TB NVMe SSD

This Micron 9400 internal solid-state drive provides 12.5 TB of storage in a 2.5 inch form factor. It connects through a PCI Express NVMe 4.0 x4 interface and is intended for consumer workloads. The drive delivers maximum sequential read and write speeds of 7000 MB/s. Random 4KB performance reaches 1600000 IOPS for reads and 300000 IOPS for writes.

PCI Express NVMe 4.0 x4 interface limits

The NVMe 4.0 x4 link caps sustained throughput at the drive’s rated 7000 MB/s in both directions. Real-world speeds depend on the host controller, queue depth and thermal conditions. The 15 mm z-height requires a 2.5 inch bay that accepts 15 mm drives. The U.3 connector is mechanically compatible with U.2 backplanes but electrical negotiation follows the NVMe specification.

12.5 TB capacity decides fit

At 12.5 TB the drive suits workloads that need high capacity in a single slot, such as large media libraries or local data caches. The 70080 TB total bytes written rating indicates the endurance budget for sustained write traffic. Buyers should verify that their system accepts a 15 mm 2.5 inch NVMe drive before purchase.

Questions about this item

Should I choose the 12.5 TB capacity or is there another version listed?

The product data shows only the 12.5 TB capacity for this Micron 9400 model.

What does the 7000 MB/s sequential read figure mean once the drive is installed in my system?

It is the maximum sequential read speed the controller can deliver over the PCIe 4.0 x4 link; real-world throughput will depend on workload, queue depth and system configuration.

The drive uses a PCIe NVMe 4.0 x4 interface — what does that cap in practice?

The x4 lane width and Gen 4 signalling limit the theoretical bandwidth to about 8 GB/s, so the 7000 MB/s ratings sit within that ceiling.
