6.4TB enterprise NVMe drive

The Micron 7400 MAX delivers 6.4TB of 3D TLC storage over a PCI-Express 4.0 link using NVMe 1.4. It targets data-centre workloads that demand high capacity and consistent low latency. The 7.00mm height fits standard U.2 or U.3 bays in modern servers.

Sustained write behaviour under load

Sequential write speed reaches 5400 MBps while random write IOPS hold at 363,000. Write latency stays at 15 µs even during extended operations. The drive operates reliably between 0°C and 70°C, so thermal throttling is less likely in densely packed chassis.

PCI-Express 4.0 bandwidth ceiling

The x4 lane interface caps theoretical throughput near the stated 6600 MBps read and 5400 MBps write maxima. NVMe 1.4 command-set features rely on host support for the same specification revision. Systems limited to PCI-Express 3.0 will not reach the published sequential figures.

Questions about this item

How much power does the 6.4TB Micron 7400 MAX draw under sustained PCIe 4.0 workloads?

The drive operates within a 0°C to 70°C range, and its 7.00mm height fits standard enterprise airflow designs for continuous operation.

What slot and protocol does the MTFDKCB6T4TFC-1AZ1ZABYY require on the host system?

It needs a PCI-Express 4.0 slot with NVMe v1.4 support to deliver up to 6600 MBps read and 5400 MBps write speeds.

Will this 7400 MAX SSD work in a server that only has PCIe 3.0 backplanes?

Yes, the NVMe v1.4 interface is backward compatible with PCIe 3.0, though sequential speeds will be limited to the older bus.
