Micron 7400 PRO 7.68TB U.3 NVMe drive

This Micron 7400 PRO enterprise SSD delivers 7.68TB of 3D TLC storage in a 2.5-inch U.3 form factor. It connects through a PCI-Express 4.0 interface using NVMe v1.4 protocol. The drive targets data-centre workloads that demand high-capacity read-intensive performance with consistent low latency.

Verify U.3 backplane and PCIe 4.0 slot availability

Before ordering, confirm the server or storage array provides a U.3 backplane with PCI-Express 4.0 electrical support. The 7.00mm z-height matches standard 2.5-inch bays, but the connector keying requires a compatible U.3 or tri-mode slot. Ensure the platform BIOS and drive firmware are current for NVMe v1.4 feature enablement.

Sustained throughput with 15 µs write latency

Under continuous load the drive maintains up to 5400 MBps sequential write and 190000 IOPS random write while keeping write latency at 15 µs. Sequential read reaches 6600 MBps and random read hits 1000000 IOPS with 75 µs read latency. The 0°C to 70°C operating range supports steady-state performance inside dense chassis without thermal throttling.

Questions about this item

Does the 2.5" U.3 7.68TB drive ship with any mounting hardware or cables?

The drive is supplied as a bare 2.5" U.3 unit; mounting brackets, screws and U.3 or PCIe cabling must be sourced separately.

Why choose the 7.68TB capacity over other 7400 PRO sizes?

The 7.68TB model provides the highest density in the 7400 PRO line, maximising storage per 2.5" bay while keeping the same 6600 MBps read and 5400 MBps write ceilings.

What does the 6600 MBps sequential read figure mean for a live server workload?

It represents the peak throughput the controller can sustain on large-block reads; real-world speed will depend on queue depth, CPU overhead and thermal limits inside the chassis.
