Micron

Micron 2TB 3400 M.2 2280 NVMe PCIe 4.0 x4 internal SSD

SKU CH-QQR2-7X9KM

A 2 TB M.2 2280 NVMe drive delivering up to 6600 MB/s reads and 5000 MB/s writes with 2.0 million hours MTTF

  • Device TypeInternal / External Solid State Drive (SSD)
  • Up to 6600 MB/s sequential read speeds via PCIe 4.0 x4 interface
  • Up to 5000 MB/s sequential write speeds for fast data transfers
  • 720K random read IOPS for responsive application loading
  • 700K random write IOPS for smooth multitasking performance
  • 0 million hours MTTF rating indicates long-term drive reliability

Capacity and interface

This Micron 3400 drive delivers 2TB of storage over a PCIe 4.0 x4 link in the M.2 2280 form factor. It is built for laptops, desktops and ultrabooks that need fast NVMe performance.

Motherboard slot and protocol check

Verify that your system has an M.2 2280 slot wired for PCIe 4.0 or 3.0. The drive will operate at reduced speed in a PCIe 3.0 slot, so confirm the slot generation to match your performance target.

Upgrade path and value

It replaces a slower PCIe 3.0 NVMe drive or a smaller capacity PCIe 4.0 module. The jump is worthwhile when workloads demand sequential reads up to 6600 MB/s, writes up to 5000 MB/s, or random IOPS of 720K read and 700K write with a 2.0 million hour MTTF rating.

Highlights

  • Up to 6600 MB/s sequential read speeds via PCIe 4.0 x4 interface
  • Up to 5000 MB/s sequential write speeds for fast data transfers
  • 720K random read IOPS for responsive application loading
  • 700K random write IOPS for smooth multitasking performance
  • 0 million hours MTTF rating indicates long-term drive reliability

Questions about this item

Does the Micron 3400 2TB M.2 2280 NVMe drive ship with a heatsink or mounting screw, or must they be purchased separately?

The drive is supplied as a bare M.2 2280 module. A motherboard standoff screw and any heatsink required by the laptop or desktop chassis must be sourced separately.

How do I decide between this PCIe 4.0 x4 model and a PCIe 3.0 alternative for the same capacity?

Choose the PCIe 4.0 x4 version when the platform supports it to reach 6600 MB/s sequential read and 720K IOPS random read; a PCIe 3.0 system will limit the drive to roughly half those throughput figures.

What do the 6600 MB/s sequential read and 720K IOPS random read figures mean once the SSD is installed in a real machine?

They represent the peak throughput and random access capability the controller can deliver on a PCIe 4.0 x4 link; actual sustained speeds depend on workload, thermal limits and the host system's implementation.
