Micron 3400 Series 2TB NVMe drive

The Micron 3400 Series MTFDKBA2T0TFH-1BC1AA is a 2TB internal SSD built for consumer workloads. It uses the M.2 2280 form factor and connects through a PCI-Express 4.0 interface with NVMe 1.4. TLC memory components provide the storage medium for everyday computing and content creation.

Host-controlled thermal management and power draw

Host-controlled thermal management lets the system regulate drive temperature during normal operation. Power-loss protection secures data at rest while a power-loss signal prepares the controller for sudden shutdowns. Hardware-based AES 256-bit encryption runs without measurable impact on throughput or power consumption.

Sustained load behaviour

Dynamic write acceleration maintains write performance when workloads extend beyond short bursts. The drive is rated for 1200TB written and an MTTF of 2 million hours. TCG Opal 2.01 and TCG Pyrite 2.01 support enterprise-grade security during prolonged use. Micron Storage Executive tool monitors health and applies firmware updates.

Questions about this item

How do I install the M.2 2280 SSD and what step is often missed?

Insert the drive into the PCI-Express 4.0 slot at a 30-degree angle, secure it with the motherboard screw, then enable NVMe 1.4 in BIOS; the step most people skip is checking that the motherboard PCIe lane allocation supports full 4.0 x4 bandwidth.

What maintenance or replacement will the 2TB TLC drive need later?

The drive has a 1200 TBW endurance rating and 2 Million hour MTTF; no routine maintenance is required, but once the 1200 TBW limit is reached the NAND cells may no longer guarantee data retention and the drive should be replaced.

What limit appears first during sustained heavy writes on this PCI-Express 4.0 SSD?

Under continuous write loads the host-controlled thermal management will throttle performance to protect the controller; the dynamic write acceleration buffer can absorb bursts, but sustained writes beyond the SLC cache will hit the thermal throttle limit before the 5000 MBps sequential write ceiling.
