Capacity and form factor

The Crucial MTFDKCB6T4TFS-1BC1ZABYYR is a 6400 GB internal SSD built on Micron 176-layer NAND. It uses a 2.5 inch U.3 form factor with a PCIe 4.0 x4 NVMe interface for data centre deployment.

Enterprise mixed-use fit

This drive suits operators who need consistent sub-2ms QoS latency for boot, cache or main data storage in hyperscale or cloud infrastructure. Builders limited to M.2 slots or consumer desktop platforms should look at other form factors.

U.3 PCIe 4.0 x4 interface

The U.3 connector carrying PCIe 4.0 x4 NVMe is the single specification that decides compatibility; the system backplane must provide a U.3 bay with four PCIe 4.0 lanes for the drive to operate.

Questions about this item

What interface and form factor does the MTFDKCB6T4TFS-1BC1ZABYYR need on the host system?

The drive requires a U.3 PCIe 4.0 x4 slot in a 2.5-inch bay and uses the NVMe protocol.

Can the 7450 series SSD share a backplane with older PCIe 3.0 drives?

Yes, the PCIe 4.0 x4 interface is backward compatible so the SSD will operate at PCIe 3.0 speeds on an older backplane.

How can I verify the 176-layer NAND SSD is delivering its rated performance after installation?

Run an NVMe health tool to confirm the drive reports a PCIe 4.0 x4 link and check that latency remains consistently low under load.
