P3 4TB NVMe M.2 drive

The Crucial P3 4TB is an internal solid state drive built for consumer desktops and laptops. It uses an M.2 2280 form factor with a PCIe 3.0 x4 interface and Micron 3D NAND. Sequential reads reach up to 3500 MBps and writes up to 3000 MBps. Random performance hits 650000 read IOPS and 700000 write IOPS.

Gen3 upgrade from older NVMe

This drive replaces an earlier generation NVMe SSD and delivers up to 45% better performance. The jump is worth it when your current drive limits game loads, app launches or large file transfers. It adds 4000 GB of capacity without changing the motherboard slot.

Suits high-capacity Gen3 builds

Builders who need maximum space on a PCIe 3.0 platform will benefit from the 4TB density and steady speeds. Systems limited to PCIe 3.0 lanes see the full 3500 MBps potential. Users with PCIe 4.0 or 5.0 slots should consider faster drives to match their platform.

Questions about this item

Does the M.2 2280 form factor fit a standard motherboard slot?

Yes, the M.2 2280 form factor matches the common 80mm motherboard slot used for NVMe drives.

What is the correct way to secure the drive after inserting it at an angle?

Press the drive down flat and fasten the single retention screw into the motherboard standoff; skipping the screw lets the drive lift and lose contact.

How can I check the health of the 3D NAND over time?

Use the manufacturer's free monitoring tool to track SMART attributes such as percentage used and total bytes written.
