4TB NVMe storage for consumer workloads

This Crucial P3 Plus drive delivers four terabytes of capacity in the M.2 2280 form factor. It uses Micron 3D NAND and a PCI-Express 4.0 x4 NVMe interface for internal storage upgrades. The drive targets consumer desktops and laptops that need high-capacity solid-state performance.

Backward compatibility with Gen3 systems

The PCIe 4.0 interface operates at full speed on supporting platforms and falls back to Gen3 on older motherboards. This allows the same drive to serve new builds and upgrade older machines without a separate purchase. No bundled software or accessories are included with the bare drive.

PCIe 4.0 x4 lane limit and sequential throughput

The x4 link caps maximum sequential transfer at the interface ceiling of PCIe 4.0. Rated speeds reach up to 4800 MBps read and 4100 MBps write, so sustained workloads cannot exceed that bandwidth. Real-world throughput also depends on host controller implementation and thermal conditions.

Questions about this item

Will this M.2 2280 drive fit in a laptop slot that only supports PCIe 3.0?

Yes, the drive is backward compatible with PCIe 3.0 slots, though sequential speeds will be limited to the Gen3 maximum.

Does the 4TB capacity require a heatsink for sustained writes?

The drive uses Micron 3D NAND and operates within standard M.2 thermal limits; a motherboard heatsink is recommended for heavy workloads but not mandatory.

What real-world benefit does the 4800 MBps read speed give over a Gen3 drive?

The manufacturer states up to 43 percent faster performance than the fastest Gen3 NVMe SSDs, cutting load times for large games and video projects.
