Crucial P3 Plus 4TB NVMe internal SSD

Capacity and Interface

The Crucial P3 Plus is a 4TB internal SSD built on the NVMe protocol over PCIe Gen 4 x4. It targets users who need a single high-capacity drive for laptops or desktops without managing multiple volumes. Buyers who require more storage than 4TB will need to add a second drive or choose a larger model. The M.2 form factor fits standard slots in modern systems.

Sustained Write Behaviour

Sequential write speed is rated at 4,100 MB/s and sequential read at 4,800 MB/s. The drive uses 3D NAND and is rated for 800 TBW of total endurance. Under continuous heavy writes the controller manages throughput to stay within thermal and wear limits. Workloads that exceed the rated write bandwidth or endurance budget will see reduced performance or lifespan.

Thermals Noise and Power

The manufacturer highlights a low noise level, which is inherent to the solid-state design with no moving parts. Power draw scales with the PCIe Gen 4 x4 interface activity and the 4TB NAND array. In typical mixed workloads the drive runs within standard M.2 thermal envelopes without active cooling. Extreme sustained loads may require motherboard heatsink support.
