Capacity and Interface

The Crucial P3 Plus is a 4TB internal solid-state drive built in the M.2 2280 form factor. It connects through a PCI-Express 4.0 x4 interface using the NVMe protocol. Sequential reads reach up to 4800 MBps and writes up to 4100 MBps.

Suitability

This drive suits professionals, enthusiasts and gamers who want a large NVMe volume for fast system responsiveness and game loading. Systems limited to PCIe 3.0 will not achieve the quoted 4800 MBps read and 4100 MBps write figures.

Deciding Specification

The PCI-Express 4.0 x4 NVMe interface is the single specification that decides compatibility. Verify your motherboard provides an M.2 slot wired for PCIe 4.0 x4 to obtain the rated 4800 MBps read and 4100 MBps write performance.

Questions about this item

Does my motherboard need an M.2 2280 slot with PCIe 4.0 x4 support to install the CT4000P3PSSD8?

Yes, the drive uses the M.2 2280 form factor and connects via a PCIe 4.0 x4 NVMe interface, so the slot must provide that electrical link.

Will the P3 Plus 4TB work in a PCIe 3.0 M.2 slot if I keep my current board?

It will operate at PCIe 3.0 speeds, limiting sequential reads to the slot's lower bandwidth instead of the drive's 4800 MBps maximum.

How can I verify the SSD is delivering its rated 4800 MBps read and 4100 MBps write performance after installation?

Run a sequential benchmark such as CrystalDiskMark using a 1 GiB test file on the NVMe drive and compare the results to the 4800/4100 MBps figures.
