The drive uses the M.2 2280 form factor, which means it is 22 mm wide and 80 mm long.
Like most M.2 NVMe SSDs, the Crucial P1 uses a PCI-Express 3.0 x4 interface.
You will find the SSD controller and two flash chips on the PCB. A single DDR3 DRAM chip is also present to provide the SSD controller with operating memory for mapping tables. The other side of the PCB is empty.
The Silicon Motion SM2263ENG is a new controller with support for QLC NAND flash.
The two flash chips are Micron's own 64-layer QLC NAND. Each chip has a capacity of 512 GB.
A Micron 1 GB DDR3 chip provides fast DRAM storage for the controller to store the mapping tables in.
