The Crucial P1 has DDR3 / DDR4. Dynamic random-access memory (DRAM) makes storage work faster, but more expensive.

The Crucial P1 due to the low density of memory chips may last without extra heat sinks. Some laptops or motherboards from the factory has thermal pads above or below the storage to enhance productivity during times of high loads.

The Crucial P1 512Gb has maximum write speed 1750 Mb per second, read speed 2000 Mb per second. It run on Silicon Motion SM2263 controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The NAND memory type is Micron 3D QLC.
