The HP EX950 has Nanya or Micron 512 - 2TB DDR3. Dynamic Random-Access Memory in their controller help to increase I/O performance and endurance.

The HP EX950 due to the low density of memory chips may last with no further heat sinks. Some laptops or motherboards already has additional cooling below or above the drive for improving performance during heavy loads.

The EX950 512Gb has write speed 2900 Mb per second, read speed 3500 Mbps. It operate on Silicon Motion SM2262EN controller and M.2 3.0 x 4 interface standard. The memory type is Micron TLC.
