HP EX 950 SSD M.2 NVME | The FASTEST SSD i have Used 😝 3500 MB/S


The HP EX950 has Nanya or Micron 512 - 2TB DDR3. DRAM makes SSD work faster, but also more expensive.

The HP EX950 due to the low density of memory chips can run without further cooling systems. Some laptops or motherboards designed with thermal pads above and below the drive to enhance performance during heavy loads.

The HP EX950 has sequential write speed 2900 Mb/s, read speed 3500 Mbps. It run on Silicon Motion SM2262EN controller and M.2 3.0 x 4 interface standard. The NAND flash memory type is Micron TLC.
