The Drive

The drive uses the M.2 2280 form factor, which makes it 22 mm wide and 80 mm long.


Like most M.2 NVMe SSDs, the HP EX950 connects to the host system over a PCI-Express 3.0 x4 interface.


On the PCB, you'll find the controller, four flash chips, and two DRAM chips.

Chip Component Analysis

The Silicon Motion SM2262 is an eight-channel flash controller with support for NVMe 1.3, TLC, and DDR3/DDR4 memory. Apparently, HP has customized it in some way, as evident by the HP logo and the different model number.


The four flash chips are Micron 64-layer 3D TLC NAND; they have been rebranded by HP, too. Each chip has a capacity of 512 GB.


Two Micron DDR3-1600 chips provide a total of 2 GB of fast DRAM storage for the controller to store the mapping tables.
