The HP EX900 is DRAMless drive or information about it is not known. Dynamic random-access memory (DRAM) in their controller help to improve endurance and input/output performance.

The HP EX900 due to the low density of memory chips may work with no additional cooling systems. Some motherboards or laptops already has additional cooling above and below the storage to improve productivity during times of high loads.

The HP EX900 1Tb has sequential write speed 1500 Mb per second, sequential read speed 2100 Mb per second. It run on Silicon Motion SM2263XT controller and M.2 3.0 x 4 interface standard. The NAND flash memory type is Micron TLC.
