The Samsung 980 has HMB. This means that the SSD uses the system's random-access memory for its own operations. Dynamic random-access memory (DRAM) makes SSD work faster, but also more expensive.

The Samsung 980 2Tb due to the high density of memory chips you need to install of additional heat sink. This reduce temperature of the controller and memory. Some laptops or motherboards designed with additional cooling below and above the SSD for improving performance during times of heavy loads.

The Samsung 980 has write speed 3000 Mb/s, sequential read speed 3500 Mb per second. SSD operate on Samsung Pablo controller and M.2 3.0 x 4 interface standard. The memory type is Samsung TLC.
