M.2 SSD drives with heatsink

M.2 heatsink

— the presence of a heatsink in an M.2 form factor drive (see the relevant paragraph).

The heatsink is usually a metal plate attached to the drive board. It improves heat dissipation, which is especially important at high loads associated with large amounts of information. M.2 drives with a heatsink are designed primarily for high-performance systems, in particular gaming.

Also note that M.2 radiators are found as equipment for motherboards, so if the drive itself does not have this function, you can pick up a motherboard with a radiator for it.
