If M.2 SSD then perfect cooling becomes an absolute must.
I ran into that, purchasing a laptop system from a configurator that forgot to install the tiny thermal pad under each M.2 SSD.
System broke down with motherboard failure, not knowing what was the cuplrit.
I complained, got a new motherboard under warranty, with thermal pads supplied as manufacturer designed.

Applied these pads while retrofitting my M.2 SSDs
System worked, but still bigger transfers somehow took their toll...

Only using HWinfo while doing bigger transfers showed the traces of death.
Short transfer bursts were withstood well. >1GB/s over more than 1 min the writing SSDs went over +75°C ,
then rates went belly up, then corruption because of emergency braking.

Reading the tiny SSD sticker:
3,3V 3A(!) means 10W of consumption and these 10W got to be dissipated well.

In the end I had to purchase a full set of thermal pad blanks of all thicknesses from 0,5 to 4mm,
then pad each and every accessible SSD area to motherboard, top bracket, even plastic parts.
Then 3,5/7Gb/s were steady, temperatures went from +45°C to +51°C, then +65°C and stayed there.

A hint: once such SSD crosses a certain thermal point of no return
(I guess around +70°C) then temperature stays there almost forever, even if transfer is stopped !

Thermal padding, and padding, and padding...
