My bad - I should've looked up the model rather than assume you were talking about a naked NVMe drive - but to put my comment another way, I think we should all be treating modern SSDs as devices that need proper cooling, so next time you buy a portable drive, consider either putting one together by buying a metal enclosure (with cooling fins if possible), and put an SSD in it, or else try to find a pre-packaged drive with a metal case.
