It seems the key to longevity is heat dissipation. If you have an SSD, or m.2 NVMe drive, it needs a heat sink or metal case or both. If all you are doing is saving Word files and other office documents, any of them is fine, but if you work with audio, video, or hundreds of large still images, heat dissipation becomes an issue.
Right! I keep an eye on temperature, and if a drive starts going much over 100° F, I stop the copying for a while. Even with external HDDs in a "fanned" enclosure, the temperature will keep rising while it's working.
