Interesting. I've only had one brand of SS/flash drive actually fail (ADATA UE700, and replacement). But most of mine seem to heat up very quickly, then soon throttle the speeds (probably to mitigate further heat or death). The T7 will be my first portable SSD for larger backups, and I hope it handles heat much better.

I am/was using mostly WD Passport HDDs for backups, which I disconnect and put in a safe. Shocked that this newest one has only 30 hours usage, very gentle handling (same as others), yet it's apparently failing. (So tired of worrying about tiny fragile spinning disks and mechanisms!) Will backup, and try deleting some files, hoping maybe it just hates being nearly full (about 70-80%). SMART data says it's healthy, but maybe would until it's too late.
