I'm testing how long SDD drives hold data without being plugged in. First part of the test is complete. 11 months for a Samsung T7 was OK. Next test is due early 2024. I have enough Samsung drives to go out for a few years of tests. I had heard they lose data if not plugged in periodically. The 'how often' part is up in the air. I've tested SD cards and they hold data pretty good. Also testing thumb drives, going out to 14 years...if I live that long.
Here are some SD card tests.

Will update thread as SDD drives are tested.
