Technically SSDs will forget numbers too if left disconnected from power and in a hot room
That's like saying HDDs will forget numbers if you store them next to a powerful magnet. Most SSDs have an operating range up to 70°C, so that hot room would have to be more like an oven.
I'm guessing the original commenter lives in an uninsulated tin shack in the Arizona desert.
That is why I Ilisted the unpowered/ unplugged. there are white papers on ssd data loss when it is disconnected from mobo and stored. The lack of trickle power allows decay in the mem cells simce they are just packed charges, and heat accelerates that loss. They said in as little as a week in a hot room it will have started bit rot. And in some cases a few months in a hot space (say 40 degrees in summer heat we have) and data is gone.
Applying power by itself doesn't keep SSDs from degrading like DRAM though. It's up to the manufacturer to design scrubbing into the controller to correct errors on infrequently accessed data before it's too far gone.
No, HDDs will forget numbers too if left too long without power. Especially the notebook models. The magnetizion wears off.
Not the whitepaper research paper I was trying to reference but if you read just below the temp chart image is explains similar info about how quick SSD (unpowered) data loss is based on ambient heat. HDD while also succeptible to data loss is a better archive medium than SSD https://www.anandtech.com/show/9248/the-truth-about-ssd-data-retention
The data was for a worn out SSD 9 years ago. Drive data retention is way higher than that nowadays.
Like I said that is just one link, there was a recent whitepaper about it, just lost my link.
Or drive a nail into them. Granted, most of these devices will stop functioning if you do that...
