I don't understand this. Most laptops will have internal / ssd temperatures over 50C, and yet data usually lasts for years?
>>"client class SSD must maintain its data integrity at the defined BER for only 500 hours at 52°C (less than 21 days) or 96 hours at 66°C (only four days)."
Those are powered on when the laptop is on.
Right, but through which mechanism does that maKe a difference? Does controller periodically rewrite all contents? In other words how, does being powered-on increase retention of static data?
Yes, it does precisely that.
Also all of these are minimum requirements. They don't actually imply much, except about the state of technology when the statement was written. Flash has been improving very quickly on all axes.
And yet there are still people who will post about the good old days and the evils of MLC, as if current SSDs were not demonstrably better in every way.
