Who doesn't have an m.2 slot but the money to afford this?

The J(E)DEC industry standard for consumer drives requires a minimum of 1 year of data storage without cell refresh at ambient temperatures up to 35C and 99% NAND wear.

In reality, everything depends on the conscientiousness of the SSD manufacturer, but even Samsung slyly does not indicate anywhere the real data storage time, which it guarantees without updating the cells and at what acceptable temperature. There is no talk of the second and third echelons.

In the end, this is the problem of an adequate consumer. But these are the minority. The rest, only having lost data, begin to think about multiple backups of valuable data.

Unfortunately, there are no government-mandated storage standards in the world, which is now (gradually) leading to a completely wild and dangerous situation, especially with QLC and an even more terrible future of PLC.

Instead of going back to at least MLC, and preferably SLC thanks to 3D stacking of chips, manufacturers (and stupid consumers, and they are the majority) are chasing capacity and speed.

But first of all, we need reliability and long-term storage ...

For those thinking of using it for cold storage: gentle reminder that, unlike HDD, with SSD, if not powered up every once in a while, data starts getting corrupted (on some brands/models, as little as a month).
