From the above linked articale

"... Your SSD data isn't as permanent as you think Even the cheapest SSDs, say those with QLC NAND, can safely store data for about a year of being completely unpowered. More expensive TLC NAND can retain data for up to 3 years, while MLC and SLC NAND are good for 5 years and 10 years of unpowered storage, respectively. ..."

RE "...QLC NAND, can safely store data for about a year of being completely unpowered...."

QLC Nand only reliably stores data for only a year .

This would be within the warranty period for some products.

This information should be more clearly shown to product purchasers.
