Depending on manufacturer, and storage conditions, it can be up to about ten years. But the “three months” number is real: https://web.archive.org/web/20210502042514/http://www.dell.c...

That's a document from nine and a half years ago, and it states:

> It depends on the how much the flash has been used (P/E cycle used), type of flash, and storage temperature. In MLC and SLC, this can be as low as 3 months and best case can be more than 10 years. The retention is highly dependent on temperature and workload.

Are there any modern sources provide more accurate stats? "3 months to 10 years" is so vague as to be useless.

Consumer SSDs (unlike enterprise SSDs) must have a retention time of at least 1 year at the end of their life.

To achieve that target, when they are new they must have a retention time of a few years, but you should better not count on that.
