A closer look at “Why You Should Back Up Data on Your Older Thumb Drives Before It's Too Late”, exactly as the source publishes it. Flash drives are handy for moving files, but they aren't built for long-term storage. Over time, the NAND flash memory inside USB sticks can lose charge, leading to silent data corruption or complete failure. This is especially true for drives that are several years old or have been used heavily.
Unlike external hard drives or cloud storage, thumb drives have no moving parts to warn you before they die—they just stop working. That's why experts recommend backing up anything saved on an older thumb drive to at least one other location, such as a cloud service or an external SSD. The risk grows as drives age, and many people don't realize their files are at risk until it's too late. For the complete material, the listing points back to the source inside the network.
