According to PCWorld , the lifespan of data stored on a USB flash drive depends on many factors. Under ideal conditions, data can be preserved on a high-quality USB flash drive for at least 10 years, or even longer. But this is only true if the drive is used and stored properly.
Many people hesitate to back up data to a USB flash drive.
USB flash drives store data using NAND flash memory technology, in which data is represented as binary values (0s and 1s) in memory cells. Electrons in this memory can “leak” over time, making data difficult to read and at risk of being lost.
USB flash drives are not an option for long-term storage
While USB flash drives are convenient for quick storage and transfer of data, they are not the best choice for long-term storage. This is why other media such as magnetic tapes or optical discs are often recommended for this purpose.
There are a number of factors that affect the lifespan of data on a USB flash drive, including the quality of the NAND flash memory and the overall quality of the drive. Cheaper USB flash drives tend to have shorter lifespans. Additionally, the number of write cycles—that is, how often data can be written and erased—also affects the ability to retain data. As the number of write cycles increases, so does the risk of data degradation.
Additionally, environmental conditions such as high temperatures, high humidity, or dust can also reduce data longevity. If a USB flash drive is exposed to high temperatures for long periods of time, electrons can “leak” more quickly, leading to data loss.
In short, USB flash drives are not ideal for long-term storage of important data. Regular backups to other media, such as external drives, are necessary. If you want to protect your data for a long time, consider using magnetic tape or optical media. In particular, it is not advisable to store important data in only one place and on one medium. USB flash drives are generally best for quick file transfers or creating bootable media.
