When is it worth replacing a memory stick?
It is worth replacing the flash drive when it starts to show signs of unstable operation, its speed deviates significantly from its original parameters, there are problems with writing data or the operating system suggests that formatting is necessary. Also when memory errors are detected or confidence in the media is lost, as continued use may lead to irreversible data loss.
Signals indicating that a memory stick is worn out
Every memory stick has a limited technological life due to the nature of NAND flash memory. The most important limitation is programming and erasing cycles (P/E cycles). For typical media with MLC or TLC cells, this value ranges from a few thousand to tens of thousands of cycles. Once these are exceeded, data may be written erroneously and the media controller may start to mark more and more sectors as unusable. Symptoms of wear and tear are problems copying files, extended write times or sudden interruptions of operations , sometimes ending with an I/O error message. A common symptom is also that data has seemingly been saved, but when the flash drive is reconnected, the files disappear or have zero size. In some cases, the operating system reports that the flash drive needs to be formatted even when it was working correctly before. This could indicate a corrupted file system structure or a problem with the flash memory. If this situation occurs repeatedly, the media is no longer reliable.
Technical and usage criteria
Replacement of the flash drive is also advisable when its capacity and speed no longer meet the current needs of the user. Older models, operating in the USB 2.0 standard, offer very low read and write speeds compared to newer USB 3.2 Gen 1 or Gen 2 designs. This difference can be felt especially when transferring large multimedia files, ISO images or databases. Another case where replacement may be warranted is wear and tear mechanical, e.g. a loose USB connector, cracked Enclosures or scratches that can cause poor contacts and unstable operation. Such a flash drive can damage a computer's USB port or lead to accidental disconnection during data transfer. There is also the issue of data security. If the flash drive has been used for many years, in different computers and environments, there is a risk that it could have been infected with malware or has hidden system partitions. Even after formatting, some of these risks may remain, especially on older models with simple firmware. Any instance where a flash drive raises suspicions about its stability or data integrity should be a signal to replace it. The cost of buying a new, faster and more secure media is negligible compared to the potential loss of important data.
