Data copying speed is slowing down
One of the most obvious signs is that the data transfer speed of the USB has decreased significantly compared to before. The reason may be due to the degradation of the internal flash memory or simply because the device is too old compared to current standards.
For example, USB 2.0 standard USBs only support a maximum speed of about 480 Mbps, while USB 3.2 Gen 1 can reach 5 Gbps, USB 3.2 Gen 2 reaches 10 Gbps and USB 3.2 Gen 2x2 up to 20 Gbps.
If you often have to wait too long to copy large files, especially videos or work data, upgrading to a new USB model can help save significant usage time.
Loose plug, intermittent connection
The fact that the USB continuously loses connection, especially when there is only a mild impact, may indicate that the plug or internal components have been damaged after a long period of use.
Users can check by plugging the USB into the computer and gently shaking it. If the operating system continuously displays connection and disconnect notifications, or a "USB Device Not Recognized" error appears, it is highly likely that the device has hardware problems.
However, before concluding that the USB is broken, you should try it on many different connection ports to rule out the possibility that the error originates from the computer's USB port.
Frequently faulty files or data loss
According to experts, the NAND Flash memory inside the USB only has a certain lifespan with a limited number of data writes and deletions. After a long period of use, memory cells may be degraded in quality, leading to data errors.
In addition to lifespan, physical damage, malware, or sudden removal of USBs while recording data can also cause file damage.
To limit this risk, users should always use the "Safely Remove Hardware" function before removing the USB from the computer to ensure the data writing process is complete.
Storage capacity no longer meets demand
USB capacity is also very diverse today, from a few GB to tens of terabytes. However, if you frequently fall into a state of full memory and have to continuously delete or move data to clear space, this is the time to think about upgrading.
Constantly writing and deleting data is not only inconvenient but also increases the wear-and-burn speed of flash memory. For users who regularly work with large-capacity documents, images or videos, experts recommend choosing USBs from 256GB or more, and prioritizing products with high data transfer speeds to meet long-term usage needs.
