What to do if my USB flash drive malfunctions

1) My storage device does not appear in the file explorer:

  • Check that the USB drivers are up to date on your PC
  • Test the storage device on another USB port on the computer
  • Test the storage device on another computer
  • If you are using a USB HUB, we recommend that you connect it to an external 5V USB power supply as the HUB uses some of the power for its own operation.

If the problem is not with the computer, please return the USB flash drive to your dealer with proof of purchase so that it can be taken care of under warranty.

2) Reading or writing speed seems slow:

  • Make sure that the storage device is connected to a fast USB port that matches the USB standard* of the storage device. It is recommended not to use USB 2.0 ports for fast data transfers.
  • If you are using a HUB Check that the HUB and the computer's USB port are compatible with the USB* standard of the storage device

*USB standards:

  1. USB 2.0: Actual speed up to 40 MB/s
  2. USB 3.2 Gen1: Actual speed up to 500 MB/s
  3. USB 3.2 Gen2: Real speed up to 1000 MB/s = 1 GB/s
  4. USB 3.2 Gen2x2 : Real speed up to 2000 MB/s = 2 GB/s
  5. USB 4.0: Real speed up to 4000 MB/s = 4 GB/s

Check your computer's documentation to know the characteristics of your USB ports.

IMPORTANT : BUFFER MEMORY

If you use the storage device intensively with a large amount of data (several GB), you may saturate the memory buffers of the storage device, which will cause the storage device to slow down momentarily. To return to normal, leave the storage device plugged in for a few moments without writing data to it.
