Why: Flash memory manufacturers use decimal arithmetic:1KB=1000Bit, 1MB=1000KB, 1G=1000MB calculated, OS uses binary arithmetic:1KB=1024Bit, 1MB=1024KB, 1GB=1024MB Which is why there are some differences between the display capacity and the rated capacity of the flash memory product. And different factories will produce USB flash drives with different capacities. 4gb=approx 3.6gb-3.8gb 8gb=approx 7.1gb-7.6gb 16GB=approx 14gb-15gb 32GB=approx 28gb-30gb 64gb=approx 58gb-60gb 128gb=approx 115gb-121gb 256GB=approx. 240gb-252gb Suggestions for use: 1.When you use the USB flash drive, it is better to copy the files to your computer rather than directly use the files in the USB flash drive. 2.Do not remove the USB flash drive when using, otherwise the data may be lost. 3.After using the USB flash drive, it is better to remove it as soon as possible. This will help extend the storage life. 4.Do not format the USB flash drive frequently.
