  Frequently Asked Questions :  
1. Why I bought 8GB USB, but the computer show it is about 7.4GB? 
  Because:
a Flash memory producers are using decimal arithmetic:
  1KB=1000Bit, 1MB = 1000KB, 1G = 1000MB
b Calculated, the operating system using binary arithmetic:
  1KB=1024Bit, 1MB = 1024KB, 1GB = 1024MB
c That is why there are some differences between display capacity and nominal capacity 
of flash  memory product. And different factories will produce different capacity USB
flash drives. So it is normal to has little capacity deviation!
4GB     = approximately 3.6GB-3.8GB
8GB     = approximately 7.4GB-7.6GB
16GB   = approximately 14GB-15GB
32GB   = approximately 28GB-30GB
64GB   = approximately 58GB-60GB
*Please note that: Our USB flash drive is the real capacity,you can use the H2text to text 
it.H2text is the most authoritative testing software in the world.

2. Why the USB write speed it so slow?
Our USB flash drives write speed is 5M/S-10M/S.
But the write speed will be unsteady according to different computer configuration and
your file size.

3. Why the device is not recognized?
Normally, when you connect USB drives to the computer, it will installs the driver
automatically. If your USB flash drive is not recognized, please turn off the firewall and
antivirus software of your computer and try again. If it still can not work,please contact
us, we will help you solve this problem.

  Tips for Usage :  
1. When you use your USB flash drive, it is better to copy your files to the computer
than operate your files in USB flash drive directly.
2. Please do not remove your USB flash drive when it is being used otherwise your data
may loss.

helps to extend its storage lifetime.

damaged easily.
