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!

64MB   = approximately 58MB-60MB

128MB  = approximately 110MB-120MB

256MB  = approximately 235MB-245MB

4GB     = approximately 3.6GB-3.8GB

8GB     = approximately 7.1GB-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 H2textw to test  it.

H2textw 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.
