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
