1.Why I bought 8GB USB, but the computer show it is about 7.4GB?
·Flash memory producers are using decimal arithmetic:
1KB=1000Bit, 1MB = 1000KB, 1G = 1000MB
Calculated, the operating system using binary arithmetic:
1KB=1024Bit, 1MB = 1024KB, 1GB = 1024MB
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! So it is normal to has little capacity deviation! 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
Note: 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 and read 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.
