Why is that the USB flash drive actual storage capacity slightly less than the product specification?

All storage product will display a lower than stated memory capacity when they are viewed on a computer. The reason for this discrepancy is the way in which manufacturers calculate a megabyte of memory.

32GB = 32,000,000,000 Bytes

1024Byte = 1K

32,000,000,000/1024 = 31,250,000 KB

1024KB= 1MB

31,250,000/1024 =30,517.57 MB

1024MB= 1GB

30,517.57 /1024 =29.8 GB

Therefore, the capacity of USB flash drive x 0.93 =Windows shown capacity.

 

 4GB      = approximately 3.5GB-3.8GB

8GB      = approximately 6.9GB-7.3GB

16GB    = approximately 14GB-15GB

32GB    = approximately 28GB-30GB

64GB    = approximately 58GB-60GB

128GB    = approximately 110GB-120GB

Note: the operating systems use binary arithmetic to calculate, that is: 1MB = 1024KB,1GB = 1024MB,

but our pendrive vendors use decimal arithmetic, that is 1MB = 1000KB,1G = 1000MB. so there are some differences between display capacity and normnal capacity of our usb flash drive.
