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.
