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.
