.What is the real capacity?

Flash memory vendors are using decimal arithmetic:1MB = 1000KB,1G = 1000MB

calculated, the operating system using binary arithmetic:1MB = 1024KB,1GB = 1024MB;

128MB= approximately 110MB-120MB
256MB = approximately 230MB-245MB
512MB = approximately 460MB-480MB
    1GB = approximately 800MB-999MB
    2GB = approximately 1.60GB-1.85GB

    4GB = approximately 3.6GB-3.8GB

    8GB = approximately 7.2GB-7.6GB

  16GB = approximately 14GB -15GB

  32GB = approximately 28GB -30G

64GB = approximately 58GB -60GB
