16 GB micro SDHC 10 Class W/adapter QUESTION: Why does the micro SDHC card have less actual space than what is stated: ANSWER: The reason is between computer manufacturers and storage manufacturers. A computer says a kilobyte is 1024 bytes and a megabyte is 1024 kilobytes. One megabyte (actually 1 million bytes) is 1,048,576 (bytes). 32 GB multiplies 1024 (bytes) x 1024 (kilobytes) x 1024 (megabytes) x 32 (gigabytes) of information which equals 34,359,738,268 bytes. Computer hard drive and storage manufacturers define a GB in even numbers, as a billion bytes. With 16 GB storage medium you actually get 16 billion bytes. With 32 GB storage medium you actually get 32 billion bytes minus any programming on storage device.
