A:Answer Space:
Samsung drives adhere to the IDEMA standard of advanced formatting, which will result in the drive appearing as less than the listed size. This is a common industry-wide standard.
The amount of space that appears to be "missing" is in fact used by the drive/card for storing firmware, metadata and spare blocks. Your operating system (Windows, Linux, etc.) will also affect the usable space -- different operating systems will use different amounts of space to store their metadata. Consequently, formatted space will always be less than unformatted space.
You can look IDEMA up online for more technical details about this standard, which is established by The International Disk Drive Equipment and Materials Association.
