why are USB flash drive "GB" so small?

Discussion in 'Storage' started by George Orwell, May 27, 2010.

  1. I got a USB flash drive of 8 GB, and it has just a pinch
    over 8 x 10^9 bytes. I know magnetic disk GB are so,
    but since the flash is solid state, I would expect that
    it goes in powers of 2: 1024^3.
    So where is the missing 7% of storage?

    Repeat after me: Storage sizes use SI prefixes.

    It has allways been that way. There is absolutely no
    storage missing from your device.

    Incidentlially this is not only legal, but usually
    required by law.

  4. Storage capacities are quoted in base 10, not base 2, as per the
    I have never learnt about this until I wrongly answered a question
    in a test. :)

    Nope, its just the difference between binary and decimal GBs.
    There is no point in binary with a hard drive or flash drives.
    The 1.44MB floppy is in fact a weird binary decimal hybrid.
