    Most phone manufacturers use the 1000 MB to 1 GB standard when selling phones. Hard drive manufacturers still use 1024 MB to 1 GB. Although the Institute of Electrical and Electronics Engineers adopted the 1000 MB to 1 GB standard in the year 2000 so the phone people are correct.

    Actually I think you'll find all storage devices quote their capacity in decimal (certainly my computer hard drives do this as well as my phone). Unfortunately any file explorer I've met shows file sizes in binary, so using decimal for the device means that storage devices look larger than they really are (this is why your 32GB device only has 29.7GB of space).

    Thanks, it's good to know this stuff. Doesn't some of the SD card, flash drive, hard drive, etc. get "eaten up" by formatting, system requirements, and the like?

    Yes, they're all less then the stated amount after formatting. For example a 32GB SD card will have around 29-30GB of usable storage.
