“I’m a whole 607125504 bytes short!”
Same SanDisk Ultra 16 GB stick, same look, new one made in Malaysia, and it holds about 600 MB less. This is not the GB versus GiB excuse. SanDisk’s fine print says part of the capacity goes to “optimizations” and covers itself with “Actual user storage less.” Every other drive he owns shows the full byte count, so only one company found a way to sell you less flash under the same label.
