Manufacturers of storage devices usually specify capacity using metric prefixes, so that a terabyte drive would be 1,000 decimal GB = 1,000,000,000,000 bytes rather than the binary 1,024 GB = 1,099,511,627,776 bytes, thus overstating their capacity by nearly 10% compared to the expection of anyone that regards the binary quantities as correct.
