About these units
Storage sizes come in two systems. Decimal (SI) units step by 1,000: 1 KB = 1,000 bytes, 1 MB = 1,000 KB and 1 GB = 1,000 MB. Binary (IEC) units step by 1,024: 1 KiB = 1,024 bytes and 1 MiB = 1,024 KiB. Drive makers and most specifications use decimal units, while Windows and many programs count in binary but label the result KB, MB or GB, which is why a 1 TB drive shows up as about 931 GB. One byte is 8 bits.

› Why does a new drive show less space than advertised?
The box uses decimal gigabytes (10⁹ bytes) while the operating system reports binary gibibytes (2³⁰ bytes) labeled GB. A 500 GB drive is about 465.66 GiB; no space is missing.
