Under the IEC binary-prefix convention, what unit equals 1,024 gibibytes?

Tebibyte

The IEC introduced binary prefixes like the tebibyte (TiB) to distinguish base-2 measurements from the metric base-10 terabyte (TB). While a terabyte is exactly 1,000 gigabytes, a tebibyte represents 2 to the 40th power bytes, which accounts for the slight discrepancy often seen in computer storage reporting.
