(BRONTOsaurus BYTE) One quadrillion terabytes. Although the term was coined years ago, and the collective capacity of all the hard drives in the world are nowhere near one brontobyte, we like to think in digital extremes in this industry. After the brontobyte comes "geopbyte" (a thousand brontobytes). Perhaps in the next millennium. See space/time.
