a thousand gigabytes that felt like infinity in 2005 and a Tuesday now
means A unit of digital storage equal to roughly a trillion bytes (1,000 gigabytes, or 1,024 in the binary reckoning), used to measure hard drives, files, and the ever-swelling weight of our data.
from Built from the prefix 'tera-,' adopted into the metric system from the Greek 'teras' meaning 'monster' or 'marvel' — a fitting ancestor for a number so huge — though it was chosen partly because it echoes 'tetra,' the Greek for 'four,' since a terabyte is the fourth power of a thousand. 'Byte' was coined in the 1950s by an IBM engineer, deliberately respelled from 'bite' (a small chunk of data) to avoid confusion with 'bit.' So a terabyte is, etymologically, a monstrous heap of little bites.

google search index — estimated at over 100 terabytes of indexed web data
human brain storage estimate — neuroscientists estimate human memory at approximately 2.5 petabytes, or 2,500 terabytes
large hadron collider — produces about 30 petabytes annually, or 30,000 terabytes of data per year
