A three-minute song of typical quality will be about 0.003 gigabytes when encoded into MP3 format. The song Tom's Diner by Suzanne Vega was used by AT&T-Bell Labs engineer Karlheinz Brandenburg to test the compression process and is considered the first MP3 song.
It's about 400,000 times as much as a Digital Photo.
In other words, 604 gigabytes is 410,000 times the amount of a Digital Photo, and the amount of a Digital Photo is 0.0000024 times that amount.(5.3 megapixels, JPEG compression, 100% quality, 24 bits/pixel)
A 5.3-megapixel digital camera photo requires about 0.0015 gigabytes of storage space. In 2010, it was expected that 90% of all professionally-taken photographs would be digital instead of film.
It's about 450,000 times as much as a Floppy Disk (3½-in).
In other words, 604 gigabytes is 439,819 times the amount of a Floppy Disk (3½-in), and the amount of a Floppy Disk (3½-in) is 0.00000227366 times that amount.(high density, IBM PC format)
Despite common reference to them as "1.44" megabyte (mB) disks, the actual capacity of the most common model of a 3&-in (8.9 cm) floppy disk is 0.00137329 gigabytes. At the height of their use 1996, there were an estimated five billion disks in use — nearly one for each person on Earth at the time.
It's about 0.00000010 times as much as The Internet.
In other words, 604 gigabytes is 0.0000001 times the amount of The Internet, and the amount of The Internet is 10,000,000 times that amount.(2005 figures) (estimated)
Although the Internet is continuously changing, a 2005 estimate by Google CEO Eric Schmidt was that the total amount of data on the Internet would measure about 5 billion gigabytes (gB). An estimated 1 trillion web pages are published on the Internet, excluding photos, videos, and music content.
It's about 250,000,000 times as much as a Page of Text.
In other words, the amount of a Page of Text is 0.0000000037 times 604 gigabytes.(50 lines, 50 characters per line, ASCII encoding)
A 50-character-per-line, 50-line page of Latin alphabet text requires 0.0000023 gigabytes when digitally represented. The Google Books project, which has produced hundreds of millions of pages of digital text, used a robotic device to digitize over eight million titles at a rate of about 1,000 pages per second.
