It's about three-tenths as much as a Page of Text.
In other words, 679 bytes is 0.28 times the amount of a Page of Text, and the amount of a Page of Text is 3.6 times that amount.(50 lines, 50 characters per line, ASCII encoding)
A 50-character-per-line, 50-line page of Latin alphabet text requires 2,500 bytes 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.
It's about six times as much as a Magnetic Stripe Card.
In other words, the amount of a Magnetic Stripe Card is 0.2 times 679 bytes.(maximum capacity; per ISO 7811 specification)
It's about one-two-thousandth as much as a Floppy Disk (3½-in).
In other words, 679 bytes is 0.000460476 times the amount of a Floppy Disk (3½-in), and the amount of a Floppy Disk (3½-in) is 2,171.67 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 1,474,560 bytes. 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 one-two-thousand-five-hundredth as much as a Digital Photo.
In other words, the amount of a Digital Photo is 2,300 times 679 bytes.(5.3 megapixels, JPEG compression, 100% quality, 24 bits/pixel)
It's about one-five-thousandth as much as a MP3 Song.
In other words, the amount of a MP3 Song is 5,000 times 679 bytes.(a.k.a. MPEG-1 Audio Layer 3, a.k.a. MPEG-2 Audio Layer 3) (128 Kbps, "near-CD-quality"; 3 minutes duration; average)
A three-minute song of typical quality will be about 3,000,000 bytes 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 one-eight-thousand-five-hundredth as much as The Complete Works of William Shakespeare.
In other words, the amount of The Complete Works of William Shakespeare is 8,300 times 679 bytes.(ASCII, plain text)
It's about 0.0000009 times as much as a Compact Disc.
In other words, 679 bytes is 0.0000008783 times the amount of a Compact Disc, and the amount of a Compact Disc is 1,139,000 times that amount.(80-minute, 360,000 sector disc; "Red Book" specifications)
