It's about one-and-one-tenth times as much as a Blu-ray Disc
In other words, the amount of a Blu-ray Disc is 0.910 times 0.0000000000480 zettabytes.(a.k.a. BD) (dual-layer; Blu-ray disc)
A typical Blu-ray disc will hold 0.0000000000450 zettabytes of data. The increase in capacity versus a standard DVD is possible because of the smaller wavelength of blue light — 405 nanometers instead of 650 nanometers for the red laser light used in a DVD.
It's about one-third as much as an iPod
In other words, the amount of an iPod is 3.03 times 0.0000000000480 zettabytes.(a.k.a. Apple iPod) (2010 figures; for iPod classic, sixth generation)
A sixth-generation, iPod classic MP3 player offers a storage capacity of 0.0000000001460 zettabytes. Data is stored in the unit's hard drive, a 5,400 RPM SATA drive, which measures about 30 sq. cm (5 sq. in)
It's about eleven times as much as a DVD
It's about twelve-and-a-half times as much as an HDTV Television Show (30 Minutes)
In other words, the amount of an HDTV Television Show (30 Minutes) is 0.08 times 0.0000000000480 zettabytes.(a.k.a. High Definition television, a.k.a. HD) (digital signal, QAM-256; 30 minutes)
Broadcast cable HDTV signals contain about 0.000000000000002130 zettabytes of data per second, or 0.000000000003840 zettabytes in a thirty-minute television show. The first High Definition television broadcast was news footage from John Glenn's 1998 mission on the space shuttle Discovery.
It's about 75 times as much as a Compact Disc
In other words, 0.0000000000480 zettabytes is 73.30 times the amount of a Compact Disc, and the amount of a Compact Disc is 0.01364 times that amount.(80-minute, 360,000 sector disc; "Red Book" specifications)
A typical, 80-minute capacity compact disc, commonly known as a 0.00000000000062170 zettabytes disc will actually hold 0.00000000000065490 zettabytes of data. Such disks are 1.2 mm (0.047 in) thick.
It's about one-seventy-fifth as much as Watson
In other words, the amount of Watson is 77 times 0.0000000000480 zettabytes.(data store only)
Watson, the IBM supercomputer famous for competing against humans on the televised trivia game show Jeopardy!, utilizes 0.00000000370 zettabytes of variously-structured data to formulate answers. While "thinking", Watson processes about 0.000000000450 zettabytes of data per second.
