About these units
CD (74 minute) (CD (74 min))
A 74-minute CD typically holds 650 MB of digital data. Originally designed for audio playback, CDs later became a major format for software distribution, backups, and digital media. The 74-minute length was chosen to accommodate Beethoven's Ninth Symphony on a single disc—a blend of engineering, commerce, and cultural symbolism. As CDs pivoted to data storage (CD-ROM), their precise reflectivity patterns and error-correction codes allowed reliable long-term archival. These discs became essential for installing software, distributing games, and storing personal files throughout the 1990s and early 2000s.
Exabyte (10^18 bytes) (EB (10^18))
A decimal exabyte equals exactly 1 quintillion bytes, and it is the standard for expressing large-scale cloud storage and global data production metrics. Industry analysts estimate that total global digital data now exceeds multiple decimal exabytes per year, driven by IoT devices, streaming services, AI workloads, and high-resolution media. The decimal exabyte serves as a measure of humanity's digital footprint, making it one of the most symbolic data units of the information age.
