About these units
Gigabyte (10^9 bytes) (GB (10^9))
A decimal gigabyte is 1,000,000,000 bytes and is the standard unit for hard drive and SSD capacities. As storage technology scaled into the hundreds of gigabytes and then terabytes, the decimal definition became more practical, allowing consistent scaling across consumer and enterprise devices. However, operating systems often report capacities using binary units, causing user confusion (e.g., a "500 GB" drive showing only ~465 "GB"). This mismatch persists despite standardization efforts.
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.
