About these units
CD (80 minute) (CD (80 min))
The 80-minute CD expanded storage to 700 MB, offering a modest but meaningful increase over the 74-minute version. This capacity became the industry standard for audio production, software, and media distribution. The slightly denser data-spacing required careful calibration but proved reliable for most computer and consumer hardware. For many users, CD-R and CD-RW discs became a primary means of personal backups, music burning, and long-term storage before USB drives became widespread.
Kilobyte (10^3 bytes) (kB (10^3))
A decimal kilobyte equals 1,000 bytes, reflecting the SI prefix kilo = 10³. Storage device manufacturers standardize on this definition because it scales cleanly and simplifies marketing and specification. This creates a mismatch with binary kilobytes (1,024 bytes) historically used in RAM and file systems. As storage capacities grew, this discrepancy became increasingly noticeable, leading standards bodies to promote explicit binary prefixes (KiB, MiB) for clarity. Despite these efforts, decimal kilobytes remain dominant in contexts such as hard drives, flash memory packaging, and communication standards.
