About these units
Zip 250 (Zip 250)
The Zip 250 increased capacity to 250 MB, improving on the Zip 100 line while retaining backward compatibility. It served as a bridge to larger removable storage formats and remained popular until USB flash drives took over the portable storage market. Designers, schools, and offices used Zip 250 disks for medium-sized multimedia projects, backups, and file transfers. Its existence illustrates the rapid pace of storage innovation—and how even seemingly large capacities were quickly eclipsed.
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.
