About these units
Block (block)
A block is a unit of data storage used by file systems, typically ranging from 512 bytes to 4096 bytes, though advanced systems may use even larger sizes (8 KB, 16 KB, etc.). Blocks form the fundamental allocation unit for disk storage—files occupy blocks on disk, and file systems track which blocks belong to which files. Block size has significant performance implications. Larger blocks improve read/write throughput but may waste space for small files (internal fragmentation). Smaller blocks offer precision but reduce I/O efficiency. Many classic file systems (FAT, ext2), modern ones (ext4, NTFS), and network storage systems (ZFS, Btrfs, distributed file systems) all rely on block-based allocation. Blocks bridge the gap between raw physical storage and abstract file structures.
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.
