Jaz 1GB (Jaz 1GB)
Iomega's Jaz 1GB drive provided 1 gigabyte of removable storage, making it a high-end solution for professionals in multimedia, CAD, and video editing during the late 1990s. Unlike Zip disks, Jaz cartridges contained hard-disk platters, offering dramatically higher performance and capacity. Jaz drives were essential for users who needed to transport multi-hundred-megabyte project files—something impossible with floppies or Zip 100 disks. However, Jaz drives were expensive and prone to hardware failures, limiting their adoption. They represent early attempts to scale removable storage before the solid-state era.
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.
