About these units
Terabyte (TB)
A terabyte equals 1,099,511,627,776 bytes (2⁴⁰) in binary or 1 trillion bytes in decimal. Terabytes are associated with large-scale data storage: cloud drives, archival systems, scientific datasets, game installations, and high-definition video libraries. Modern personal computers often include terabyte-level drives, and enterprise systems may contain thousands of terabytes. The TB marks the boundary where storage becomes "big data," enabling machine learning training sets, genomic databases, and detailed satellite imagery archives. At this scale, efficient data management, compression, and redundancy become critical challenges.
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.
