About these units
Petabyte (10^15 bytes) (PB (10^15))
A decimal petabyte equals 1 quadrillion bytes, a capacity used in cloud data centers, AI training sets, and global archival projects. Organizations like scientific research institutes, major cloud providers, and financial institutions routinely manage petabyte-scale data, requiring specialized infrastructure, redundancy strategies, and data governance. The shift from terabytes to petabytes marks a tipping point where storage strategy must incorporate distributed systems, advanced compression, and scalable metadata management.
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.
