About these units
Petabyte (PB)
A petabyte is 1 quadrillion bytes in decimal (10¹⁵) or 1,125,899,906,842,624 bytes in binary (2⁵⁰). At this size, storage enters the realm of massive data infrastructures: internet archive collections, large-scale scientific simulations, genomic sequencing databases, machine learning datasets containing billions of records, multinational cloud storage networks. A single PB can store thousands of HD films, millions of e-books, or extensive enterprise backups. Petabytes mark the transition from everyday computing into large-scale data engineering, distributed systems, and global information ecosystems.
Floppy Disk (3.5", DD) (floppy (3.5" DD))
The 3.5-inch Double Density (DD) floppy disk typically held 720 KB of data and represented the evolution from earlier, more fragile 5.25-inch formats. Encased in a rigid plastic shell, 3.5" floppies provided improved durability, portability, and reliability. DD floppies became widely used in the late 1980s, particularly on early Macintosh and IBM-compatible computers. They were ideal for document storage, small software programs, and system utilities. Their limited capacity symbolized the constraints of early personal computing, forcing developers to design highly compact code and carefully manage file size. Despite their modest storage, DD floppies played a crucial role in early software distribution and data portability.
