About these units
Floppy Disk (5.25", DD) (floppy (5.25" DD))
The 5.25-inch DD floppy stored roughly 360 KB (IBM PC) or 1.2 MB (Apple II and others) depending on format. These flexible disks dominated early personal computing in the 1980s. They were physically fragile but offered an affordable way to distribute software, operating systems, and games. The vast majority of early PC software—from Lotus 1-2-3 to original DOS versions—shipped on 5.25" disks. Their shape and texture became symbols of the early PC revolution, despite their low reliability, susceptibility to dust, and limited capacity.
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.
