: 1 MB = {{gaps|1|024|000}} bytes (= 1000×1024 B) is the definition used to describe the formatted capacity of the 1.44&nbsp;MB {{gaps|3.5-inch}} HD [[floppy disk]], which actually has a capacity of {{gaps|1|474|560|bytes}}.<ref>[http://www.computernostalgia.net/articles/HistoryoftheFloppyDisk.htm Tracing the History of the Computer - History of the Floppy Disk]</ref>

Randomly addressable semiconductor memory doubles in size for each address lane added to an integrated circuit package, which favors counts that are powers of two. The capacity of a disk drive is the product of the sector size, number of sectors per track, number of tracks per side, and the number of disk platters in the drive. Changes in any of these factors would not usually double the size.
